Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Apnea events occur in most neonates, for whom monitoring is usually performed using a monitor. The present monitor can monitor the breathing condition of a newborn, and specifically, a heart rate real-time waveform and a heart rate real-time value, a blood oxygen related parameter real-time waveform and a blood oxygen related parameter real-time value, a breathing real-time waveform and a breathing frequency real-time value, and the like are displayed on a breathing oxygenation monitoring interface. If the monitor finds the apnea condition of the infant to be detected, alarm prompt information pops up above the respiratory oxygenation monitoring interface and gives an alarm along with sound.
However, many alarm events in the monitor use the same prompting method, and it is not easy to distinguish apnea events and other alarm events.
It should be noted that the medical device referred to in the present application may be not only a monitor, but also a device that can be used for monitoring vital signs, such as an invasive/noninvasive ventilator. The following embodiments are mainly described by taking a monitor as an example.
Referring to fig. 1, a flow chart of an apnea event monitoring method provided herein is shown. The method can be applied to various medical devices, such as monitors, ventilators, and the like. The monitored objects may be various types of objects such as newborns.
As shown in fig. 1, the process specifically includes steps 1.1-1.5.
Step 1.1: real-time data of at least one physiological sign parameter of the target subject is obtained by at least one physiological parameter sensor. It should be noted that the real-time data mentioned in the application may be data measured continuously by the physiological parameter sensor or data measured at certain time intervals.
The target object is not limited to a newborn, and may be other types of monitored objects. Besides the parameters such as blood pressure, electrocardiogram and body temperature, the physiological parameters at least include parameters related to apnea, such as heart rate, pulse rate, blood oxygen related parameters, respiratory rate, etc., in order to monitor the state related to apnea of the target subject. Wherein the duration of the apnea can be determined from the breathing rate. It should be noted that the acquired physiological parameters are basic data for determining whether an apnea event can be triggered. Of course, in other embodiments, it is not excluded that other physiological parameters are taken into consideration when determining an apneic event.
The physiological parameters collected by the sensor can be sent to a storage module of the monitor for storage, and the basic data can be used as analysis data for analyzing various respiratory events such as apnea events and respiratory oxygenation events in apnea related states. That is to say, the physiological sign parameter can be obtained from the storage module by the sensor storing the physiological sign parameter into the storage module of the monitor. Of course, the physiological parameters can also be obtained directly from the sensors.
Therefore, the apnea event monitoring method provided by the application can be applied to not only bedside equipment but also a central station. When the device is applied to bedside equipment, the physiological sign parameters are obtained through accessory equipment of various physiological parameters; when the system is applied to the central station, the central station acquires real-time data of the physiological sign parameters from the bedside equipment through the network.
Step 1.2: a monitoring interface is provided that includes a dedicated display area for apneic events and a display area for displaying real-time data of at least one physiological sign parameter.
The monitoring interface can be a main monitoring interface on a display of the medical equipment, and the real-time data of the physiological sign parameters at least comprises real-time waveforms and/or numerical values of various physiological sign parameters after being displayed on the main monitoring interface. The dedicated display area for an apneic event may be a block area embedded in the monitoring interface or a window area hovering over the monitoring interface. The location attribute, shape attribute, display attribute, status attribute, etc. of the dedicated display area may be adjustable. For example, the position attribute of the dedicated display area refers to the display position of the dedicated display area on the main monitoring interface; the shape attribute of the dedicated display area includes the style, size, etc. of the shape, for example, the shape may be various, such as rectangular, circular, heart, etc.; the display attribute of the dedicated display area refers to attribute information such as color, brightness, contrast and the like of all or part of the display area; status attributes of the dedicated display area include visible or invisible attributes, embedded or hovering over a monitoring interface, and the like. According to the identification result of the apnea event, for example, the identification result may include an event type, an event priority, an event risk degree, attention content corresponding to the apnea event, and the like of the apnea event, the monitoring importance degree, the event priority, the event risk degree, the event type, and the like of the apnea event are displayed by adjusting one or more of shape attributes, display attributes, state attributes, and the like of the dedicated display area.
In some embodiments, the dedicated display area belongs to a sub-area in the monitoring interface, that is, the dedicated display area is embedded in the monitoring interface, displayed following the display of the monitoring interface, and disappears following the disappearance of the monitoring interface. Alternatively, in some embodiments, the dedicated display area further has a separate control button for turning on and off, and when the on button is triggered, the state attribute of the dedicated display area is switched so that the dedicated display area is displayed at a certain position of the monitoring interface, and when the off button is triggered, the state attribute of the dedicated display area is switched so that the dedicated display area disappears from the monitoring interface. Of course, as further described below, when the dedicated display area is turned off, if an apnea event is detected as being triggered, the state attribute of the dedicated display area may be switched so that the dedicated display area is automatically displayed as a prompt. It should be noted that the dedicated display area does not limit the position of the area in the monitoring interface to be fixed, and may be movable, for example, the position attribute of the dedicated display area may be adjusted according to the sliding track of the touch operation, so that the display of the dedicated display area may move along with the touch operation.
The dedicated display area may be used to reflect the respiratory event context associated with the apneic event, and for ease of understanding, the knowledge of the apneic event will be described first.
Step 1.3: obtaining a target physiological sign parameter of the target subject related to the apnea event from the at least one physiological sign parameter. The target physiological sign parameter belongs to parameters related to an apneic event, such as apneic duration, blood oxygen saturation, heart rate, pulse rate, and the like.
Step 1.4: an apnea event is identified from real-time data of a target physiological sign parameter.
The standard of identification of the apnea event can be various, and the alarm conditions of different monitors of the standard of identification are different. If the standard of the apnea event is low, for example, mild respiratory events such as periodic breathing are also considered as the apnea event, the alarm is frequently given, so that medical staff frequently start an emergency treatment program, and medical resources are wasted.
However, the apnea event, physiological parameters and parameter thresholds in this application are determined after intensive studies on the apnea problem of the neonate.
In particular, when studying neonatal apnea, it was found that severe respiratory events are mostly related to the duration of apnea, and longer duration of apnea indicates more severe condition, and thus the duration of apnea is determined as a main parameter of concern for the apnea event. Studies have also found that during the onset of apnea, symptoms of hypoxemia or bradycardia are often accompanied. Therefore, the blood oxygen saturation value and the heart rate (of course, the pulse rate) are used as two other important parameters for the apnea event.
From clinical observations, severe apneic events, apneic duration typically longer than 20 seconds, or apneic duration longer than 10 seconds with blood oxygen saturation values less than 80%, or apneic duration longer than 10 seconds with heart rates below 100bpm (Beat Per Minute). The threshold value of the physiological sign parameter of the apnea event is set according to a judgment condition. Of course, the above numerical values may be other values set according to actual monitoring requirements, and the present application is not limited specifically.
In summary, the target physiological parameters related to the apneic event may include three parameters, namely, the duration of the apnea, the blood oxygen saturation value, and the heart rate (or pulse rate, which may be described as the heart rate since the pulse rate and the heart rate generally represent the same physiological state), which have respective corresponding thresholds indicating the occurrence of the apneic event when one or more of the parameters reach the above-mentioned decision condition.
In some embodiments, a new method of monitoring for apnea events is also employed, as described below.
Firstly, obtaining real-time data of target physiological sign parameters of a target object, wherein the real-time data of the target physiological sign parameters are obtained through at least one physiological parameter sensor;
secondly, identifying continuous apnea from real-time data of the target physiological sign parameters;
the occurrence of an apnea event is then identified from the real-time data of the target physiological sign parameter based on the identification of apnea duration. In the present embodiment, the target physiological parameters may include at least one or more of respiration rate, pulse rate, blood oxygen related parameters.
In some of these embodiments, identifying the occurrence of an apnea event from the real-time data of the target physiological sign parameter based on the identification of apnea duration comprises: and determining that one of the following judgment conditions occurs in the time period of the duration of the apnea based on the identification result of the duration of the apnea, and then determining that the apnea event occurs: the duration of the apnea reaches a first duration threshold; the duration of the apnea reaches a second duration threshold, and a condition that the blood oxygen related parameter is lower than the blood oxygen related parameter threshold exists in the apnea duration; the duration of the apnea reaches a second duration threshold, and a condition that the heart rate is lower than the heart rate threshold occurs within the duration of the apnea; the apnea duration reaches a second duration threshold and a condition occurs where the pulse rate is below the pulse rate threshold for the apnea duration.
Of course, it should be understood that in these embodiments, the determination condition already includes that the apnea duration reaches the second duration threshold, and that both the blood oxygen related parameter being below the blood oxygen related parameter threshold and the heart rate being below the heart rate threshold (or the pulse rate being below the pulse rate threshold) occur within the apnea duration.
As described above, typically, the first duration threshold may be set to 20 seconds, the second duration threshold may be set to 10 seconds, the blood oxygen related parameter threshold may be set to 80%, and the heart rate threshold and pulse rate threshold may be set to 100 bpm. Of course, in other embodiments, the first duration threshold, the second duration threshold, the blood oxygen related parameter threshold, the heart rate threshold, and the pulse rate threshold may be set to other values by the user according to the actual situation.
Additionally, in some further embodiments, identifying the occurrence of an apnea event from the real-time data of the target physiological sign parameter based on the identification of apnea duration comprises:
first, based on the identification of the apnea duration, an event segment containing at least one apnea duration is obtained from the real-time data of the target physiological sign parameter. An event segment includes real-time data of physiological parameters within a preset statistical duration, where the statistical duration can be 3 minutes, 4 minutes, and so on. An event segment comprising a first time period before the apnea trigger time point and a second time period after the apnea trigger time point (typically, the second time period is greater than the apnea duration; in some cases, it may be that the apnea has not actually ended and the event segment has ended, i.e., the second time period is less than the apnea duration); alternatively, an event segment comprises a time period from the apnea trigger time point comprising the duration of the apnea. The definition of the first time period and the second time period is referred to herein in relation to the position. Apnea trigger time points were: detecting a starting time point of apnea from real-time data of a target physiological sign parameter; or detecting a time point when the apnea continuously passes a second duration threshold from the real-time data of the target physiological sign parameters; or detecting a time point when any one of the heart rate, the pulse rate and the blood oxygen related parameter value is lower than the corresponding preset threshold value from the real-time data of the target physiological sign parameter.
Secondly, determining the maximum value, such as the minimum value or the maximum value, of the target physiological sign parameter based on the real-time data of the target physiological sign parameter corresponding to the event segment.
Then, within a dedicated display area on the monitoring interface, the most value of the target physiological sign parameter is output and displayed, for example, one or more of the following parameters are output and displayed within the dedicated display area: a maximum value for the duration of an apnea, a minimum value for a blood oxygen related parameter value for the duration of an apnea, and a minimum value for the heart rate or pulse rate for the duration of an apnea.
The blood oxygen related parameters mentioned herein may be: blood oxygen saturation, oximetry wave, rSO2 tissue oxygen saturation, SaO2 arterial oxygen saturation, transcutaneous blood oxygen parameter. Of course, it is not excluded that in some cases the following blood oxygen related parameters may be used to achieve the object of the present invention: pO2 partial pressure of oxygen, Pulse Variability Index (PVi), total hemoglobin (SpHb), methemoglobin (SpMet), carboxyhemoglobin (SpCO), total oxygen content (SpOC), Oxygen Reserve Index (ORi), oximetroplethysmography (RRp). The following embodiments are specifically described using blood oxygen saturation as a preferred embodiment.
Step 1.5: and outputting and displaying in the special display area according to the recognition result of the apnea event.
As shown in fig. 2, in one embodiment, steps 1.4-1.5 may include: determining an apnea event segment meeting the determination condition of the apnea event from the real-time data of the target physiological sign parameters; and determining the attention content based on the data corresponding to the apnea event segment, and outputting and displaying the attention content in the special display area.
Fig. 2 shows an example of a monitoring interface generated by applying the monitoring method provided by the present embodiment. As shown in fig. 2, the monitoring interface includes a dedicated display area, and the other portions of the monitoring interface except the dedicated display area are represented by oblique lines to display the real-time data of the physiological parameters. The special display area is used for reflecting the related situation of the apnea event, the attention content is displayed in the special display area, and the medical staff can determine whether the target object has the apnea event or not and what the severity of the apnea event is by observing the attention content in the special display area.
And analyzing the target physiological sign parameters according to the data content to be displayed in the special display area, so as to obtain the attention content corresponding to the data content. The information displayed in the dedicated display area is information related to an apnea event that is relatively focused by the medical staff, and therefore, in the embodiment of the present application, the information is referred to as a focused content.
The presentation form (style, content, etc.) of the content of interest is different in different cases, and whether an apnea event has occurred and related information of the apnea event can be determined according to the presentation style of the content of interest.
When an apnea event occurs, the medical staff can reflect the severity of the apnea event to a certain extent by comparing the data content of interest, and therefore, the content of interest in this case can be considered to represent the severity of the apnea event. It should be noted that the content of interest reflects the severity of the apnea event objectively and meets the objective cognitive criteria of people. For example, in an apneic event, objective cognition considers an apneic event to be more severe if the heart rate or pulse rate of the target subject is lower, and thus the content of interest may include the lowest value of heart rate in the event segment. As another example, in an apnea event, if the target subject's blood oxygen saturation value is lower, the apnea event is considered to be more serious in objective cognition, and thus the attention content may include the lowest value of the blood oxygen saturation value in the event segment. As another example, in an apneic event, if the target subject's apneic duration is longer, the apneic event is also considered objectively more severe, and thus the content of interest may include the maximum value of the apneic duration in the event segment.
Under different monitoring requirements, the concerned physiological sign parameters are different, so that the concerned contents are also different. How to determine and display the attention content is described below by specific examples, which are not described herein in detail.
If the physiological sign parameters cannot trigger an apnea event, that is, the target subject does not have apnea, a preset content may be used as the content of interest, where the preset content is a content capable of indicating that the apnea event does not occur. For example, the preset content may be null or may be in the form of "normal".
The attention content has two states, the special display area is a display area which can be switched between the two states, if an apnea event does not occur, the attention content in the area is displayed in one form, and if the apnea event occurs, the attention content in the area is displayed in another form. In order to prompt more obviously, a background color can be set for the special display area, and the background color is displayed in a flashing mode in a reversed color mode to play a role in warning in the case of an apnea event.
According to the technical scheme, the method for monitoring the apnea event, provided by the embodiment of the application, can provide a special display area in a monitoring interface, determine the attention content based on the data corresponding to the apnea event segment, enable the attention content to reflect the severity of the apnea event, and display the attention content in the special display area. Therefore, medical staff can determine whether an apnea event occurs by directly observing the attention content in a special display area in the interface, and know the severe condition of the apnea event of the monitored object.
At present, after an apnea event occurs, an alarm bar is displayed above a respiration oxygenation interface, the alarm bar only needs to prompt medical staff of an emergency event, based on the thought, the alarm bar is a rectangular prompt area, and characters such as an alarm and an apnea event can be written in the prompt area. The alarm bar is placed on top of the monitor in order not to affect the display of the respiration waveform and respiration rate in the main interface.
This type of prompting is not obvious enough to provide more apneic event information to the caregiver that the caregiver needs to obtain by other means. For example, it is desirable to calculate the duration of an apnea by observing the time of a flare in the respiratory waveform at bedside, or to look through the respiratory trend table data to find the lowest value of the blood oxygen saturation value and the lowest value of the heart rate. It can be seen that the current respiration and oxygenation interface cannot display various attention values capable of reflecting the severity of the apnea event, and medical staff cannot directly judge the severity of the apnea event from the current respiration and oxygenation interface.
Compared with the existing mode of prompting the alarm strip above the respiration oxygenation interface, the monitoring method provided by the application is a special display area of the apnea event in the monitoring interface so as to be different from other alarm events, and the information displayed in the special display area can provide direct rescue reference information for medical staff, so that the apnea event can be processed more quickly and efficiently.
Of course, in one embodiment, the apnea event monitoring method further comprises: identifying an alarm event from real-time data of at least one physiological sign parameter, the alarm event comprising an alarm event based on a single physiological sign parameter, and/or a combined alarm event based on more than two physiological sign parameters; displaying the alarm event in a display area on the monitoring interface except the dedicated display area. In particular, the display area for alarm events may be the alarm bar area described above.
As shown in fig. 3A, in one embodiment, the apnea event determination conditions are: the duration of the apnea reaches a first time threshold; or the duration of the apnea reaches a second duration threshold, and a condition that the blood oxygen related parameter is lower than the blood oxygen related parameter threshold exists in the duration of the apnea; or the duration of the apnea reaches a second duration threshold, and a condition that the heart rate is lower than the heart rate threshold occurs within the duration of the apnea; alternatively, the apnea duration reaches a second duration threshold and there is an occurrence of a pulse rate below the pulse rate threshold for the apnea duration. Wherein the first duration threshold is greater than the second duration threshold. As described above, generally, the first duration threshold may be set to 20 seconds, the second duration threshold may be set to 10 seconds, the blood oxygen saturation threshold may be set to 80%, and the heart rate threshold and the pulse rate threshold may be set to 100 bpm. Of course, in other embodiments, the first duration threshold, the second duration threshold, the blood oxygen saturation threshold, the heart rate threshold, and the pulse rate threshold may be set to other values by the user according to the actual situation.
Specifically, in order to monitor the apnea event and meet various monitoring requirements in practical application, a pair of parameter setting interfaces for the apnea event may be provided, and the setting interfaces include a physiological sign parameter setting control and a parameter threshold setting control, so as to flexibly set physiological sign parameters and parameter thresholds related to the apnea event.
One parameter setting interface for an apnea event is shown in fig. 3A, and includes a physiological sign parameter setting area 301 and a statistical duration setting area 302.
The physiological sign parameter setting area 301 includes: heart Rate (HR) setting, blood oxygen saturation (SpO2) setting, and Apnea (Apnea) setting. The heart rate setting mainly relates to a heart rate threshold setting control and a heart rate threshold duration setting control; the oxyhemoglobin saturation setting mainly relates to an oxyhemoglobin saturation threshold setting control and an oxyhemoglobin saturation threshold duration setting control; the apnea setting is primarily related to an apnea duration threshold setting control.
In practical applications, the heart rate threshold may be input into the heart rate threshold setting control, and set to 100bpm (Beat Per Minute) as shown in fig. 3A, and the duration corresponding to the heart rate threshold may be input into the heart rate threshold duration setting control, and set to 10s (seconds) as shown in fig. 3A. Similarly, the blood oxygen saturation level threshold may be input in the blood oxygen saturation level threshold setting control, set to 80% as shown in fig. 3A, and the duration of the blood oxygen saturation level threshold may be input in the blood oxygen saturation level threshold duration setting control, set to 0s (seconds) as shown in fig. 3A. The apnea duration threshold may be entered in the apnea duration threshold setting control and set to 10s (seconds) as shown in fig. 3A.
The significance of setting the duration of the heart rate threshold and the duration of the blood oxygen saturation threshold is that, clinically, the situations that the monitored value of a patient such as a newborn becomes low instantly and returns to normal are more, and in order to avoid unnecessary alarm, the duration is used as a trigger sub-condition, that is, the target physiological sign parameter is required to reach the threshold, and the apnea event is likely to be triggered only by further requiring the duration to be a certain duration.
The controls can set parameter thresholds of the physiological sign parameters, and the determination conditions formed by the physiological sign parameters can be set in other ways. The decision condition may comprise one or a combination of the above physiological sign parameters. For example, a heart rate threshold of 100bpm and a heart rate threshold duration of 10 seconds may be reached and an apneic event may be triggered; as another example, the apnea duration reaches 10 seconds, the heart rate threshold reaches 100 and the heart rate threshold duration reaches 10 seconds; for another example, the duration of apnea reaches 10 seconds, and the blood oxygen saturation value is less than 80%; and so on.
Therefore, in an embodiment, on the basis that the blood oxygen saturation value is lower than the blood oxygen saturation threshold, the determination condition further includes that the duration of the blood oxygen saturation value lower than the blood oxygen saturation threshold exceeds a preset duration; on the basis that the heart rate is lower than the heart rate threshold value, the judgment condition further comprises that the duration time of the heart rate lower than the heart rate threshold value exceeds a preset time; on the basis that the pulse rate is lower than the pulse rate threshold, the judgment condition further comprises that the duration of the pulse rate lower than the pulse rate threshold exceeds a preset duration.
In one embodiment, the apnea event segment includes a first time period before an apnea trigger time point and a second time period after the apnea trigger time point. As shown in fig. 3A, the value of the statistical time duration may be set in the statistical time duration setting region 302, and may be set to 2min (minutes) plus 2 min. In the form of a two-part addition, the first part of the duration represents a first time period before the apnea trigger and the second part represents a second time period after the apnea trigger. From clinical experience, it is known that a statistical duration of 4 minutes for an apnea event segment is a reasonable duration, although other values are possible and are not limited to 2+2, and may be 1+3 or 3+1, and so on. In summary, the statistical time of an apnea event segment comprises or partially comprises a time period of the duration of an apnea.
The significance of setting the statistical duration is that the threshold of the physiological parameter triggering apnea, such as the heart rate threshold and/or the blood oxygen saturation threshold, is continuous, and the most value can be determined only in a limited number of values, so that a statistical duration setting area is arranged in the interface to set the duration needing to be counted, the counted value in the duration is limited, and the most value of the physiological parameter can be determined in the limited data.
It should be noted that the physiological sign parameter may be associated with an apnea related state, and is used to trigger the apnea related state corresponding to the physiological sign parameter. For example, the heart rate threshold may be associated with bradycardia, extreme bradycardia, or hypocardia; the blood oxygen saturation threshold may be associated with a low blood oxygen saturation limit; the apnea duration may be associated with an apnea delay, an apnea delay.
For example, if the heart rate threshold is set to 100bpm and the heart rate value reaches (means is lower than) 100bpm, it can be considered that bradycardia occurs; if the heart rate threshold is set at 80bpm and the heart rate value reaches (meaning below) 80bpm, it is assumed that extreme bradycardia has occurred.
Based on this, in the apnea event method provided in this embodiment, the determination condition of the apnea event includes detecting an alarm event that the duration of the apnea event reaches a first time threshold; or detecting that the duration of the apnea reaches a second duration threshold, and an alarm event that the blood oxygen related parameter is lower than the blood oxygen related parameter threshold exists in the duration of the apnea; or detecting that the duration of the apnea reaches a second duration threshold, and storing an alarm event that the heart rate is lower than the heart rate threshold in the duration of the apnea; or detecting that the duration of the apnea reaches a second duration threshold, and an alarm event with a pulse rate lower than the pulse rate threshold exists in the duration of the apnea.
In this embodiment, the apnea triggering time points are: detecting a starting time point of an apnea event from real-time data of a target physiological sign parameter; alternatively, a point in time at which the apneic event persists past the second duration threshold is detected from the real-time data of the target physiological sign parameter.
Also, another parameter setting interface for apnea events is provided in this embodiment. Respiratory alarm events may include bradycardia alarms, low blood oxygen saturation limit alarms, apnea delay alarms, and the like.
As shown in fig. 3B, the physiological sign parameter setting area 311 and the statistical duration setting area 312 are included. This interface is different from the interface of fig. 3A in that the physiological sign parameter setting control is replaced with an apnea-related state setting control. For example, the setting control of the heart rate threshold is replaced by a cardiac state setting control, and the cardiac state can be set to bradycardia, extreme bradycardia or too low heart rate, and the like, as shown in fig. 3B, the setting control is set to bradycardia; as another example, the setting control of the blood oxygen saturation threshold is replaced by a blood oxygen saturation state setting control, as shown in fig. 3B, the blood oxygen saturation state may be set as a low blood oxygen saturation limit; for another example, the apnea duration setting control may be replaced with an apnea state setting control, as shown in FIG. 3B, and the apnea state may be set to apnea. The determination conditions for various apnea-related conditions can be found in the above description, and are not described herein.
It should be noted that, for the description of the other controls in the interface, reference may be made to the description in the above illustration, and details are not described here.
The following is a detailed description of how to determine the attention content based on the physiological sign parameters and how to display the attention content in the case that the physiological sign parameters can trigger an apnea event.
Assuming that the physiological parameters of the apnea event include any one or more of the combination of the duration of the apnea, the blood oxygen saturation and the heart rate, the specific way of determining the content of interest according to the physiological parameters includes:
if the physiological sign parameters comprise the duration of apnea, determining the maximum value of the duration of apnea in the event segment;
if the physiological sign parameters comprise the blood oxygen saturation value, determining the lowest value of the blood oxygen saturation value in the event segment;
if the physiological parameters comprise heart rate, determining the lowest value of the heart rate in the event section.
In order to obtain the maximum value of each physiological parameter, a statistical time duration, i.e., the above-mentioned event segment, needs to be set, and the value obtained in this limited time duration is limited, so that the maximum value of the physiological parameter can be determined in the limited data. The length of the statistical time period may be preset, such as 4 minutes.
When the maximum value of the duration of the apnea is determined, comparing the duration of each apnea in the event segment, and determining the maximum value; of course, typically, there is only one apnea duration interval within an event segment. Similarly, the blood oxygen saturation value and the most significant value of the heart rate in an event segment can be determined. Therefore, in the identification of an apneic event, it is necessary to identify an event segment containing at least one apneic duration.
The attention content is displayed in the dedicated display area, and in the case where the attention content includes the above-described three types of the most value, one display manner of the dedicated display area is shown in fig. 4A, and the three attention contents are displayed in the same area.
As shown in fig. 4A, the patent display area 401 includes: apnea 23 seconds, heart rate minimum 60bpm, blood oxygen minimum 78%. The apnea is short for the maximum value of the duration of the apnea, and the blood oxygen is the lowest value of the blood oxygen saturation value, so that the area space can be saved in a short way, and the medical staff can conveniently check the apnea and the blood oxygen. In practical applications, other shorthand methods may be used, such as Apnea (Apnea) for maximum duration of Apnea, Desaturation for minimum blood oxygen saturation, and Bradycardia for minimum heart rate.
According to clinical experience, the three physiological parameters of apnea events are the most interesting parameters for medical staff, and therefore, the maximum value of the duration of apnea is displayed in a more prominent manner in the dedicated display area than the lowest value of the blood oxygen saturation value and the lowest value of the heart rate. As shown in fig. 4A, the highlighted style may be display position first, font bolded, and font larger. Of course, the highlighting pattern is not limited to the manner shown in fig. 4A, and other manners such as adding a background color, different font colors, highlighting, flashing, and the like may be used.
One display mode of the dedicated display area is to display three pieces of attention content in three different sub-areas, respectively. Namely: in the special display area, determining sub-areas corresponding to the duration of apnea, the blood oxygen saturation value and the heart rate respectively; and respectively displaying the maximum value of the duration of the apnea, the minimum value of the blood oxygen saturation value and the minimum value of the heart rate in each sub-area.
As shown in fig. 4B, the dedicated display area 411 includes three sub-areas, which respectively display: apnea 23 seconds, heart rate minimum 60bpm, blood oxygen minimum 78%. In order to highlight the numerical value, the numerical value may be displayed in a large font, and a highlight pattern such as a shading may be provided.
Further, after obtaining the heart rate minimum, the duration of the heart rate minimum may also be obtained and included in the content of interest for display in the display area. As shown in fig. 4B, 14 seconds may be included after the lowest heart rate value of 60bpm to indicate that the lowest heart rate value of 60bpm lasts for 14 seconds.
In another embodiment, the apnea event segment includes a time period from an apnea trigger time point including an apnea duration.
In practical applications, statistics of apnea events occurring over a historical period of time may also be included in the monitoring interface. Specifically, the method comprises the following steps: obtaining respiratory oxygenation events from real-time data of the target physiological sign parameters, the respiratory oxygenation events not including apneic events; determining a type of respiratory event from the apnea event and the respiratory oxygenation event; the type of respiratory event is recorded. Wherein the respiratory events include apnea events and respiratory oxygenation events.
In particular, respiratory events may include respiratory oxygenation events in addition to apnea events. These are two different types of respiratory events, with apnea events being more severe and respiratory oxygenation events being less severe than apnea events, but still requiring warning to the healthcare staff to be concerned. Thus, in one of the embodiments, the type of respiratory event referred to herein may be for distinguishing whether an occurring respiratory event is an apneic event or a respiratory oxygenation event.
Apnea events are relatively more critical to the determination of respiratory oxygenation events, and may be characterized by more physiological parameters or more critical parameter thresholds for triggering events.
For example, respiratory events involve three physiological parameters, namely Apnea duration, blood oxygen saturation, and heart rate, and Apnea (or simply a) may be used to represent Apnea duration, Desaturation (or simply D) may be used to represent blood oxygen saturation, and Bradycardia (or simply B) may be used to represent heart rate. The decision condition for an apneic event may be: the determination condition of the respiratory oxygenation event may be any one of BD, B, and D, among ABD, AB, AD, and a. In one embodiment, the type of respiratory event is differentiated based on different alarm event types corresponding to different target physiological sign parameters. For example, a type a event represents an alarm event regarding the duration of an apnea, e.g., the duration of an apnea exceeds a corresponding threshold; type B events represent alarm events regarding heart rate and/or pulse rate, e.g., heart rate and/or pulse rate is below a respective threshold; type D events represent alarm events regarding blood oxygen saturation, e.g., blood oxygen saturation is below a respective threshold; the AB type event represents that the A type event and the B type event occur simultaneously; the ABD event represents that an A type event, a B type event and a D type event occur simultaneously; the AB event represents that the type A event and the type B event occur simultaneously; the AD event represents that the type A event and the type D event occur at the same time, and the BD event represents that the type D event and the type B event occur at the same time; and so on.
It should be noted that, what kind of physiological parameters are included in the determination condition indicates which kind of physiological parameters have values reaching the corresponding parameter threshold; if the judgment condition comprises a plurality of physiological sign parameters, the judgment condition indicates that the plurality of physiological sign parameters are required to simultaneously reach corresponding parameter thresholds when the respiratory event is triggered.
If the physiological sign parameter of the target object meets one of the determination conditions, a respiratory event corresponding to the condition is triggered, and the respiratory event is an apnea event or a respiratory oxygenation event.
For example, if the duration a of apnea and the heart rate B of the physiological parameters of the target subject satisfy the determination condition, the type of respiratory event is determined as AB. For another example, if the duration a of apnea and the blood oxygen saturation D in the physiological parameters of the target object simultaneously satisfy the determination condition, the type of respiratory event is determined as AD. For another example, if the blood oxygen saturation level D satisfies the determination condition among the physiological sign parameters of the target subject, the type of the respiratory event is determined as D.
After the type of respiratory event is determined, a record may be saved. The type of respiratory event recorded may be used for subsequent statistical display.
In one embodiment, the method of monitoring for apnea events further comprises: acquiring an apnea event occurring within a historical time period of a preset duration; an event list area is provided within the monitoring interface in which a list of the apneic events is displayed.
Further, the apnea event monitoring method further comprises: obtaining respiratory oxygenation events occurring within a historical time period of a preset duration; a list of respiratory oxygenation events is also displayed within the event list region.
Specifically, the respiratory event occurred in the target object is recorded, and the time point of the respiratory event is recorded as an attribute of the respiratory event. In order to facilitate the medical staff to know the frequency of the respiratory events of the target object, an area can be added in the monitoring interface, and the area contains the respiratory events of the target object within a preset period of time.
The respiratory events within the region may be ordered, sequenced or reversed in order of the time points of occurrence. For convenience of description, the area may be referred to as an event list area. One form of the preset time period is a historical time period of a preset duration before the current time point, for example, within the past 24 hours.
The method comprises the steps of obtaining respiratory events occurring within a preset time period, wherein the respiratory events may include apnea events and respiratory oxygenation events, and different display styles can be used for displaying the apnea events and the respiratory oxygenation events respectively for medical staff to distinguish conveniently because respiratory problems represented by different types of respiratory events are different in severity. The different display styles may include, but are not limited to, color, font weight, italic whether to underline, whether to add an identifier, and the like.
The respiratory events displayed in the event list area may include the type of respiratory event, the time point of occurrence, the most significant value of the included physiological sign parameter, and the like.
See fig. 5A, which shows an example of a respiratory event. As shown in fig. 5A, the monitoring interface may further include an event list area 502 on the basis of the display area 501. The event list area 502 contains respiratory events that occurred within the past 24 hours, which are:
09:30, wherein the apnea duration a has a maximum value of 12 seconds, the heart rate B has a minimum value of 91bpm, and the blood oxygen saturation D has a minimum value of 79%;
a respiratory event a occurs at 08:43, wherein the apnea duration a has a maximum value of 21 seconds;
03, with an apnea duration a of 17 seconds at the maximum and a heart rate B of 82bpm at the minimum;
02:25 occurrence of an AD respiratory event in which the apnea duration a has a maximum value of 19 seconds and the blood oxygen saturation D has a minimum value of 72%;
01:40, with a minimum of 91bpm for heart rate B and 85% for blood oxygen saturation D.
It should be noted that the most value of the physiological parameter is calculated within a preset statistical time period, and if the physiological parameter includes an apnea duration and the statistical time period is over, the state of apnea still occurs in the respiration, a mark such as a plus sign "+" may be added after the value of the apnea duration to indicate that the apnea state is persistent. For example, a respiratory event of 08:43, including "+" after 21 seconds of apnea duration a. Additionally, the statistical duration of 24 hours for a respiratory event in FIG. 5A may be set to other values, such as 12 hours, by the setting interface. In some embodiments, a touch button may be provided in the event list area 502, a duration selection interface may be popped up in response to an instruction input by the user, and an event list corresponding to the duration selected by the user in the event list area 502 may be updated in response to the duration selected by the user.
In one embodiment, the apnea event and the respiration oxygenation event are displayed separately in different display patterns within the event list region
In one implementation, the apnea event monitoring method further comprises: obtaining a oscillogram of the target physiological sign parameters; and setting a graphic area in the monitoring interface, and displaying a target physiological sign parameter oscillogram in the graphic area.
Specifically, the waveform diagram of the heart rate is a heart rate trend diagram, the waveform diagram of the blood oxygen saturation is a blood oxygen saturation trend diagram, and the waveform diagram related to apnea is a compressed respiration waveform diagram. The target physiological parameter oscillogram can be refreshed in real time according to the real-time data of the monitored target physiological sign parameters.
The heart rate trend graph can be obtained based on the electrocardio monitoring result and the pulse rate monitoring result; the compressed respiration waveform map may be based on impedance respiration monitoring results, or may be based on exhaled gas monitoring results, such as those of exhaled carbon dioxide monitoring.
See fig. 5B, which shows yet another example of a monitoring interface. As shown in fig. 5B, the monitoring interface further includes a graphic area 512 on the basis of the dedicated display area 511. The graph area 512 contains three waveforms, which are a heart rate trend graph, a blood oxygen saturation trend graph, and a compressed respiration waveform graph. The waveform corresponds to a time period of 6 minutes.
Further, the waveform of the target physiological sign parameter may further include a parameter threshold for triggering an apnea event, such as a parameter threshold of 100bpm for heart rate indicated by a dashed line in a heart rate trend graph, and a parameter threshold of 80% for blood oxygen saturation indicated by a dashed line in a blood oxygen saturation trend graph.
Further, if the parameter value of the target physiological parameter reaches the parameter threshold and triggers an apnea event, the area corresponding to the apnea event may be marked in the target physiological parameter waveform.
To facilitate the healthcare worker's review of the apnea event in the schematic, the apnea trigger time point may be marked on the target physiologic parameter waveform, and/or the apnea event segment may be marked on the target physiologic parameter waveform.
As shown in fig. 5B, in the graphical region 512, an apnea event is marked, which occurs at 9 o' clock 30, and the monitoring time interval is 1 minute before the time and 3 minutes after the time. The manner of marking the occurrence time point includes a marking line perpendicular to the time axis and a text prompting the time point. The way of marking the monitoring time interval includes adding a background shading within the time region in the waveform map.
See fig. 5C and 5D, which illustrate yet another example of a monitoring interface. As shown in fig. 5C, the monitoring interface may further include an event list area 522 and a graphic area 523 based on the dedicated display area 521. For the description of the event list area and the graphic area, reference is made to the description of fig. 5A and 5B. It should be noted that the english concept in fig. 5D has the same meaning as the chinese concept at the position corresponding to fig. 5C.
See fig. 5E and 5F, which illustrate yet another example of a monitoring interface. As shown in fig. 5E, the monitoring interface may further include a graphic area 532 based on the dedicated display area 531.
The special display area is divided into a plurality of sub-areas, and different sub-areas correspond to different types of physiological sign parameters. In this case, the physiological sign parameter oscillogram included in the monitoring interface can be displayed corresponding to the sub-region of the physiological sign parameter. As shown in fig. 5E, the dedicated display area 531 and the graphic area 532 respectively include three sub-areas, which respectively represent the heart rate, the blood oxygen saturation, and the duration of the apnea in order from top to bottom. Of course, the filling order of the heart rate, the blood oxygen saturation, and the duration of the apnea in the three sub-regions is not limited to that shown in fig. 5E, and may be filling in any one of the sub-regions, respectively.
The corresponding display mode can facilitate medical personnel to observe the correlation conditions of different physiological sign parameters.
It should be noted that, as shown in fig. 5C and 5E, the monitoring interface provided in the figure may also mark an apnea triggering time point on the target physiological parameter waveform map and/or mark an apnea event segment on the target physiological parameter waveform map in the manner shown in fig. 5B.
Furthermore, as can be seen from the above description related to fig. 5B to 5F, by adding the physiological sign parameter graphic area to the monitoring interface, the medical staff can intuitively know the real-time variation trend of the physiological sign parameters related to the apnea event occurring in the dedicated display area.
As shown in fig. 5G, in one embodiment, the method of monitoring for apneic events includes displaying a review interface for apneic events or respiratory events in response to user input instructions (e.g., in response to user input instructions through an event list area within the monitoring interface). In other embodiments, the instruction may also be triggered by the user through other touch keys in the monitoring interface or by the user operating a physical key.
The event list area can be accessed to a respiratory event review interface, for example, a user clicks the event list area to pop up the respiratory event review interface, and the review interface contains detailed information of the respiratory event, such as a respiratory oxygenation map.
The medical staff can look back and look over the whole situation of the breathing oxygenation condition of the infant over a period of time through the breathing oxygenation chart. The occurrence distribution of apnea and oxygenation events in the infant patient over a period of time, and the general conditions of bradycardia minima, hypoxemia minima, and duration of apnea are known from the respiratory oxygenation map overview (region 542). Also, the number of apnea and oxygenation events occurring within the time period is counted (block 545). For an event strictly satisfying the definition of apnea, the event is displayed differently from other events in display form, for example, by color (red, yellow), by character thickness, italic no, underline, addition of a logo, and the like. When the healthcare worker needs to view the details of a particular event, and selects an event, the trend and compression waveform for that respiratory event is displayed (region 541), the bradycardia minimum, hypoxemia minimum, and apnea time maximum (region 544), as well as manually labeled information for that event and the measured values of other parameters measured during that event (region 543).
Region 541 shows the stored HR, SpO2 trend plots and respiration waveforms (e.g., impedance respiration compression waveforms) for one apnea event segment length. Region 544 shows the lowest bradycardia (and duration), lowest hypo-saturation (and duration), and duration of apnea detected during this event, and values exceeding the threshold are displayed in a background color or highlighted with color. Region 543 displays the type and trigger time of this event, as well as manually labeled association information for this event and measurements of other parameters during the event (e.g., blood pressure values).
Region 542 displays all apnea and respiration oxygenation events over a period of time. This time period may be set by the user. Each column is an event, the position where the value occurs indicates that the parameter exceeds the threshold, and the most significant value of the parameter is marked. These events have three states and are distinguished by display: apneic events (red), respiratory oxygenation related parameters (yellow), events not including ABD statistics (white). In addition to color, other means of marking may be used to distinguish between these states.
The area 545 displays statistics specifying the number of all types of events over a period of time, not counting events that have been marked as not including ABD statistics. Also, the different states are displayed differently by display.
Region 546 provides functional buttons for a review of the respiratory oxygenation map, including:
1. a review window size is set, for example, to review respiratory events for time intervals of 24 hours, 12 hours, 8 hours, etc.
2. And modifying the manually marked content of the selected event.
3. The cursor is moved in the respiratory oxygenation map event overview region (region 542) to switch to the previous or next event.
It should be noted that fig. 5G only provides one layout manner of the review interface, and in other embodiments, the layout of the review interface may be adjusted as needed, and the specific content displayed in the review interface may also be adjusted as needed.
In one embodiment, the apnea event monitoring method further comprises: responding to an instruction input by a user, and providing a marking interface; and storing the related information of the respiratory events input by the user through the marking interface.
The monitoring interface may provide access to a markup interface, such as a "Mark" icon in fig. 5D and 5, and when the user clicks the Mark icon, the markup interface appears.
The marking interface comprises a respiratory event display area and an associated information area for displaying respiratory event associated information, wherein the respiratory event display area contains at least one piece of respiratory event related information, and the related information comprises an occurrence time point and an event type of a respiratory event. See fig. 6A and 6B, which illustrate one example of a tagging interface provided herein. As shown in fig. 6A, the tagging interface includes a respiratory event presentation area 601 that includes the event point and event type of the respiratory event that occurred within the historical 24 hours. If all respiratory events cannot be displayed in the area at the same time, the respiratory events which are not displayed can be checked in a touch sliding mode. In addition, respiratory events within the region may be presented sequentially with reference to the order of occurrence.
If the healthcare worker needs to enter relevant information for a certain respiratory event, the healthcare worker can click on the respiratory event in the respiratory event display area, as shown in fig. 6A and 6B, assuming that the selected respiratory event is the first, i.e., ABD respiratory event that occurs at 9 points and 30 points.
Clicking on the respiratory event presentation area may generate a set instruction for the target respiratory event. And displaying a related information area based on the setting instruction, wherein the related information area contains optional parameter items of related information of the respiratory event, and the related information is information for assisting in judging the severity of the respiratory event. As shown in fig. 6A, the markup interface includes an associated information area 602, which includes the following contents:
optional parameter items of skin color (skin color) include: reddish (pink), grayish (dusky), cyanotic (cyanotic), mottled (mottled), and jaundice (jaundice);
optional parameter items of the stimulation level (stimulation) include: strong (vigorous), medium (modete), weak (mil), none (none);
optional parameter items of the custom (custom) respectively include: mechanical ventilation (mechanical ventilation) and feeding (feed).
It should be noted that the english concept in fig. 6B has the same meaning as the chinese concept at the position corresponding to fig. 6A.
This information is selected to be recorded as correlation information because the correlation parameters may reflect, to some extent, the severity of the respiratory event.
The selectable item of associated information is used to reflect the condition of the target subject at the time of the occurrence of the target respiratory event. The medical staff can select the corresponding selectable items according to the information of the clinical record at the moment.
After the items selected by the user in the selectable items are obtained, establishing an incidence relation with the corresponding respiratory events; and storing the association relationship in the information related to the respiratory event. The stored content is used as supplementary content of the respiratory event, which is helpful for medical staff to more completely know the overall view of an event.
In addition, the related information area may further include another related information and a selectable item. The correlation information also includes an attribute indicating whether the respiratory event is valid or invalid. The apnea event monitoring method further comprises: invalid respiratory events are excluded from the statistics. As shown in fig. 6A and 6B, namely: statistics of whether to enter an ABD event (count int ABD total): yes or no.
Clinical medical staff pay more attention to the occurrence frequency and the frequency of respiratory events, and frequent respiratory events within a period of time indicate that the condition of a patient is not good and a doctor needs to intervene in time. However, some clinical operations or external disturbances may cause short-time abnormalities of the patient, for example, nursing a child, which may cause respiratory arrest when swallowing, or wiping a diaper or the like, which may cause apnea due to temporary posture problems of the child, and may relieve the risk if a nurse handles the infant in time. If incorporating such a problem into respiratory event statistics does not facilitate the physician in understanding the patient's valuable frequency of occurrence of respiratory events, an option is provided whether to incorporate the event into ABD event statistics. If the selection is yes (i.e., valid), then statistically display in a respiratory event review interface or event list area; if the selection is no (i.e., invalid), then the statistical display in the respiratory event review interface or event list area is not included.
Fig. 6C and 6D show another form of the mark interface, that is, the respiratory event display area only includes the related information of the currently occurring respiratory event, and the related information is set only for the respiratory event. It should be noted that the english concept in fig. 6D has the same meaning as the chinese concept at the position corresponding to fig. 6C. Other contents in the two diagrams can be referred to the description in fig. 6A, and are not described herein.
It should be noted that fig. 6A-6D may further include cancel (cancel) and save (save) buttons, respectively: canceling the marking interface and storing the associated information in the setting area.
In practical application, the content of interest of the medical staff to the physiological sign parameter is the occurrence time point of an apnea event triggered by the physiological sign parameter, and the occurrence time point is visually displayed in the monitoring interface as the content of interest.
Therefore, in an embodiment, at least the time when the duration of the apnea reaches the second duration threshold is also output in the dedicated display area.
An example of a corresponding monitoring interface for this embodiment is shown in fig. 7A. As shown in fig. 7A, the monitoring interface includes a dedicated display area 701, and if the occurrence time of an apnea event is 9 o' clock and 30 minutes, the words "9: 30" and "apnea" are displayed in the dedicated display area. To provide a more striking prompt so that the caregiver can see the prompt at a greater distance, the text can be highlighted and a background color can be added to the text.
See fig. 7B and 7C, which illustrate yet another example of a monitoring interface provided by the present application. For example, as shown in fig. 7B, the monitoring interface may further include a graphic area 712 based on the dedicated display area 711. A graphical region 712 displays a waveform of the physiological sign parameter associated with the apneic event. It should be noted that the english concept in fig. 7C has the same meaning as the chinese concept at the position corresponding to fig. 7B.
Further, the occurrence time points of the apnea events are displayed in the dedicated display area 711, and the most significant value of the physiological parameter is marked in the physiological parameter waveform map in the graphic area 712. For example, as shown in fig. 7B, the lowest value of the heart rate in the event of apnea is labeled 83bpm in the heart rate trend graph, the lowest value of the blood oxygen saturation is labeled 51% in the blood oxygen saturation trend graph, and the maximum value of the duration of apnea is labeled 24 seconds in the compressed respiration waveform graph.
In the illustration shown in fig. 7B, the portion filled with diagonal lines may include a "mark" icon, that is, a "mark" icon shown in fig. 7C. When the user clicks the 'mark' icon, a pop-up mark interface can be triggered, and the related information of the respiratory event can be input according to the operation of the user on the mark interface.
In practical application, if the physiological sign parameter of the target object is restored to the normal range, the attention content in the dedicated display area can be automatically cleared, that is, if the physiological sign parameter is restored to the normal range, the displayed attention content is cleared. In this case, the content of interest indicating that an apnea event has occurred is cleared, and the content of interest indicating that an apnea event has not occurred may be displayed, for example, in the form of "normal".
Alternatively, if the physiological parameters of the target subject return to the normal range, the content of interest in the display area may continue to be displayed until manually cleared by the user. Specifically, in response to a cancel display operation triggered by the user, the displayed content of interest is cleared. The application scenario of this method is that if the medical care personnel finds that the current apnea event is not serious, or processes the current apnea event through a rescue measure, the medical care personnel can manually operate a clear button to delete the concerned content from the dedicated display area.
In another embodiment, the dedicated display area for displaying the attention content may also be closed after the physiological parameters of the target subject return to the normal range, or in response to a window closing instruction manually input by the user.
It should be noted that, regardless of the above-mentioned manner of automatic clearing or manual clearing, if a new apnea event occurs in the target object, the new apnea event will generate a new content of interest, and the new content of interest will replace the previous content of interest in the apnea event. I.e. the dedicated display area shows the content of interest of the last apneic event.
Further, if the monitoring interface associated with respiration is turned off, a notification message may be output if an apnea event is detected in the subject. In one implementation, the notification information is in the specific form of displaying a monitoring interface including a dedicated display area, and displaying the attention content indicating that the apnea event has occurred in the dedicated display area. In another implementation, the notification message is in the form of an audible alarm tone and/or an alarm bar. In yet another implementation, the two implementations described above may be combined for prompting.
In some embodiments, the processor may further perform the steps of:
automatically identifying an apnea triggering time point from real-time data of a target physiological sign parameter;
setting a graphic area in a monitoring interface of a display, and displaying the target physiological sign parameter oscillogram in the graphic area;
the processor performs one of the following steps based on the automatically identified apnea trigger time point:
marking an apnea triggering time point on a target physiological sign parameter oscillogram,
outputting a trigger to display an apnea within the dedicated display area; and the combination of (a) and (b),
and marking the time point of the lowest value occurrence of the target physiological sign parameter on the target physiological sign parameter oscillogram.
For example, in fig. 5F, the apnea trigger time points are marked on the target physiological sign parameter waveform by vertical lines labeled 9: 30. The point in time on the target physiological parameter waveform map at which the labeling of the lowest value of the target physiological parameter occurs is represented in fig. 7B by the position of the labels 83, 51, 24S. The trigger to output a display apnea within the dedicated display area may be characterized in fig. 7B by the indicia 9:30 apnea.
Additionally, in a further embodiment, the event segment containing the apnea trigger time point is also marked on the target physiological sign parameter waveform map. For example, in fig. 5F, the event segment containing the apnea trigger time point marked on the target physiologic parameter waveform map is represented by marking the shaded area containing the 9:30 vertical line.
Or, in a further embodiment, the process of outputting the trigger for displaying the apnea in the dedicated display area includes:
