Description

Monitoring equipment and setting and guiding method of alarm threshold thereof

Technical Field

The application relates to the technical field of monitoring equipment, in particular to monitoring equipment and a setting and guiding method for an alarm threshold value of the monitoring equipment.

Background

The monitoring device is connected with the patient and is used for monitoring physiological parameters of the patient, in the use process of the monitoring device, medical staff can judge the range of normal values of all parameters according to clinical study statistics and clinical experience to preset parameter alarm thresholds, and when the measured value of the patient parameter exceeds the preset alarm threshold, the monitoring device can generate an alarm to prompt the medical staff that the patient possibly has abnormal physiological states. However, due to differences in vital sign status and therapeutic measures of patients, the measured values of physiological parameters may be very different between patients, for example, the patient base heart rate is relatively high, exceeding 120bpm; or performing heart rate lowering medication on the patient so that the heart rate of the patient is less than 50bpm; these can result in the patient physiological parameter measurement exceeding a preset parameter alarm threshold range, thereby generating a large number of parameter alarms. But these alarms are not of clinical interest and are nonsensical alarms. Excessive nonsensical alarms can cause alarm fatigue problems, delay the response of medical staff to the alarms, disturb the judgment of the medical staff on the state of a patient, lead the alarms which truly need to take clinical intervention measures to be not responded in time, seriously threaten the safety of the patient and reduce the monitoring quality.

While existing monitoring devices generally support healthcare personnel to set specific alarm threshold ranges for different patients, there are still problems with this. Firstly, the monitor cannot automatically suggest to remind medical staff to adjust the threshold, but the medical staff is passively changed after excessive meaningless alarms are caused to cause alarm fatigue; sometimes, some medical staff are not aware or aware of the alarm fatigue can be reduced by adjusting the alarm threshold; secondly, how to set the alarm threshold is not intuitive enough, especially for young medical staff or new hands, it is often not known which to adjust the alarm threshold.

Referring to fig. 1, a monitoring device is provided in fig. 1, and includes a data acquisition device 10, a display 20, a memory 30, and a processor 40. The monitoring devices include, but are not limited to, any one or combination of a monitor, a local central station, a remote central station, a cloud service system, a mobile terminal, the monitor may include a bedside monitor, a wearable monitor, and the like, and the central station may include at least one of a local central station, a remote central station, and the like.

The data acquisition device 10 is used to acquire patient data of a patient state. In some embodiments, the data acquisition device 10 is a sensor assembly, a signal acquisition device, or the like, which acquires patient data by acquiring raw data, for example, when the monitoring device is a monitor, parameter values of the monitoring parameters are acquired as a part of patient data by monitoring accessories such as electrocardio, blood pressure, pulse oximetry, respiration, body temperature, cardiac output, carbon dioxide, motion data, video data, respiratory mechanics parameters, hemodynamic parameters, oxygen metabolism parameters, electroencephalogram parameters, dual-frequency indexes, microcirculation parameters, and the like, wherein the monitoring accessories can be electrically connected to the monitoring device through a connection interface on the monitoring device, and can also be integrated on the monitoring device. In other embodiments, the data obtaining apparatus 10 is a communication module, such as a wireless communication module, a wired communication module, and the like, included in the monitoring device, and the communication module is in communication connection with other monitoring devices or third party devices, and receives patient data transmitted from other monitoring devices or third party devices, where the wireless communication manner includes, but is not limited to, various mobile communication technologies (2G, 3G, 4G, and 5G), a wireless network, bluetooth Bluetooth, zigBee, ultra wideband UWB, NFC, and the like. For example, when the monitoring device is a bedside monitor, a communication connection may be made with a mobile monitor, central station, etc. to obtain patient data sent by the mobile monitor, central station, etc. For another example, when the monitoring device is a central station, the monitoring device may be in signal connection or data transmission with various monitors, ultrasound devices, LIS systems of hospitals, etc. to obtain patient data collected or secondarily processed by other devices or systems.

The display 20 is used to output information, such as visual information. The display 20 may be a display having only a display function, or may be a touch display, and when the display 20 is a touch display, the display may also receive a touch operation or a gesture operation of a user, so as to receive an instruction input by the user, and when the display 20 is a display having only a display function, the monitoring device may be connected to an input device through an external input device so as to allow the user to input an operation instruction. Input devices include, but are not limited to, keyboard, mouse, remote control, and the like.

The memory 30 may be used to store data or programs, for example, data acquired by the data acquisition device 10, data computationally generated by the processor 40, or image frames generated by the processor 40, which may be 2D or 3D images, or the memory 30 may store a graphical user interface, one or more default image display settings, programming instructions for the processor 40. The memory 30 may be a tangible and non-transitory computer readable medium such as flash memory, RAM, ROM, EEPROM, or the like.

The processor 40 may be a central processing unit (Central Processing Unit, CPU), but may also be other general purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), field programmable gate arrays (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or the like. The general purpose processor may be a microprocessor or the processor 40 may be any conventional processor or the like. The processor 40 is configured to execute instructions or programs, control the data acquisition device 10, the display 20, etc., process the received data, generate required calculation or judgment results, or generate visual data or graphics, and output the visual data or graphics to the display 20 for display. In this embodiment, the processor 40 is configured to control the monitoring device to issue an alarm when the parameter value of the monitored parameter exceeds the current alarm threshold. Wherein the alarm threshold may be an upper limit and/or a lower limit. For example, heart rate generally cannot be too high nor too low, so it has an upper threshold and a lower threshold. The upper threshold value indicates that the parameter value of the monitoring parameter exceeds the upper threshold value, and is considered abnormal to trigger an alarm. The lower threshold value indicates that the parameter value of the monitored parameter is lower than the lower threshold value, and is considered abnormal, and an alarm is triggered. The alarm threshold associated with a monitored parameter may be of only one type, i.e., the alarm threshold is related only to the monitored parameter and is independent of other monitored parameters. The unit of the value of such an alarm threshold is typically the same as the unit of the value of the monitored parameter. Of course, clinical diseases are complex, and there may be a number of monitored parameters in specific intervals, reflecting patient deterioration and requiring an alarm. The alarm thresholds associated with the monitored parameters may be varied, one being the alarm threshold associated with only one monitored parameter as described above, and the other being the alarm threshold associated with a plurality of monitored parameters. The alarm threshold value associated with the plurality of monitored parameters may be, for example, a numerical value calculated by weighting the parameter values of the plurality of monitored parameters. In some embodiments, the processor 40 may control the display 20 to display alarm information for alarm prompting, and in other embodiments, the monitoring device further includes a special alarm device to output alarm prompting, where the alarm device includes, but is not limited to, a light emitting diode or a buzzer, etc.

It should be noted that fig. 1 is only an example of the monitoring device, and this is not intended to limit the structure of the monitoring device.

Based on the above monitoring device, the embodiment shown in fig. 2 provides a threshold setting guiding method, which includes the steps of:

step S100, obtaining patient data representing a patient state.

The patient data referred to in this step includes at least one of monitoring parameter data, illness state data, parameter alarm data, user interaction data, test data, and examination data, and this embodiment is described by taking all of the above as examples.

The monitored parameter data includes at least one of a monitored parameter type, a parameter value of the monitored parameter, a variation trend of the parameter value of the monitored parameter, and a parameter alarm switch state, and the embodiment is described by taking the above four examples. The monitoring parameters comprise one or more of electrocardio, respiration, noninvasive blood pressure, blood oxygen saturation, pulse, body temperature, invasive blood pressure, end-of-breath carbon dioxide, respiratory mechanics, anesthetic gas, cardiac output, brain electricity double-frequency index and the like. The trend of the change of the parameter value of the monitored parameter reflects whether the patient's illness state is worsened or is kept relatively stable, and the parameter alarm switch state can reflect the attention degree of medical staff to the monitored parameter. Therefore, in the subsequent embodiment, the data are used as one of the bases for judging whether the alarm threshold is adjusted, so that the judgment accuracy can be improved.

The condition data includes at least one of patient basic information (such as age, height, weight, sex, etc.), disease diagnosis information, treatment plan information, care record information, and natural language information on the electronic medical record system, and the embodiment is described by taking the above five examples as included. The doctor may generate disease data during examination, diagnosis, treatment, etc. of the patient, and the disease data may be introduced into the monitoring device through a hospital information management system (HIS), a clinical Laboratory Inspection System (LIS), an electronic medical record system (EMR), a Laboratory Automation System (LAS), etc. of the hospital or department, or may be manually input into the monitoring device by the doctor or nurse.

The parameter alarm data comprises at least one of monitoring parameter alarm times, monitoring parameter alarm time, alarm priority and audible and visual settings of monitoring parameter alarms. Alarm priority refers to which alarm is output preferentially when there are typically multiple alarms. The parameter alarm data may be recorded by the processor 40. Parameter alarm data may be recorded while the processor 40 controls the monitoring device to alarm prompts.

The user interaction data comprises at least one of monitoring parameter alarm conditions set by a user in the monitoring time, operation of opening or closing a monitoring parameter alarm switch by the user, the frequency and/or the frequency of processing monitoring parameter alarms by the user and response time of the user to the monitoring parameter alarms. The monitoring device can obtain user interaction data by recording the input operation of a user, wherein the alarm condition can be such conditions as which monitoring parameter values reach which interval to trigger an alarm, and the like.

The test data includes biochemical test index data including at least one of blood routine test data, liver function test data, kidney function test data, thyroid test data, urine test data, immune test data, blood coagulation test data, blood gas test data, stool routine test data, and tumor marker test data. The examination data includes at least one of DR image data, CT image data, MRI image data, PET image data, ultrasound image data, scale data, and physical examination data.

Step 200, generating the monitoring interface 100 from at least a portion of the patient data. The monitoring interface 100 is capable of displaying a plurality of first display elements, and the monitoring interface 100 displays the monitored parameters of the patient through one of the plurality of first display elements or a combination of the plurality of first display elements.

Fig. 3-5 illustrate an exemplary monitoring interface 100, wherein the first display element includes at least numerals, characters, curves, icons, and the like. From the perspective of a user, at least the type of the monitored parameter, the parameter value of the monitored parameter, the waveform curve of the monitored parameter and the alarm threshold limit mark 130 corresponding to the monitored parameter included in the monitored interface 100 can be observed, and the alarm threshold limit mark 130 can prompt the user of the current alarm threshold of the monitored parameter, wherein the type of the monitored parameter and the parameter value of the monitored parameter are represented by first display elements of characters or numbers, the waveform curve of the monitored parameter is represented by first display elements of the curve, and the alarm threshold limit mark 130 of the monitored parameter is represented by first display elements of icons. In addition, the monitoring interface 100 in some embodiments further includes a hot key icon 120, where the hot key icon 120 is linked to a preset program, and is used to invoke the linked program in response to the operation of the user, so as to execute the specific function of the monitoring device. It will be appreciated that the monitoring interface 100 of fig. 3-5 is merely exemplary, and that other monitoring interfaces 100 may include more or less patient data, such as patient test data, examination data, etc. may also be displayed on the monitoring interface 100 in some embodiments.

Step S300, judging whether the current alarm threshold associated with the monitored parameter of the patient needs to be adjusted according to the patient data. When the adjustment is required, step S400 is performed.

According to different patient data, the mode of judging whether the current alarm threshold associated with the monitoring parameter needs to be adjusted is different.

In some embodiments, it may be determined from the monitored parameter data whether the current alarm threshold associated with the monitored parameter needs to be adjusted. For example, whether the current alarm threshold needs to be adjusted is determined according to the degree to which the parameter value of the monitored parameter exceeds the current alarm threshold, wherein the degree to which the current alarm threshold is exceeded includes, but is not limited to, a value that exceeds the current alarm threshold, a number of times that the current alarm threshold is exceeded, and a duration that the current alarm threshold is exceeded. The parameter value of the monitored parameter can be obtained from the monitored parameter data in the preset first time period, the value exceeding the current alarm threshold is determined according to the extreme value in the parameter value of the monitored parameter, and if the value exceeds the preset value threshold, the current alarm threshold is judged to be required to be adjusted; or determining the times that the parameter value of the monitoring parameter exceeds the current alarm threshold value in the first time period, and judging that the current alarm threshold value needs to be adjusted if the times exceed the preset times threshold value; or recording the time length that the parameter value of the monitoring parameter exceeds the current alarm threshold value in the first time period, and judging that the current alarm threshold value needs to be adjusted if the time length exceeds the preset time length threshold value. In particular, in one application, the monitoring device may obtain a heart rate value (HRheart rate) of the patient per second over the past hour, and based on the heart rate value, derive: calculating to obtain a first difference value according to the heart rate minimum value and the heart rate low alarm limit when the heart rate minimum value is lower than the heart rate low alarm limit, and calculating to obtain a second difference value according to the heart rate maximum value and the heart rate high alarm limit when the heart rate maximum value is higher than the heart rate high alarm limit; a first number of times the patient's heart rate value is below the low heart rate warning limit for a past hour, and a second number of times the patient's heart rate value is above the high heart rate warning limit for a past hour; the heart rate value of the patient is below the first duration of the heart rate low alarm limit accumulation for the past hour and above the second duration of the heart rate high alarm limit accumulation for the past hour. After the above is obtained, the current alarm threshold for judging the heart rate needs to be adjusted when any of the following situations happen: the first difference value or the second difference value is larger than a preset numerical threshold; the first times or the second times are larger than a preset times threshold value; and the first time length or the second time length is larger than a preset time length threshold value. In other embodiments, a comprehensive value can be obtained according to a preset rule according to the value of the parameter value of the monitored parameter exceeding the current alarm threshold, the number of times of exceeding the current alarm threshold and the duration of exceeding the current alarm threshold, and the degree of exceeding the current alarm threshold by the parameter value of the monitored parameter is represented by the comprehensive value, so that whether the current alarm threshold needs to be adjusted is judged according to the comprehensive value. For example, the integrated value may be calculated using the following equation:

W0=aw1+bw2+cw3, where W0 is a comprehensive value, W1 is a value of the monitored parameter in the first period exceeding the current alarm threshold, W2 is the number of times the monitored parameter in the first period exceeds the current alarm threshold, W3 is an accumulated duration of the monitored parameter in the first period exceeding the current alarm threshold, and a, b, and c are preset weight coefficients respectively.

In some embodiments, it may be determined from the parameter alarm data whether the current alarm threshold associated with the monitored parameter needs to be adjusted. For example, whether the current alarm threshold needs to be adjusted is judged according to the monitoring parameter alarm times and/or the monitoring parameter alarm time length. At least one of the monitoring parameter alarming times and the monitoring parameter alarming time length can be obtained from a preset second time period, and when the monitoring parameter alarming times in the second time period exceed a certain number of times or the monitoring parameter alarming time length in the second time period exceeds a certain time length, the current alarming threshold value related to the monitoring parameter is judged to need to be adjusted. For example, continuing to describe with the heart rate value of the patient, if the monitoring device records that the heart rate high alarm occurs more than a certain number of times in the past hour, the current heart rate high alarm is considered to be too frequent, and the current alarm threshold value related to the heart rate is judged to need to be adjusted. In other embodiments, whether the current alarm threshold needs to be adjusted may also be determined according to the time interval at which the monitoring parameter alarm occurs, for example, when multiple "heart rate high" alarms occur continuously in a short time, it is determined that the current heart rate high alarm limit is unreasonably set and needs to be adjusted.

In some embodiments, it may also be determined from the user interaction data whether the current alarm threshold associated with the monitored parameter needs to be adjusted. For example, the number and/or frequency of the user processing the monitoring parameter alarm in the preset third time period is obtained, and whether the current alarm threshold associated with the corresponding monitoring parameter needs to be adjusted is judged according to the number and/or frequency of the user processing the monitoring parameter alarm in the third time period. In particular, the monitoring device can record the number of times that a healthcare worker cancels an alarm through a key on the monitoring device in the past one hour, if the healthcare worker has never cancelled the alarm in the past one hour, it is determined that the current alarm threshold does not need to be adjusted if the healthcare worker is very concerned about the alarm, and if the healthcare worker has largely cancelled the alarm that occurred in the past one hour, it is determined that the healthcare worker is not concerned about the alarm or that the alarms may be invalid to the healthcare worker, it is determined that the current alarm threshold needs to be adjusted.

In some embodiments, when determining whether the current alarm threshold needs to be adjusted according to the user interaction data, the correlation between the parameters of the adjusted threshold may also be combined to determine whether the current alarm threshold of the monitored parameter needs to be adjusted. For example, the heart rate and the pulse are homologous signals, and if the current alarm threshold value of the heart rate is detected to be adjusted by the user, then the current alarm threshold value of the pulse is judged to also need to be adjusted.

Different patient data can also be combined with the current alarm threshold value which jointly judges a certain monitoring parameter needs to be adjusted, for example, the current alarm threshold value of the heart rate does not need to be adjusted when the number of times of alarm with high heart rate in the past hour exceeds a certain number of times, but the user is not detected to cancel any alarm, and the current alarm number is judged to be increased because the condition of the patient is rapidly deteriorated.

Step S400, outputting a threshold setting guide for prompting a user to adjust the current alarm threshold. By outputting the threshold setting guide on the monitoring interface 100, the user can consider whether to adjust the current alarm threshold while providing the relevant information of the monitoring parameters, and the medical staff can fully combine the information on the monitoring interface 100 to judge.

In some embodiments, a second display element is additionally displayed in the monitoring interface 100 to prompt the user to adjust the current alarm threshold, where the second display element may be of a completely different type than the first display element, for example, an icon of a shape that was not present in the monitoring interface 100, or may be of the same type as the first display element, for example, the same shape as the hotkey icon 120 in the monitoring interface 100. In some embodiments, the second display element is the alarm threshold recommendation flag 110 shown in fig. 3 and 4. When the indicia is displayed in the monitor interface 100, the user can know the alarm threshold value of the monitoring parameter to be adjusted. It can be appreciated that, since the second display element is newly displayed in the monitor interface 100, the second display element can be easily attracted to the attention of the user, in other words, the manner of newly displaying the second display element in this embodiment can better prompt the user to consider to adjust the current alarm threshold.

In some embodiments, the alarm threshold suggestion flag 110 may be further highlighted. It will be appreciated that highlighting herein refers to the alarm threshold suggestion marker 110 being able to draw more attention to the user than the first display element, so that the manner in which it is able to draw attention to the user is highlighting. In some embodiments, highlighting refers to highlighting of the alarm threshold recommendation flag 110 itself, the alarm threshold recommendation flag 110 being displayed in a manner that includes, but is not limited to, flashing, i.e., the alarm threshold recommendation flag 110 is continuously flashing within the monitoring interface 100; an enlarged display, such as alarm threshold advice tab 110, is the largest of all display elements in the monitoring interface 100; highlighting, for example, alarm threshold suggestion markers 110 are filled in with yellow or red and displayed differently than the other first display element. In other embodiments, highlighting of the alarm threshold recommendation flag 110 refers to displaying it in a conspicuous location, such as displaying the alarm threshold recommendation flag 110 in a location where the user's line of sight would stay for a first time in the center or top of the monitoring interface 100, or displaying the alarm threshold recommendation flag 110 near a particular first display element, such as displaying the alarm threshold recommendation flag 110 near a parameter value, waveform profile, or alarm threshold limit flag 130 that requires adjustment of the monitored parameter of the current alarm threshold. In some embodiments, when the current alarm thresholds of multiple monitoring parameters need to be adjusted, a corresponding number of alarm threshold advice marks 110 may be correspondingly and newly displayed in the monitoring interface 100, for example, in fig. 4, when the current alarm thresholds of both the electrocardiograph parameter and the blood oxygen parameter need to be adjusted, the alarm threshold advice marks 110 are newly displayed near the alarm threshold limit marks 130 of the electrocardiograph parameter and the alarm threshold limit marks 130 of the blood oxygen parameter.

In some embodiments, the monitoring interface 100 does not add a first display element, but changes a display attribute of a target display element, so as to prompt the user to adjust the current alarm threshold, where the target display element is a preset one of the first display elements. It has been described above that the first display element in the monitoring interface 100 includes at least the hotkey icon 120 and the parameter value, the waveform profile, and the alarm threshold limit mark 130 corresponding to the current alarm threshold of each monitored parameter, and the target display element may be the hotkey icon 120 or any one of the parameter value, the waveform profile, and the alarm threshold limit mark 130 of the monitored parameter that needs to adjust the current alarm threshold. Taking fig. 5 as an example, when the current Alarm threshold of any monitoring parameter needs to be adjusted, changing the display attribute of the hotkey icon 120, which is "Alarm Reset" in the figure; alternatively, the display attribute of the parameter value, waveform profile, or alarm threshold limit marker 130 of the central electrical parameter of the map is changed when the current alarm threshold of the electrical cardiac parameter needs to be adjusted, and the display attribute of the parameter value, waveform profile, or alarm threshold limit marker 130 of the blood oxygen parameter of the map is changed when the current alarm threshold of the blood oxygen parameter needs to be adjusted. Ala rm Reset refers to an Alarm Reset key for resetting an Alarm, typically when a healthcare worker clicks the hotkey icon 120 "Alarm Reset", indicating that the healthcare worker has acknowledged the current Alarm, the Alarm system is Reset and does not continue to output the current Alarm. When the monitoring equipment is in an alarm reset state, if a new alarm is generated, the alarm reset icon disappears, and the newly generated alarm is output as usual, namely, the newly generated alarm audible and visual prompt is normal. In the embodiments of the present application, the display attribute of the hotkey icon 120, which is "Alarm Reset" in the drawing, is not limited to being changed, but may be changed.

Changing the display attribute of the target display element in this step, including any visually perceived display change, may include, for example, but not limited to, changing the display color of the target display element, changing the background color of the area in which the target display element is located in the monitoring interface 100, changing the size of the target display element, changing the blinking manner of the target display element, that is, changing the type, the content, etc. of the target display element to be within the range of changing the display attribute of the target display element, where changing the blinking manner of the target display element refers to switching one of the blinking display and the non-blinking display to the other when the current alarm threshold needs to be adjusted, for example, in some embodiments, the parameter value of the monitored parameter in the monitoring interface 100 is blinking displayed according to the set refresh rate, and when the current alarm threshold of the monitored parameter needs to be adjusted, the parameter value of the monitored parameter is changed from blinking display to non-blinking display, thereby prompting the user to adjust the current alarm threshold of the monitored parameter. In addition, for different target display elements, there may be a targeted manner of changing the display attribute, for example, when the target display element is a parameter value of the monitored parameter, the font type, the font thickness, and the like of the parameter value may be changed. In some embodiments, when the current alarm thresholds of multiple monitored parameters need to be adjusted, the relevant first display elements of the multiple monitored parameters can be used as target display elements, and the display attributes of the corresponding target display elements are changed, for example, when the current alarm thresholds of the electrocardiograph parameters and the blood oxygen parameters in fig. 5 need to be adjusted, the display attributes of the alarm threshold limit markers 130 of the electrocardiograph parameters and the display attributes of the alarm threshold limit markers 130 of the blood oxygen parameters can be changed simultaneously.

Step S500, detecting whether an adjustment threshold request of a user response threshold setting guide input is received.

In this step, the receiving entrance of the threshold adjustment request is set on the monitoring interface 100, that is, when the user sees the threshold setting guide and intends to adjust the current alarm threshold, the threshold adjustment request can be directly input on the monitoring interface 100, so that the current alarm threshold can be adjusted later, and the work of the medical staff is more efficient.

In some embodiments, when the monitoring interface 100 prompts to adjust the current alarm threshold by displaying the second display element in a new manner, the second display element may be directly used as a receiving inlet of the threshold adjustment request, and the new display of the alarm threshold suggestion mark 110 is taken as an example for explanation, after displaying the alarm threshold suggestion mark 110, if the clicking operation of the alarm threshold suggestion mark 110 by the user is detected, the adjustment threshold request input by the user is determined to be received. It is to be understood that the clicking operation herein is merely an example, and it is also possible to determine whether a threshold adjustment request input by the user is received by detecting whether a drag operation, a slide operation, or the like for the alarm threshold suggestion mark 110 is received.

In other embodiments, when the monitoring interface 100 prompts to adjust the current alarm threshold by displaying the second display element in addition, the other first display element is used as a receiving entry for the threshold adjustment request. Continuing to take fig. 3 as an example, the "Alarm Reset" hot key icon 120 may be used as a receiving entry of the threshold adjustment request, and after the Alarm threshold suggestion flag 110 is displayed, if the user's click operation on the "Alarm Reset" hot key icon 120 is detected, it is determined that the threshold adjustment request input by the user is received. It should be understood that, in some embodiments, the hotkey icon 120, which is "Alarm Reset", may not be used as a receiving entry of the threshold adjustment request, but any other hotkey icon related to Alarm setting may be used as a receiving entry of the threshold adjustment request, and if a user's click operation on the hotkey icon is detected, it is determined that the threshold adjustment request input by the user is received. In some embodiments, when a second display element is displayed in the monitoring interface 100, the second display element may be displayed in the vicinity of the first display element as a receiving portal for the threshold adjustment request to serve as a notification to the user of the location of the input threshold adjustment request, e.g., when the "Alarm Reset" hotkey icon 120 is the receiving portal for the threshold adjustment request, the Alarm threshold suggestion marker 110 is displayed in the vicinity of the "Alarm Reset" hotkey icon 120.

In some embodiments, when the current alarm threshold is to be adjusted by changing the display attribute of the target display element, the target display element may be directly used as a receiving inlet of the threshold adjustment request, for example, in fig. 5, when the current alarm threshold of the electrocardiograph parameter needs to be adjusted, the electrocardiograph parameter value on the monitoring interface 100 starts to flash, and if the clicking operation of the user on the parameter value is detected, the threshold adjustment request input by the user is determined to be received.

In other embodiments, when the adjustment of the current alarm threshold is prompted by changing the display attribute of the target display element, other first display elements may also be used as receiving entries for the threshold adjustment request. For example, in fig. 5, when the current Alarm threshold of the electrocardiograph parameter needs to be adjusted, the parameter value of the electrocardiograph parameter on the monitoring interface 100 starts to flash, and if the user's click operation on the "Alarm Reset" hotkey icon 120 is detected, it is determined that the adjustment threshold request input by the user is received.

Step S600, providing the user with a threshold setting interface 200 of the monitored parameters. The threshold setting interface 200 can receive an adjustment operation of the current alarm threshold by the user.

The threshold setting interface 200 is not limited in this embodiment, and all existing and future interfaces that can adjust the current alarm threshold fall within the threshold setting interface 200 in this embodiment.

In some embodiments, as shown in fig. 6, the threshold setting interface 200 may not only adjust the current alarm threshold that needs to be adjusted according to patient data, but also adjust the current alarm thresholds of other monitored parameters, where each monitored parameter has a corresponding upper limit value adjustment button 210a and lower limit value adjustment button 210b, and the user may adjust the current alarm threshold of the monitored parameter by clicking the buttons. In other embodiments, the new alarm threshold may also be set directly by the user, for example by entering numbers in a pop-up window.

The threshold setting interface 200 is shown in fig. 7 in some embodiments, in which it is determined from patient data that the current alarm threshold for heart rate needs to be adjusted. The threshold setting interface 200 displays a heart rate trend graph of the patient over a period of time, it being understood that the user may customize the length of the period of time of the heart rate trend graph shown in the threshold setting interface 200, which may be, for example, 1 hour, 12 hours, 24 hours, etc. in the past. The threshold setting interface 200 further shows the current alarm threshold of the heart rate parameter of the patient, including the current alarm upper limit value 120bpm and the current alarm lower limit value 60bpm, and is represented by the indication line and the value on the threshold setting interface 200, that is, by the current alarm upper limit value indication line 220a and the corresponding value 120, and the current alarm lower limit value indication line 220b and the corresponding value 60, and for more visual display, the region between the current alarm upper limit value indication line 220a and the current alarm lower limit value indication line 220b may be further displayed by coloring. In order to better understand the reason why the current alarm threshold needs to be adjusted by the monitoring device, the threshold setting interface 200 may optionally further display the reason why the current alarm threshold needs to be adjusted according to the patient data, namely, "heart rate high alarm occurred more than 5 times in the last 60 minutes, and check the rationality of the heart rate high alarm threshold".

In the threshold setting interface 200 shown in fig. 7, an upper limit value adjusting button 210a and a lower limit value adjusting button 210b are also provided, the user can adjust the current alarm upper limit value of the heart rate by clicking the upper limit value adjusting button 210a, and lower the current alarm lower limit value of the heart rate by clicking the lower limit value adjusting button 210b, in addition, the threshold setting interface 200 provides a more graphical manner of adjusting the current alarm threshold, specifically, a suggested alarm threshold indication line 230 based on a suggested alarm threshold associated with a monitored parameter is displayed in the threshold setting interface 200, wherein the suggested alarm threshold can be input by the user, and the alarm threshold can be defined as a default alarm threshold input by the user, for example, the alarm threshold of the default heart rate is 140bpm, and the suggested alarm threshold indication line 230 in the threshold setting interface 200 appears at a position indicated by 140bpm whenever the current alarm threshold of the heart rate needs to be adjusted, besides the user input, the suggested alarm threshold can also be obtained according to patient data. In some embodiments, the recommended alarm threshold is obtained by the monitoring device according to the current alarm threshold and the reason for the current alarm threshold to be adjusted, for example, the current alarm threshold is 120bpm, and the reason for the current alarm threshold to be adjusted is that the heart rate is too high, and the preset adjustment step size 20bpm is adjusted up to be the recommended alarm threshold based on the current alarm threshold, in which case the recommended alarm threshold indicator 230 in fig. 7 is actually an adjustment recommendation for the current alarm upper limit value, and in some embodiments, the recommended alarm threshold indicator 230 may also appear below the current alarm lower limit value indicator 220b to form an adjustment recommendation for the current alarm lower limit value.

The recommended alarm threshold indication line 230 can respond to the drag or other gesture operations of the user to move up and down, and the recommended alarm threshold corresponding to the recommended alarm threshold indication line 230 also changes in the moving process, when the user clicks the application key, the recommended alarm threshold corresponding to the recommended alarm threshold indication line 230 is used as a new alarm threshold when the user clicks the application key. In some embodiments, the suggested alarm threshold is displayed in real-time based on the position of the suggested alarm threshold indicator line 230 during the user dragging of the suggested alarm threshold indicator line 230, which is displayed between the upper limit adjustment buttons 210a in fig. 7. Optionally, in fig. 7, there is also a linkage relationship between the upper limit value adjustment button 210a and the suggested alarm threshold indication line 230, for example, when the user clicks the upper limit value adjustment button 210a to adjust 140bpm to 150bmp, the suggested alarm threshold indication line 230 also rises to a position corresponding to 150 bmp.

In some embodiments, when the current alarm thresholds of multiple monitoring parameters all need to be adjusted, the monitoring device also provides a switch tab field of the threshold setting interface 200 for different monitoring parameters, as shown in fig. 8, and the user can switch by clicking the switch tab field on the left side.

The monitoring device of the embodiment is guided by the setting of the alarm threshold, which is beneficial to reducing nonsensical alarm, helping a user judge whether the current alarm threshold related to the monitoring parameter needs to be adjusted or not, and reducing the waste of energy and time of the user.
