Background

A respiratory event is an abnormal condition associated with a respiratory state that occurs in a clinical patient. One common respiratory event is apnea. Apnea, which is characterized by the cessation of spontaneous breathing of a patient, may cause more serious injury to the patient if the patient cannot be treated in time. Apnea monitoring is common in the care of newborns. In particular, neonates, especially premature infants, are often accompanied by apnea problems due to insufficient development of the individual organs. The smaller the gestational age of the infant, the higher the rate and frequency of apnea problems. The long-time apnea can cause insufficient oxygen supply of each organ tissue of the infant patient, and the life health of the infant patient is directly threatened. Of course, respiratory events may also include others.

The occurrence of respiratory events over a historical period of time may reflect, to some extent, the respiratory oxygenation status of the patient.

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.

Clinical medical personnel not only monitor whether the respiratory event happens to the patient, but also pay more attention to the occurrence frequency of the respiratory event. Since if the frequency of occurrence becomes high, even if the patient can recover himself, it is possible to indicate that the respiratory oxygenation status of the patient is deteriorating, and it is necessary to perform the treatment as early as possible. If a healthcare worker manually records respiratory events, some patients may miss spontaneous return to normal respiratory events due to the inability to keep guard around the patient all the time, resulting in a significantly fewer number of recorded respiratory events than the number of actual occurrences of the patient.

Thus, the occurrence of respiratory events may be automatically monitored by the medical device and recorded. Medical personnel may review respiratory events that have occurred within a historical period of time for a patient on a medical device to learn the respiratory condition of the patient.

The application provides a retrospective display method of respiratory events, which can be applied to any form of medical monitoring system. A medical monitoring system can be understood as a single medical device, such as a monitor, an invasive ventilator, a non-invasive ventilator, etc.; a system comprising a plurality of medical devices, for example, a system comprising a bedside device and a nurse station/central station, may also be understood. The following embodiments are mainly described by taking a monitor as an example.

Referring to fig. 1, the method specifically comprises steps 1.1-1.4.

Step 1.1: acquiring respiratory events of a target object within a preset time period, wherein the respiratory events at least comprise apnea events; the respiratory event is identified from a signal of at least one physiological parameter acquired by at least one physiological parameter sensor.

The execution of this step may be based on a trigger instruction, for example, a review entity button may be provided on the medical device, and the user may operate the review entity button to generate the trigger instruction, and for example, a review icon is included in a main monitoring interface displayed by the medical device, and the user may touch the review icon to generate the trigger instruction.

And after receiving the triggering instruction, acquiring the respiratory events of the monitored object in a preset time period from the equipment. For convenience of description, the object may be referred to as a target object. The target object may be a neonate or other type of patient. The device for recording respiratory events may be a medical device applying a method for the retrospective display of respiratory events, or may be another device.

The respiratory event represents that the physical sign state related to the respiration is abnormal, and the respiratory event can specifically comprise an apnea event, a respiratory oxygenation event and other specific events. In this step, the acquired respiratory events include at least apneic events.

Apnea events, respiratory oxygenation events 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 attend to them.

The triggering condition is relatively more stringent for apnea events versus respiration oxygenation events, which may be embodied as more physiological parameters being used to trigger events, more physiological parameters being indicative of the severity of a respiratory problem, or more stringent parameter thresholds in the triggering condition.

For example, respiratory events involve three physiological parameters, namely duration of Apnea, blood oxygen saturation, and heart rate, and Apnea (or simply a) may be used to indicate Apnea, Desaturation (or simply D) may be used to indicate hypoxemia, and Bradycardia (or simply B) may be used to indicate Bradycardia associated with heart rate.

The triggering conditions for an apneic event may be: any one of ABD, AB, AD, A, ABDn, ABn, ADn and An, wherein n represents the duration of apnea. For example, a20 indicates a single apnea lasting 20 seconds, and AB15 indicates an apnea lasting 15 seconds with a low heart rate.

The triggering condition for a respiratory oxygenation event may be any of BD, B, D.

It should be noted that what kind of physiological parameters are included in the trigger condition indicates which kind of physiological parameters have values that reach 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.

It can be seen that the triggering condition for the respiratory oxygenation event is more relaxed than the decision condition for the apnea event. Both are events of abnormal breathing state and therefore may be collectively referred to as respiratory events. Respiratory events are states associated with apneas.

The respiratory event is identified from the information of the physiological sign parameters, and how to identify whether the target subject has a respiratory event according to the physiological sign parameters is described first below.

Besides the parameters such as blood pressure, electrocardiogram and body temperature, the physiological parameters at least include physiological parameters related to the apnea state, such as heart rate, pulse rate, blood oxygen related parameters, respiration rate/respiration waveform, and the like, in order to monitor the apnea related state of the target subject. Wherein the apnea duration may be determined from the respiration rate/respiration waveform. It should be noted that the acquired physiological parameters are basic data for determining whether a respiratory event can be triggered. Of course, in other embodiments, it is not excluded that other physiological parameters are taken into consideration when determining the apnea-related condition.

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 may be a physiological sign parameter stored in the storage module of the medical device by the sensor, and the physiological sign parameter is obtained from the storage module. Of course, the physiological parameters can also be obtained directly from the sensors.

After obtaining the physiological sign parameters, according to each determination standard (or called trigger condition, judgment condition) of the respiratory event, whether the physiological sign parameters meet a certain determination standard is judged, and if the physiological sign parameters meet the certain determination standard, the respiratory event corresponding to the determination standard is shown to occur. An apnea event is exemplified.

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 (or pulse rate, since the pulse rate and the heart rate usually represent the same physiological status, the heart rate is mainly used for illustration in this embodiment) are taken 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 apnea event may include three parameters, namely, the duration of apnea, the blood oxygen saturation value, and the heart rate, and these physiological parameters have respective corresponding thresholds, and when one or more of the parameters reaches the above-mentioned decision condition, the apnea event is indicated to occur. The above is only a specific identification criterion, and in practical applications, any one of the above-mentioned determination conditions may be used.

Step 1.2: determining an event type marker for the respiratory event, the event type marker representing a type of a corresponding physiological sign parameter that triggered the respiratory event.

In one embodiment, the manner in which event type indicia of respiratory events are determined includes: obtaining physiological sign parameters of a target subject related to respiration, and analyzing whether the physiological sign parameters can trigger a respiratory event, wherein the respiratory event comprises an apnea event or a respiratory oxygenation event; if yes, determining a target physiological sign parameter for triggering the respiratory event in the physiological sign parameters, and determining the type of the respiratory event based on the target physiological sign parameter.

That is, which physiological sign parameter or parameters are included in the trigger condition indicates that the value of the physiological sign parameter or parameters reaches the corresponding parameter threshold. The target physiological sign parameter is the physiological sign parameter contained in the trigger condition that is met, which may determine the event type of the respiratory event.

For example, in the physiological sign parameters of the target subject, if the apnea duration a and the heart rate B simultaneously satisfy the trigger condition, the target physiological sign parameter is the two physiological sign parameters, and the event type of the respiratory event is determined as AB. For another example, in the physiological sign parameters of the target subject, if the apnea duration a and the blood oxygen saturation level D simultaneously satisfy the trigger condition, the target physiological sign parameter is the two physiological sign parameters, and the event type of the respiratory event is determined as AD. For another example, if the blood oxygen saturation level D in the physiological sign parameters of the target object satisfies the trigger condition, the target physiological sign parameter is the physiological sign parameter, and the event type of the respiratory event is determined as D.

Specifically, the type of the respiratory event is distinguished 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.

The determined type of respiratory event may be indicated using an event type flag, which may be referred to as event type for short, so in this application the event type flag has the same meaning as event type.

The event type may be considered an attribute of the respiratory event. When a respiratory event is recorded, the time point of occurrence of the respiratory event may also be recorded. Step 1.1 may obtain respiratory events occurring within a preset time period according to the occurrence time point. The preset time period may be a historical period of time from the current point in time, such as respiratory events over the past 24 hours. The acquisition of a respiratory event may be one or more.

Step 1.3: a respiratory event review interface is provided in the primary monitoring interface, the respiratory event review interface including an event display area.

In some embodiments, the respiratory event review interface may be a fixed sub-region in the main monitoring interface, that is, the respiratory event review interface is embedded in the main monitoring interface, is displayed following the display of the main monitoring interface, and disappears following the disappearance of the main monitoring interface.

In some embodiments, the respiratory event review interface is openable and closable. Specifically, a respiratory event review interface pops up in the main monitoring interface in response to a triggering instruction input by the user. A pop-up respiratory event review interface can be suspended on the main monitoring interface, and the respiratory event review interface in this form can cover information in the main monitoring interface as a background; or the respiratory event review interface may be embedded in the main monitoring interface in a form that is ejected and embedded in the main monitoring interface, and other information in the main monitoring interface may disappear or may be rearranged. That is, the respiratory event review interface may be the entire display interface of the medical device display, or may be one display window embedded or floating on the entire display interface of the medical device display.

The respiratory event review interface comprises an event display area, and the position attribute, the shape attribute, the display attribute, the state attribute and the like of the event display area can be adjusted. For example, the location attribute of the event display area refers to the display location of the event display area on the primary respiratory event review interface; the shape attribute of the event display area includes the style, size and the like of the shape, for example, the shape may be various, such as rectangle, circle, heart and the like; the display attribute of the event display area refers to attribute information such as color, brightness, contrast and the like of all or part of the display area; the status attributes of the event display area include visible or invisible attributes, an embedded respiratory event review interface or hover over respiratory event review interface, and the like.

In some embodiments, the event display area may be displayed following the display of the respiratory event review interface, disappearing following the disappearance of the respiratory event review interface. Alternatively, in some embodiments, the event display area further has separate on and off control buttons, and when the on button is triggered, the state attribute of the event display area can be switched so that the event display area is displayed at a certain position of the respiratory event review interface, and when the off button is triggered, the state attribute of the event display area can be switched so that the event display area disappears from the respiratory event review interface. It should be noted that the event display area does not limit the position of the area in the respiratory event review interface to be fixed, and may be movable, for example, the position attribute of the event display area may be adjusted according to the sliding track of the touch operation, so that the display of the event display area may move along with the touch operation.

Step 1.4: and outputting and displaying a time axis determined based on the preset time period in the event display area, and displaying the respiratory event corresponding to the time axis based on the event type mark.

The acquired respiratory events occurring within the preset time period need to be displayed in a display mode for medical staff to check. In some embodiments, a statistical chart having a time axis is generated in the event display area, and respiratory events are displayed within the statistical chart. The time axis corresponds to a preset period of time during which a respiratory event is acquired, e.g., the acquired respiratory event occurred within the past 24 hours, and the time axis includes a length of time of 24 hours.

In one embodiment, the time axis may be plotted as the abscissa of the statistical chart, and the respiratory events are displayed on the ordinate of the chart. Displaying the respiratory event in particular, an event type marker of the respiratory event is displayed at the ordinate.

The respiratory event can have an occurrence time point attribute on the basis of the event type mark attribute, and the occurrence time point of the respiratory event can be obtained when the respiratory event is obtained. Therefore, the process of displaying the respiratory event corresponding to the time axis based on the event type mark specifically includes obtaining an occurrence time point of the respiratory event and an event type mark of the respiratory event; in a relation chart of the time and the event type mark, an abscissa corresponding to the occurrence time point is determined, and the event type mark is prompted at a position of a ordinate corresponding to the abscissa.

As can be seen from the above description of the event type flag, the event type flag is determined by the physiological parameters causing the respiratory event, and therefore, the value of the physiological parameters causing the respiratory event can be displayed at the same time as the event type flag is displayed. For example, a tile filled with a background color is displayed at the ordinate position. From which vertical coordinates corresponding to the horizontal coordinates of a time point contain blocks, which physiological sign parameters are associated with a respiratory event can be determined, and further an event type mark of the respiratory event is determined; at the same time, the corresponding values of the physiological parameters that trigger the respiratory event can be displayed in the blocks.

It should be noted that the time axis mentioned in the present application is not limited to the scheme of displaying a time axis in the display interface, and also includes other schemes capable of providing time information. For example, a scheme of providing time information through a time list; or a scheme in which even though the time information is not displayed in the display interface, a person of ordinary skill in the art can obtain the time information through the displayed contents.

See FIG. 2A, which shows one example of an event display area. As shown in fig. 2A, the event display area includes a relation chart area 201, which includes a relation chart of time and physiological parameters, wherein the abscissa is a time axis, and the ordinate includes three physiological parameters, which are an apnea duration a, a blood oxygen saturation level D, and a heart rate B. The hatched portion in fig. 2A may be filled with other information related to breathing or may be empty.

As can be seen from the diagram, there are blocks filled with background colors at about-18 h (hour), -15h, -12h, -8h and-4 h of the abscissa, wherein three blocks at the abscissa point of-18 h correspond to the physiological sign parameters A, B and D, respectively, three blocks at the abscissa point of-15 h correspond to the physiological sign parameters a and D, respectively, three blocks at the abscissa point of-12 h correspond to the physiological sign parameters B and D, respectively, three blocks at the abscissa point of-8 h correspond to the physiological sign parameter D, and three blocks at the abscissa point of-4 h correspond to the physiological sign parameters a and B, respectively. Of course, time in the abscissa can also be expressed as a specific time point, for example, 5 time points from 2018.7.20 to 2018.7.21: 8:00, 12:00, 16:00, 20:00, 00:00, 4: 00.

It can thus be determined that the graph lists 5 respiratory events that occurred within the historical 24 hours. The respiratory events that occurred before 18, 15, 12, 8, 4 hours were ABD, AD, BD, D, and AB, respectively.

According to the technical scheme, the respiratory event retrospective display method provided by the application can obtain the respiratory event of the monitored object in the historical time period, determine the event type mark of the respiratory event, and further display the respiratory event in the historical time period in the event display area of the respiratory event retrospective interface based on the event type mark. Medical personnel can know the respiratory event occurrence frequency, the severity and other related information of the monitored object by looking up the event display area, and then know the respiratory condition of the monitored object.

In some embodiments, since respiratory events may include apneic events and respiratory oxygenation events, which indicate different levels of severity of respiratory problems, different types of respiratory events may be distinguished by different display patterns in order to explicitly prompt the healthcare worker as to which type of respiratory event occurs.

In particular, the apneic event is displayed in a first display style and the respiratory oxygenation event is displayed in a second display style distinct from the first display style. In some embodiments, the display pattern may be specific to a block color of the respiratory event. For example, the background color of the blocks for apnea events is darker than the background color of the blocks for respiratory oxygenation events.

Taking the five respiratory events of fig. 2A as an example, the apnea events can include the respiratory events ABD, AD, and AB, and the respiratory oxygenation events can include the respiratory events BD and D, as defined above. Thus, the block background color of the first three respiratory events may be darker than the second two respiratory events. Still further, certain respiratory events of respiratory oxygenation events may be flagged by healthcare personnel as non-statistical respiratory events that are not incorporated into the statistics of respiratory events. Therefore, the respiratory events can be based on the apnea events and the respiratory oxygenation events and can also comprise nonstoichiometric respiratory events, and the three types of respiratory events are displayed by using three different styles. As shown in FIG. 2A, the non-statistical respiratory event is respiratory event D, which is displayed in white.

It should be noted that the blocks for prompting respiratory events may not be limited to square, but may be in other shapes, and further, the prompting manner is not limited to blocks, and may be in other forms such as icons, characters, and the like. The method of distinguishing respiratory events of different classifications is not limited to the background color of the block, and when the physiological parameters are represented by characters, the characters may be thick and thick, italic, underlined, or with a logo.

In practical application, if a respiratory event occurs in a target object, the monitoring device can record the respiratory event, and also record the attention data of physiological sign parameters related to the respiratory event. The data of interest is information related to respiratory events that are of interest to the medical staff, and for ease of understanding, the data of interest will be explained first.

The data of interest is used to indicate the severity of the respiratory event. It should be noted that the data of interest reflects the severity of the respiratory event objectively and meets the objective cognitive standard of people. For example, in a respiratory event, objective cognition considers the respiratory event to be more severe if the heart rate of the target subject is lower, and thus the data of interest may include the lowest value of the heart rate in the event segment. As another example, in a respiratory event, if the target subject's blood oxygen saturation value is lower, the respiratory event is considered to be more serious in objective cognition, and thus the attention data may include the lowest value of the blood oxygen saturation values in the event segment. As another example, in a respiratory event, if the target subject has a longer apnea duration, the respiratory event is also considered objectively more severe, and thus the data of interest may include a maximum value of the apnea duration in the event segment.

In some embodiments, the data of interest is the most significant value of the physiological sign parameter associated with the respiratory event.

In order to obtain the maximum value of each physiological sign parameter, a statistical time duration needs to be set, the obtained value in the limited time duration is limited, and the maximum value of the physiological sign parameter can be determined in the limited data. The length of the statistical time period may be preset, such as 4 minutes. It should be noted that a period of time including the length of the statistical time period of the occurrence time point of the apnea event may be referred to as a monitoring time interval or an event segment.

When determining the maximum value for the apnea duration, the individual apnea durations within the event segment are compared to determine the maximum value. Similarly, the lowest value of the blood oxygen saturation value, the lowest value of the heart rate and the lowest value of the pulse rate can be determined. In other embodiments, the physiological parameters for which the data is focused are not limited to the above parameters, but may be other parameters such as perfusion index.

And after the attention data of the physiological sign parameters are determined, displaying the attention data at the relative position of the time axis of the respiratory event. Specifically, according to the occurrence time point of the respiratory event, the abscissa position of the occurrence time point on the time axis is determined, and the attention data of the physiological sign parameters is prompted at the ordinate position of the physiological sign parameters corresponding to the abscissa.

The data of interest for the physiological sign parameter can be displayed in association with an event type marker for the respiratory event, e.g., the event type marker is represented as a block, and the data of interest for the physiological sign parameter is populated as a numerical value within the block.

As shown in fig. 2A, the data of interest of the respiratory event ABD, which are respectively the maximum duration of the apnea duration 23s (seconds), the minimum value of the blood oxygen saturation 60%, and the minimum value of the heart rate 78bpm (beats per minute), are filled in the blocks of the corresponding event type markers A, B and D, respectively. The data of interest of the respiratory event AD are respectively the maximum duration of the apnea duration 12s and the minimum value of the blood oxygen saturation 68%, and these data of interest are respectively filled in the blocks of the corresponding event type flags a and D. The data of interest of the respiratory event BD, which are filled in the blocks of the corresponding event type flags B and D, are the lowest value of the blood oxygen saturation of 77% and the lowest value of the heart rate of 70bpm, respectively. The data of interest for respiratory event D, which is filled in the corresponding block of event type flag D, is the lowest value of 64% of blood oxygen saturation. The data of interest of the respiratory event AB are respectively the maximum duration 23s of the apnea duration and the heart rate minimum 82bpm, and these data of interest are filled in the blocks of the corresponding event type markers a and B, respectively. In some descriptions, the values of blood oxygen saturation and heart rate are not added in units, but it should be noted that the value of blood oxygen saturation is in units, and the value of heart rate is in units of bpm.

Similar to the distinguishing mode of different types of respiratory events, the attention data of different types of respiratory events can be distinguished through the display mode. For example, the display style may include, but is not limited to, font color, font weight, whether to italics, whether to underline, whether to add a markup symbol, and the like.

According to the technical scheme, when the respiratory events are displayed in the statistical chart, the concerned data of the respiratory event sign state parameters can be displayed at the same time. The medical staff can know the occurrence time point, the occurrence frequency and other information of the respiratory events within a period of historical time, and can also know the worst state of each physiological sign parameter when each respiratory event occurs, thereby knowing the severity of the respiratory event.

After the statistical results of the respiratory events are displayed for the user, the user can select a certain respiratory event to view the detailed information of the respiratory event.

Specifically, responding to a selected operation of the respiratory event displayed on the respiratory event review interface, and obtaining physiological sign parameters related to the selected respiratory event; and displaying at least a oscillogram and/or attention data of the physiological sign parameters of the selected respiratory event in a single event display area of the respiratory event review interface.

The selection operation may be embodied in an event display area of the respiratory event review interface, for example, a user may select a respiratory event displayed in the event display area.

Based on the selection instruction of the user, the related information of the physiological sign parameter related to the respiratory event selected by the user can be displayed in the single-event display area. The related information may include a waveform of the physiological sign parameter, such as one or more of a respiratory waveform of the selected respiratory event, a blood oxygen saturation trend graph, a heart rate trend graph, and a pulse rate trend graph. Alternatively, the related information may include data of interest for the physiological sign parameter, such as including one or more of a maximum apnea duration, a minimum blood oxygen saturation, a minimum heart rate, and a minimum pulse rate for the selected respiratory event. Alternatively, the related information may include both of the above contents.

See fig. 2B, which shows another example of a respiratory event review interface. As shown in fig. 2B, the respiratory event review interface may further include a single event presentation area 212 on the basis of the inclusion relationship chart area 211. A respiratory event may be selected when the healthcare worker needs to view details of the respiratory event.

Assuming that the healthcare worker selects a respiratory event that occurred before 18h, as shown in fig. 2B, the selected respiratory event is outlined by the solid line, in the single event display area 212, a respiration (Resp) waveform diagram, a heart rate (btbHR) trend diagram, and a blood oxygen saturation (SpO2) trend diagram for the respiratory event are displayed, and a maximum value of the duration of an apnea (apnea), a minimum value of the heart rate, and a minimum value of the blood oxygen saturation are displayed. As shown in fig. 2B, the trend graph may also use a dashed line to indicate the alarm threshold of the physiological sign parameter, such as the alarm threshold of heart rate is 100, and the alarm threshold of blood oxygen saturation is 80.

Wherein the heart rate floor also corresponds to a floor of a bradycardia (bradycardia) event and the blood oxygen saturation floor corresponds to a limit for a hypo-saturation event. As shown in fig. 2B, the trend graph is a trend graph within 4 minutes. Additionally, the respiration waveform map may be an impedance respiration compression waveform map.

Further, besides the information related to the physiological sign parameters of the respiratory event, the information related to the respiratory event can also be displayed. The association information may be information entered by the healthcare worker through the following tagging interface, which is stored as an attribute of the respiratory event. The associated information is some external condition of the target object when the respiratory event occurs, and the condition can help medical staff to know the serious condition of the respiratory event occurring in the target object.

For example, the associated information may include skin color, irritation level, customization; among these, the skin color may be: reddish, grey, dark purple, blotch, and jaundice; the degree of irritation may be: any one of strong, medium, weak and none; the customization may be: mechanical ventilation and feeding.

Medical personnel can carry out clinical observation when respiratory events occur and record associated information according to the clinical observation. And when displaying, displaying the recorded associated information in the single event display area. As shown in fig. 2B, the displayed related information includes that the skin color (skin color) is pink (ping) and the stimulation degree (stimulation) is weak (mil). Wherein the stimulation level represents the stimulation action that the medical staff applies to the patient in order to relieve the apnea state of the patient.

In addition, the related information may also include some other physiological sign parameters related to the respiratory state, as shown in fig. 2B, and may also include a non-invasive blood pressure (NIBP) of 115/90 (101). Furthermore, the related information may further include a recording time point of the related information, as shown in fig. 2B, the recording time point of the piece of related information is 09: 32. Furthermore, the related information may further include the event type and the occurrence time point of the selected respiratory event, as shown in fig. 2B, the event type of the selected respiratory event is ABD, and the occurrence time point is 9: 30.

It should be noted that, if the selected respiratory event is switched in the relationship chart area 211, the single event display area 212 is switched to the related information and the associated information of the physiological sign parameters of other respiratory events. The positional relationship between the relationship chart area 211 and the single event display area 212 is not limited to the upper and lower sides, and may be the left and right sides.

In addition to fig. 2A using blocks to represent physiological parameters of respiratory events, the present application also provides a way to use short lines with marked points for representation.

See fig. 2C, which shows yet another example of a respiratory event review interface. As shown in fig. 2C, the respiratory event review interface includes a graph area 221, which includes a graph of the relationship between time and physiological parameters, wherein the abscissa is a time axis, and the ordinate includes three physiological parameters, namely, Heart Rate (HR), blood oxygen saturation (SpO2), and Apnea (Apnea).

Each physiological sign parameter has a respective corresponding threshold, which may be represented using a dashed line, as shown in fig. 2C. For example, a heart rate of 100bpm is a threshold scale, and when the heart rate is below 100, a respiratory event is triggered, 80bpm in the illustration being only a portion of the scale, in order to facilitate reading of the specific heart rate floor; 80% of SpO2 is a threshold scale, and when SpO2 is below 80% a respiratory event is triggered, 50% of the graph is only a portion of the scale, to facilitate reading of the lowest value of SpO 2; the apnea 10s is a threshold scale, and when the apnea duration exceeds 10s, a respiratory event is triggered.

As shown in fig. 2C, a group of short lines at each time point constitutes a respiratory event, and specifically, if the physiological parameter of the heart rate is included in the respiratory event, a short line extends downwards from the top of the region of the heart rate, and the short line corresponding to the blood oxygen saturation and the apnea is the same. The top end of each short line contains a dot, and the numerical value of the ordinate corresponding to the position of the dot is the concerned data of the respiratory event. It should be noted that the short line with the mark point may be replaced by only a short line or only a mark point. The mark point can be a circular point, and can also be various shapes such as a triangle, a square box and the like.

In one implementation, the focus data may be displayed directly at a location near the dots. In another implementation, the user may select a particular respiratory event and display data of interest for the physiological sign parameter in the single event presentation area.

See fig. 2D, which shows yet another example of a respiratory event review interface. As shown in fig. 2D, the respiratory event review interface includes a relationship chart area 231 and a single event display area 232. The graph area 231 contains seven respiratory events represented by short line groups. Assuming that the third respiratory event from left to right is selected, in the single event presentation area 232, data of interest of the physiological sign parameter of the respiratory event, namely the lowest value of the heart rate (Bradycardia) is 60 and is below the set threshold value for 14s (seconds), is displayed; the minimum value of blood oxygen saturation (Desaturation) is 78; the length of the Apnea (Apnea) is 23 seconds maximum.

It should be noted that, in order to make an obvious prompt, a preset display mode with a prominent effect may be used for the data of interest of the physiological sign parameters, for example, the data of interest may be displayed in a background color in a reversed color, or in a differentiated color.

The single event presentation area 232 includes association information on the upper side of the relationship icon area 231 and the most valued area on the right side.

In addition, as shown in fig. 2D, the time points of occurrence 9:30 may also be displayed next to the short lines of the selected respiratory events.

As can be seen from the above descriptions of fig. 2B and fig. 2D, for the selected respiratory event, the physiological sign parameters associated with the selected respiratory event, such as the trend graph of the physiological sign parameters and/or the maximum value of the physiological sign parameters, can be displayed in the single event display area of the respiratory event review interface. Furthermore, the related information of the respiratory events entered by the medical personnel can be displayed.

In practical applications, the analyzing of the respiratory events may further include counting the number of occurrences of the respiratory events within a preset time period according to the event type flag.

It should be noted that, in the statistical process, in addition to determining whether the respiratory event is within the preset time period, it may also be determined whether the respiratory event has a flag that does not include the statistics, and if the respiratory event occurs within the preset time period but has the flag that does not include the statistics, the respiratory event may not be counted.

The reason for such statistics is that although some respiratory events are judged as respiratory events by the device, the medical staff observes the condition of the target subject and finds that the respiratory events may be caused by reasons other than the health condition of the target subject, such as the respiratory events caused by the feeding operation of the infant by the medical staff. Since the statistical result can be used as a basis for medical staff to judge the respiratory state of the target object, if the respiratory events caused by these unexpected reasons are included in the statistics, the judgment result will be affected. Thus, the respiratory event may be flagged by the healthcare worker and the flagged result may be stored as an attribute of the respiratory event. And when counting, determining whether the respiratory events are included in the statistics according to the attribute.

A count area is provided in the primary monitoring interface in which the number of occurrences of respiratory events may be displayed. The display mode of the count statistics area in the main monitoring interface can be referred to as a respiratory event review interface, and is not described herein. In addition, the count area may be used as an area in the main monitoring interface or as an area in the respiratory event review interface.

See fig. 2E, which shows yet another example of a respiratory event review interface.

As shown in fig. 2E, the respiratory event review interface may further include a number statistics area 243 based on the inclusion relationship chart area 241 and the single event display area 242. The number statistics area 243 displays: a total of 10 respiratory events occur over 24 hours, and these respiratory events are divided into eight types, of which: respiratory event ABD occurred 1 time, respiratory event AB occurred 1 time, respiratory event AD occurred 1 time, respiratory event a20 occurred 1 time, respiratory event a10 occurred 3 times, respiratory event BD occurred 1 time, respiratory event B occurred 1 time, and respiratory event D occurred 1 time.

Wherein, the respiratory event a20 indicates that the alarm threshold of the apnea duration is 20 seconds, and the occurrence of the respiratory event indicates that the apnea duration of the target object exceeds 20 seconds; respiratory event a10 indicates an apnea duration alarm threshold of 10 seconds, and the occurrence of the respiratory event indicates that the target subject's apnea duration exceeds 10 seconds.

It should be noted that, in the same manner as the display of the respiratory events in the relational chart area, the respiratory events may be displayed in a differentiated manner according to their classification. In addition, the count area may not be displayed in conjunction with other areas, but may be displayed separately in the respiratory event review interface.

In clinical observation, the statistics of certain physiological sign parameters have certain guiding significance for analyzing the respiratory state of a target object. These physiological sign parameters may be any of those mentioned herein. Therefore, the statistical result of the physiological sign parameter can be displayed in the main monitoring interface.

Specifically, obtaining a historical value of at least one physiological sign parameter of the target subject within the preset time length; performing distribution statistics on the historical values based on at least one parameter partition, and determining distribution statistics corresponding to the parameter partition; the parameter partition represents a numerical interval of the physiological sign parameter; and providing a subsection statistical area on the main monitoring interface, and displaying the distribution statistical result in the subsection statistical area.

Wherein, the distribution statistical result is: and the physiological sign parameters respectively fall into the number or the number ratio of the parameter partitions in historical values within a preset time length.

The statistical result can be displayed in a text form or in an image distribution statistical chart form for convenient viewing. Therefore, a distribution statistics chart is generated in the main monitoring interface based on the parameter partition and the distribution statistics. In some embodiments, the distribution statistics graph is a histogram with the parameter partitions and the distribution statistics as two coordinate axes, respectively. For example, the parameter distribution is taken as the abscissa of the histogram, and the distribution statistical result is taken as the ordinate of the histogram.

It should be noted that any one or more of the number of the physiological sign parameters displayed in the segmented statistical region, the type of the physiological sign parameters, and the preset time length corresponding to the historical value may be set by the user. Specifically, a selection window may be provided in the segmented statistical region, and a user may input a selection instruction through the selection window, where the selection instruction represents selection of a target physiological parameter of interest to the user and a preset time length corresponding to a historical value of the target physiological parameter. And further, responding to a selection instruction input by the user, and displaying a distribution statistical result of the historical value of the target physiological sign parameter selected by the user in the segmented statistical area. Of course, the mode of inputting the selection instruction by the user is not limited to the virtual selection window provided by the interface, and an entity button may be provided in the monitor for the user to select the setting.

In the embodiment of the present application, it is assumed that the target physiological sign parameter selected by the user is the blood oxygen saturation level, and the physiological sign parameter is taken as an example to be described below.

Obtaining various historical values of the blood oxygen saturation degree of the target object in a preset time period; determining the blood oxygen saturation degree subarea to which each historical value belongs; and counting the ratio between the number of the historical values in each blood oxygen saturation partition and the total number of the historical values, and displaying the ratio. Wherein, one blood oxygen saturation part is a partial interval between [ 0-100% ], and a plurality of blood oxygen saturation parts are combined to be a whole interval of [ 0-100% ].

See fig. 2F, which shows yet another example of a respiratory event review display method. As shown in fig. 2F, the respiratory event review interface may further include a segmented statistics area 254 based on the inclusion relationship chart area 251, the single event display area 252, and the number statistics area 253. The segmented statistic region 254 includes four blood oxygen saturation regions, which are [ 0-80% ], [ 81% ] -90% ], [ 91% ] -95% ], and [ 96% ] -100% ]. The blood oxygen statistics (SpO2 static) of the target subject over the past 24 hours (h) are: the amount of the blood oxygen saturation value is less than 80% of the total amount and is 5%, the amount of the blood oxygen saturation value is more than 81% and less than 90% of the total amount and is 15%, the amount of the blood oxygen saturation value is more than 91% and less than 95% of the total amount and is 70%, and the amount of the blood oxygen saturation value is more than 96% and less than 100% of the total amount and is 10%.

The segmented statistical region may include a plurality of parameter partitions, and one parameter partition(s) may have a special meaning with respect to other parameter partitions. The special significance can be specifically that the method can provide guidance significance for medical care personnel to judge the health state of the monitored object. For convenience of description, a parameter partition having such a special meaning may be referred to as a target parameter partition. The target parameter partition may be a parameter partition corresponding to a normal condition, or may be a parameter partition corresponding to an abnormal condition, or may be a parameter partition which is desired to be achieved after treatment by a medical means. The target parameter partition is specifically which parameter partition or partitions, and may be preset by the system, or may be set by a user through selection.

In order to distinguish the target parameter partition, a display style different from other parameter partitions may be used to display the target parameter partition and/or the distribution statistical result corresponding to the target parameter partition.

Taking the oximeter as an example, the statistical interval corresponding to the normal condition is displayed in a differentiated manner, as shown in fig. 2F, if the statistical interval corresponding to the normal condition is [ 91% ] -95% ], the statistical interval is filled with the background color. Of course, the manner of display is not limited to color, and may be differentiated by adding an icon or the like.

See fig. 2G and 2H, which show yet another example of a respiratory event review interface. It should be noted that the two diagrams show the same example, except that the english concept used in fig. 2H is shown in fig. 2G in chinese. The layout of fig. 2G will be mainly described below, and the same principle as that of fig. 2H will be understood.

As shown in fig. 2G, the respiratory event review interface includes a function button area 264 based on a relationship chart area 261, a single event display area 262, and a number statistics area 263. Note that, the description of the relationship chart area 261, the single event display area 262, and the number statistics area 263 can be referred to above, and only the function button area 264 is described below.

The function button area 264 includes a window selection sub-area, in which a review duration, that is, a preset time period mentioned in the present application, can be selected. As shown in fig. 2G, the preset time period may be selected to be 24 hours, but other values may be selected, such as 12 hours, 8 hours, etc. It should be noted that the set time period may be used as the length of the preset time period in step 1.1, may also be used as the length of a time coordinate axis in a relation chart, may also be used as a time period for counting the occurrence frequency of respiratory events, may also be used as a preset time period in blood oxygen statistics, and the like.

The function button area 264 also contains a mark (mark) button that can be clicked on to pop up a mark interface if a respiratory event is selected. The marking interface comprises the related information of the respiratory event, and the related information of the respiratory event can be modified in the marking interface, such as modifying the skin color related to the respiratory event.

As shown in fig. 3A-3D, a schematic view of a marking interface is shown. The method for retrospective display of respiratory events 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.

In an embodiment, the tagging interface includes a respiratory event presentation area 301 and an associated information area 302 for displaying respiratory event associated information, and the method for displaying a review of respiratory events further includes: displaying relevant information corresponding to the selected respiratory event in a relevant information area of a marking interface according to the respiratory event selected by a user in a respiratory event display area; and stores the associated information input by the user through the associated information area of the markup interface.

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 of a respiratory event and an event type mark. See fig. 3A and 3B, which illustrate one example of a tagging interface provided herein. As shown in fig. 3A, the tagging interface includes a respiratory event presentation area 301 that includes event points and event type tags for respiratory events that occurred within a historical 24-hour period. 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. 3A and 3B, 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 tagging interface includes an associated information area 302, 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. 3B has the same meaning as the chinese concept at the corresponding position in fig. 3A.

This information is selected to be recorded as correlation information because the correlation information 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 statistical results, for example, excluded from the time axis of the time display region, excluded from the segment statistics, excluded from the count, and the like. As shown in fig. 3A and 3B, 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.

Referring to fig. 3C and 3D, another form of the mark interface is shown, 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. 3D has the same meaning as the chinese concept at the position corresponding to fig. 3C. Other contents in the two diagrams can be referred to the description in fig. 3A, and are not described herein.

It should be noted that fig. 3A-3D may further include cancel (cancel) and save (save) buttons, respectively: canceling the marking interface and storing the associated information in the setting area.

The function button region 264 further includes a left-shift cursor "<" and a right-shift cursor ">", and respiratory events can be switched and selected in the relationship chart region by touching the two cursors.

See fig. 2I and 2J, which show yet another example of a respiratory event review interface. It should be noted that the two diagrams show the same example, except that the english concept used in fig. 2J is shown in fig. 2I in chinese. The layout of fig. 2I will be mainly described below, and the same principle as described with reference to fig. 2J will be understood.

As shown in fig. 2G, the respiratory event review interface includes a function button region 275 on the basis of a relationship chart region 271, a single event display region 272, a number statistics region 273, and a segment statistics region 274. Note that, the description of the relationship chart region 271, the single event display region 272, the number statistics region 273, and the segment statistics region 274 may be referred to above, and only the function key region 275 will be described below.

The function key region 264 may further include, in addition to a (window) window selection sub-region, a mark (mark) button, a left shift cursor "<" and a right shift cursor ">: a screen button and a detail button.

Upon clicking the detail button, the single event presentation area shown in fig. 4A and 4B may appear. For the description of the region, see above, it is not repeated here. It should be noted that the two diagrams show the same example, except that the english concept used in fig. 4B is shown in chinese in fig. 4A.

After clicking the filter button, a filter interface as shown in fig. 5 may appear, where the filter interface includes multiple types of respiratory events, and the user may select some types of respiratory events. As shown in fig. 5, the selected type may be filled with a background color. The selected event type indicia may serve as the event type indicia for the respiratory events displayed in the relational chart area, that is, the respiratory events displayed in the relational chart area according to the selected event type indicia.

Based on the above-mentioned screening button, a specific implementation manner of obtaining at least one respiratory event that occurs in the target object within the preset time period is as follows: obtaining a target event type mark input by a user; and selecting a respiratory event which occurs in a preset time period by the target object and corresponds to the target event type mark according to the target event type mark. After analysis of the selected respiratory event, the analysis results are displayed in a respiratory event review interface.

The front-end signal processor can be realized by adopting a singlechip or other semiconductor devices. The front-end signal processor may be powered by an isolated power supply, and the sampled data may be sent to the host processor via an isolated communication interface after being simply processed and packaged, e.g., the front-end signal processor circuit may be coupled to the host processor 715 via the isolated power supply and communication interface 714.

The reason that the front-end signal processor is supplied with power by the isolation power supply is that the DC/DC power supply is isolated by the transformer, which plays a role in isolating the patient from the power supply equipment, and mainly aims at: 1. isolating the patient, and floating the application part through an isolation transformer to ensure that the leakage current of the patient is small enough; 2. the voltage or energy when defibrillation or electrotome is applied is prevented from influencing board cards and devices of intermediate circuits such as a main control board and the like (guaranteed by creepage distance and electric clearance).

The main processor performs calculation of the physiological parameters and transmits the calculation results and waveforms of the parameters to a host (such as a host with a display, a PC, a central station, etc.) through an external communication and power interface 716, which may be one or a combination of an Ethernet (Ethernet), a Token Ring (Token Ring), a Token Bus (Token Bus), and a local area network interface (local area network) composed of a backbone Fiber Distributed Data Interface (FDDI) as these three networks, one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, or one or a combination of wired data connection interfaces such as RS232, USB, etc.

The external communication and power interface 716 may also be one or a combination of a wireless data transmission interface and a wired data transmission interface. The host can be any computer equipment of a monitor, an electrocardiograph, an ultrasonic diagnostic apparatus, a computer and the like, and matched software is installed, so that the medical equipment can be formed. The host can also be communication equipment such as a mobile phone, and the parameter processing module sends data to the mobile phone supporting Bluetooth communication through the Bluetooth interface to realize remote transmission of the data.
