Description

A monitoring device and its alarm threshold setting guidance method

technical field

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

Background technique

The monitoring equipment is connected with the patient and used to monitor the patient's physiological parameters. During the use of the monitoring equipment, the medical staff will judge the normal value range of each parameter based on clinical research statistics and clinical experience to pre-set the parameter alarm threshold. When the patient When the measured value of the parameter exceeds the preset alarm threshold, the monitoring device will generate an alarm to remind the medical staff that the patient may have an abnormal physiological state. However, due to differences in the patient's vital signs and treatment measures, the measured values of physiological parameters between patients will vary greatly. For example, the patient's basal heart rate is relatively high, exceeding 120bpm; or the patient is treated with heart rate-lowering drugs , so that the patient's heart rate is lower than 50bpm; these will cause the measured value of the patient's physiological parameters to exceed the preset parameter alarm threshold range, thereby generating a large number of parameter alarms. However, these alarms are not of clinical concern and are meaningless alarms. Too many meaningless alarms will cause alarm fatigue, delay the medical staff's response to the alarm, disrupt the medical staff's judgment on the patient's status, and make it impossible to respond to the alarms that really need clinical intervention measures, seriously threatening the safety of patients and reducing monitoring. the quality of.

Although existing monitoring equipment generally supports medical staff to set specific alarm threshold ranges for different patients, there are still some problems. First of all, the monitor cannot automatically suggest to remind the medical staff to adjust the threshold, but to cause too many meaningless alarms and cause alarm fatigue, and the medical staff will passively change it; sometimes, some medical staff do not realize or do not know. Reduce alarm fatigue by adjusting the alarm threshold; secondly, how to set the alarm threshold is not intuitive enough, especially for young medical staff or novices, often do not know where to adjust the alarm threshold.

The data acquiring device 10 is used for acquiring patient data of a patient state. In some embodiments, the data acquisition device 10 is a sensor component, a signal acquisition device and other components, which obtain patient data by collecting raw data, for example, when the monitoring device is a monitor, through ECG, blood pressure, pulse oximetry, respiration, Monitoring accessories such as body temperature, cardiac output, carbon dioxide, exercise data, video data, respiratory mechanics parameters, hemodynamic parameters, oxygen metabolism parameters, EEG parameters, bispectral index and microcirculation parameters obtain the parameter values of monitoring parameters as A part of patient data, wherein the monitoring accessory 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 some other embodiments, the data acquisition device 10 is a communication module such as a wireless communication module and a wired communication module included in the monitoring device. The communication module communicates with other monitoring devices or third-party devices, and receives Patient data to be transmitted, among which wireless communication methods include but are not limited to various generations of mobile communication technologies (2G, 3G, 4G and 5G), wireless networks, Bluetooth, ZigBee, ultra-wideband UWB, NFC, etc. For example, when the monitoring device is a bedside monitor, it can communicate with the mobile monitor, central station, etc. to obtain patient data sent by the mobile monitor, central station, etc. For another example, when the monitoring equipment is a central station, it can perform signal connection or data transmission with various monitors, ultrasound equipment, and hospital LIS systems to obtain patient data collected or secondary processed by other equipment or systems.

The display 20 is used for outputting information, for example outputting visual information. The display 20 can be a display that only has a display function, or a touch display. When the display 20 is a touch display, it can also receive user touch operations or gesture operations to receive instructions input by the user. When the display 20 When the monitoring device is a display with only a display function, the monitoring device can be used for the user to input operation instructions through an external input device. Input devices include but are not limited to input devices such as keyboards, mice, and remote controls.

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

The processor 40 can be a central processing unit (Central Processing Unit, CPU), and can also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), on-site Field-Programmable Gate Array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general purpose processor may be a microprocessor or the processor 40 may be any conventional processor or the like.

Wherein, the alarm threshold may be an upper limit and/or a lower limit. For example, heart rate is usually neither too high nor too low, so it has an upper threshold and a lower threshold. The upper threshold indicates that if the parameter value of the monitoring parameter exceeds the upper threshold, it is considered abnormal and an alarm is triggered. The lower limit threshold indicates that if the parameter value of the monitoring parameter is lower than the lower limit threshold, it is considered abnormal and an alarm is triggered. There can be only one alarm threshold associated with the monitoring parameter, that is, the alarm threshold is only related to the monitoring parameter and has nothing to do with other monitoring parameters. The numerical units of such alarm thresholds are usually the same as those of monitoring parameters. Of course, clinical diseases are more complicated, and when the values of multiple monitoring parameters are in a specific interval, it reflects that the patient's condition is deteriorating and an alarm is required. Therefore, there may be multiple alarm thresholds associated with the monitoring parameters, one is the alarm threshold related to only one monitoring parameter as above, and the other is the alarm threshold related to multiple monitoring parameters. The alarm threshold related to multiple monitoring parameters may, for example, be a numerical value calculated by weighting the parameter values of the multiple monitoring parameters.

The parameter alarm data includes at least one of monitoring parameter alarm times, monitoring parameter alarm duration, alarm priority, and sound and light settings for monitoring parameter alarms. Alarm priority refers to which alarm is output first when there are usually multiple alarms. The above parameter alarm data can be recorded by the processor 40 . When the processor 40 controls the monitoring device to give an alarm prompt, the parameter alarm data can be recorded.

User interaction data includes the monitoring parameter alarm conditions set by the user during the monitoring time, the user’s operation of turning on or off the monitoring parameter alarm switch, the number and/or frequency of the user’s processing of the monitoring parameter alarm, and the user’s response time to the monitoring parameter alarm. A sort of. The monitoring device can obtain the user interaction data by recording the user's input operation. Among them, the alarm condition can be which monitoring parameter value reaches which range triggers the alarm and other conditions. The value of which monitoring parameters reaches which interval triggers the alarm, and can also assist in judging whether the current alarm threshold is reasonable.

Step 200, generating the monitoring interface 100 according to at least part of the patient data. The monitoring interface 100 can display a plurality of first display elements, and the monitoring interface 100 displays monitoring parameters of the patient through one first display element or a combination of several first display elements among the plurality of first display elements.

3 to 5 show a typical monitoring interface 100, wherein the first display elements include at least numbers, characters, curves and icons. From the user's point of view, at least the types of monitoring parameters included in the monitoring interface 100, the parameter values of the monitoring parameters, the waveform curves of the monitoring parameters, and the alarm threshold limit marks 130 corresponding to the monitoring parameters can be observed. It can remind the user of the current alarm threshold of the monitoring parameter, wherein the type of monitoring parameter and the parameter value of the monitoring parameter are represented by the first display element of the character or number type, and the waveform curve of the monitoring parameter is represented by the first display element of the curve type , the alarm threshold limit mark 130 of the monitoring parameter is represented by the first display element of the icon class. In addition, the monitoring interface 100 in some embodiments also includes a necessary hot key icon 120, the hot key icon 120 is linked to a preset program, which is used to call the linked program in response to the user's operation to execute the monitoring function. device-specific features. It can be understood that the monitoring interface 100 in FIGS. 3 to 5 is only an example, and other monitoring interfaces 100 may also include more or less patient data. For example, the monitoring interface 100 in some embodiments may also display the patient's data. Inspection data and inspection data, etc.

Step S300 , according to the patient data, it is judged whether the current alarm threshold associated with the monitoring parameters of the patient needs to be adjusted. When adjustment is required, step S400 is performed.

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

In some embodiments, it may be determined according to the monitoring parameter data whether the current alarm threshold associated with the monitoring parameter needs to be adjusted. For example, it is judged whether the current alarm threshold needs to be adjusted according to the degree to which the parameter value of the monitoring parameter exceeds the current alarm threshold, wherein the degree of exceeding the current alarm threshold includes but is not limited to the value exceeding the current alarm threshold, the number of times exceeding the current alarm threshold, and the number of times exceeding the current alarm threshold. The duration of the alarm threshold. The parameter value of the monitoring parameter can be obtained from the monitoring parameter data in the preset first time period, and the value exceeding the current alarm threshold is determined according to the extreme value of the parameter value of the monitoring parameter. If the value exceeds the preset value threshold, it is judged The current alarm threshold needs to be adjusted; or, determine the number of times the parameter value of the monitoring parameter exceeds the current alarm threshold in the first time period, and if the number of times exceeds the preset threshold, it is judged that the current alarm threshold needs to be adjusted; or, record in The time period during which the parameter value of the monitoring parameter exceeds the current alarm threshold in a period of time. If the time exceeds the preset time length threshold, it is determined that the current alarm threshold needs to be adjusted. Specifically in an application, the monitoring device can obtain the heart rate value (HRheart rate) per second of the patient in the past hour, and based on the heart rate value, obtain the following content: the minimum heart rate and the maximum heart rate in the past hour, when the minimum heart rate is lower than When the heart rate is low alarm limit, the first difference is calculated according to the heart rate minimum value and the heart rate low alarm limit, and when the heart rate maximum value is higher than the heart rate high alarm limit, the second difference is calculated according to the heart rate maximum value and the heart rate high alarm limit; The first number of times the patient's heart rate value was lower than the low heart rate alarm limit in the past hour, and the second time the heart rate value was higher than the high heart rate alarm limit in the past hour; the patient's heart rate value was lower than the low heart rate alarm limit in the past hour The first accumulated time limit, and the second accumulated time when the heart rate value is higher than the high heart rate alarm limit in the past hour. After obtaining the above content, when any of the following situations occurs, the current alarm threshold for judging the heart rate needs to be adjusted: the first difference or the second difference is greater than the preset value threshold; the first or second number is greater than the preset number a threshold; and the first duration or the second duration is greater than the preset duration threshold. In some other embodiments, an integrated value can also be obtained through preset rules according to the value of the monitoring parameter exceeding the current alarm threshold, the number of times exceeding the current alarm threshold, and the duration of exceeding the current alarm threshold, and use the integrated Value to represent the degree to which the parameter value of the monitoring parameter exceeds the current alarm threshold, and then judge whether the current alarm threshold needs to be adjusted according to the comprehensive value. For example, the composite value can be calculated using the following formula:

W0=a*W1+b*W2+c*W3, wherein, W0 is the comprehensive value, W1 is the value of the parameter value of the monitoring parameter in the first time period exceeding the current alarm threshold, and W2 is the value of the monitoring parameter in the first time period The number of times the value of the parameter exceeds the current alarm threshold, W3 is the cumulative time during which the parameter value of the monitoring parameter exceeds the current alarm threshold in the first time period, and a, b, and c are the preset weight coefficients respectively.

In some embodiments, it may be determined according to the parameter alarm data whether the current alarm threshold associated with the monitoring parameter needs to be adjusted. For example, it is judged whether the current alarm threshold needs to be adjusted according to the monitoring parameter alarm times and/or the monitoring parameter alarm duration. At least one of the monitoring parameter alarm times and the monitoring parameter alarm duration can be obtained from the preset second time period. When the monitoring parameter alarm times in the second time period exceed a certain number of times, or the monitoring parameter alarm duration in the second time period exceeds After a certain period of time, it is judged that the current alarm threshold associated with the monitoring parameters needs to be adjusted. For example, continue to explain with the heart rate value of the patient. If the monitoring device records more than a certain number of "high heart rate" alarms in the past hour, it is determined that the current "high heart rate" alarms are too frequent, and it is judged that the heart rate-related current alarm threshold. In other embodiments, it is also possible to judge whether the current alarm threshold needs to be adjusted according to the time interval between monitoring parameter alarms, for example, when multiple "high heart rate" alarms occur continuously in a short period of time, the current high heart rate alarm limit setting unreasonable and needs to be adjusted.

In some embodiments, it may also be determined according to the user interaction data whether the current alarm threshold associated with the monitoring parameter needs to be adjusted. For example, obtain the number and/or frequency of monitoring parameter alarms processed by the user within the preset third time period, and determine the current alarm associated with the corresponding monitoring parameter according to the number and/or frequency of monitoring parameter alarms processed by the user within the third time period Whether the threshold needs to be adjusted. Specifically, the monitoring device can record the number of times the medical staff canceled the alarm through the buttons on the monitoring device in the past hour. If the medical staff has never canceled the alarm in the past hour, it means that the medical staff is very concerned about the alarm, and judge There is no need to adjust the current alarm threshold, and if the medical staff canceled a large number of alarms that occurred in the past hour, it means that the medical staff did not pay attention to the alarms or these alarms may be invalid alarms for the medical staff. Adjust the current alarm threshold.

In some embodiments, when judging whether the current alarm threshold needs to be adjusted according to the user interaction data, it is also possible to determine whether the current alarm threshold of the monitoring parameter needs to be adjusted in combination with the correlation between the parameters whose thresholds are adjusted. For example, heart rate and pulse are homologous signals, if it is detected that the user has adjusted the current alarm threshold of heart rate, then it is judged that the current alarm threshold of pulse also needs to be adjusted.

Different patient data can also be combined to determine whether the current alarm threshold of a certain monitoring parameter needs to be adjusted. For example, although the number of alarms with high heart rate in the past hour exceeded a certain number, but it was not detected that the user canceled any of the alarms, it is judged that the current The increase in the number of alarms is due to the rapid deterioration of the patient's condition, at which point there is no need to adjust the current alarm threshold for the heart rate.

Step S400, outputting a threshold setting guide for prompting the user to adjust the current alarm threshold. By outputting threshold setting guidelines on the monitoring interface 100 , while providing relevant information on monitoring parameters, the user can be asked to consider whether to adjust the current alarm threshold, and medical personnel can make judgments based on the information on the monitoring interface 100 .

In some embodiments, a second display element is newly displayed in the monitoring interface 100 to prompt the user to adjust the current alarm threshold. An icon of a certain shape that has never appeared before may also 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 warning threshold suggestion mark 110 shown in FIGS. 3 and 4 . When the mark is newly displayed on the monitoring interface 100, the user can know that the alarm threshold of the monitoring parameter needs to be adjusted. It can be understood that since the second display element is newly displayed in the monitoring interface 100, it can easily attract the user's attention. In other words, the method of newly displaying the second display element in this embodiment can be better Prompt the user to consider adjusting the current alarm threshold.

In some embodiments, the alarm threshold suggestion mark 110 may be further highlighted. It can be understood that the highlighted display here means that compared with the first display element, the alarm threshold suggestion mark 110 can attract the user's attention more, so any display method that can attract the user's attention is highlighted show. In some embodiments, highlighting refers to the highlighting of the alarm threshold suggestion mark 110 itself, and the display mode of the alarm threshold suggestion mark 110 includes but is not limited to: flashing display, that is, the alarm threshold suggestion mark 110 is constantly flashing in the monitoring interface 100; zooming in display, e.g., the alarm threshold recommendation mark 110 is the largest of all display elements in the monitoring interface 100; highlighting, e.g., the alarm threshold recommendation mark 110 is filled with yellow or red, and otherwise performed differently from the first display element show. In some other embodiments, the highlighting of the alarm threshold suggestion mark 110 refers to displaying it in a conspicuous position, for example, displaying the alarm threshold suggestion mark 110 at the center or top of the monitoring interface 100 so that the user's line of sight will be immediately visible. Alternatively, the alarm threshold suggestion mark 110 is displayed near the specific first display element, for example, the alarm threshold suggestion mark 110 is displayed on the parameter value, waveform curve or alarm threshold limit of the monitoring parameter that needs to adjust the current alarm threshold Near marker 130. In some embodiments, when the current alarm thresholds of multiple monitoring parameters need to be adjusted, the corresponding number of alarm threshold suggestion marks 110 can be newly displayed on the monitoring interface 100, for example, in FIG. 4 , ECG parameters and the current alarm threshold of the blood oxygen parameter need to be adjusted, then the alarm threshold limit mark 130 of the ECG parameter and the alarm threshold limit mark 130 of the blood oxygen parameter are newly displayed with an alarm threshold suggestion mark 110 .

In some embodiments, the monitoring interface 100 does not add a new first display element, but changes the display attribute of the target display element, thereby prompting the user to adjust the current alarm threshold, wherein the target display element is a preset among multiple first display elements. set one. It has been explained above that the first display element in the monitoring interface 100 at least includes a hot key icon 120, and the parameter value of each monitoring parameter, the waveform curve and the alarm threshold limit mark 130 corresponding to the current alarm threshold, and the target display element It can be a hot key icon 120 , and can also be any one of the parameter value, waveform curve and alarm threshold limit mark 130 of the monitoring 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, change the display attribute of the hotkey icon 120 "Alarm Reset" in the figure; or, when the current alarm threshold of the ECG parameter needs to be adjusted, change The display attribute of the parameter value, waveform curve or alarm threshold limit mark 130 of the electrocardiographic parameter in the figure, and when the current alarm threshold value of the blood oxygen parameter needs to be adjusted, change the parameter value, waveform curve or alarm threshold limit of the blood oxygen parameter in the figure The display property of the marker 130. Alar rm Reset refers to the alarm reset key, which is used to reset the alarm. Usually, when the medical staff clicks the hot key icon 120 of "Alarm Reset", it indicates that the medical staff has confirmed the current alarm, and the alarm system is reset. Then continue to output the current alarm. When the monitoring device is in the alarm reset state, if there is a new alarm, the alarm reset icon disappears, and the new alarm is output as usual, that is, the sound and light prompt of the new alarm is normal. In each embodiment of the present application, it is not limited to changing the display attribute of the hotkey icon 120 "Alarm Reset" in the figure, but also changing the display attribute of any other hotkey icon related to the alarm setting.

In this step, changing the display attribute of the target display element includes any visually perceivable display changes, for example, may include but not limited to changing the display color of the target display element, changing the area where the target display element is located in the monitoring interface 100 Background color, changing the size of the target display element, changing the blinking mode of the target display element, etc., that is to say, changing the type and content of the target display element are all within the scope of changing the display properties of the target display element. Among them, changing the target The blinking mode of the display element refers to switching the target display element from one of blinking display and non-blinking display to another when the current alarm threshold needs to be adjusted. For example, in some embodiments, the monitor interface 100 The parameter value of the parameter is flashingly displayed according to the set refresh rate. When the current alarm threshold of the monitoring parameter needs to be adjusted, the parameter value of the monitoring parameter is changed from flashing display to non-flashing display, so as to remind the user to adjust the monitoring parameter. Current alarm threshold. In addition, for different target display elements, the way of displaying attributes can also be changed in a targeted manner. For example, when the target display element is a parameter value of a monitoring parameter, the font type and font thickness of the parameter value can be changed. In some embodiments, when the current alarm thresholds of multiple monitoring parameters need to be adjusted, the first display elements related to the multiple monitoring parameters can be used as target display elements, and the display attributes of the corresponding target display elements can be changed, For example, when the current alarm thresholds of the ECG parameter and the blood oxygen parameter in FIG. 5 need to be adjusted, the display attributes of the alarm threshold limit mark 130 of the ECG parameter and the display properties of the alarm threshold limit mark 130 of the blood oxygen parameter can be changed at the same time. .

Step S500 , detecting whether a threshold adjustment request input by the user in response to the threshold setting guide is received.

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

In some embodiments, when the monitoring interface 100 prompts to adjust the current alarm threshold by newly displaying a second display element, the second display element can be directly used as the receiving entry of the threshold adjustment request to newly display the alarm threshold suggestion mark 110 For example, after the alarm threshold suggestion mark 110 is displayed, if a user's click operation on the alarm threshold suggestion mark 110 is detected, it is determined that a threshold adjustment request input by the user has been received. It can be understood that the click operation here is only an example, and it may also be determined whether a threshold adjustment request input by the user is received by detecting whether a drag operation or a slide operation on the alarm threshold suggestion mark 110 is received.

In some other embodiments, when the monitoring interface 100 prompts to adjust the current alarm threshold by newly displaying the second display element, another first display element is used as an entry for receiving the threshold adjustment request. Continuing to take Figure 3 as an example, the "Alarm Reset" hotkey icon 120 can be used as the threshold adjustment request receiving entry. After the alarm threshold suggestion mark 110 is displayed, if the user clicks on the "Alarm Reset" hotkey icon After the operation, it is judged that the threshold adjustment request input by the user has been received. It should be understood that, in some embodiments, the hotkey icon 120 of "Alarm Reset" may not be limited to the threshold value adjustment request receiving entry, but any other hotkey icon related to the alarm setting may be used as the threshold value The entry for receiving the adjustment request, if it detects the user's click operation on the hotkey icon, then it is determined that the threshold adjustment request input by the user has been received. In some embodiments, when the monitoring interface 100 displays the second display element, the second display element may be displayed near the first display element as the threshold adjustment request receiving entry, so as to inform the user to input the threshold adjustment. The role of the location of the request, for example, when the “Alarm Reset” hotkey icon 120 is the threshold adjustment request receiving entry, the alarm threshold suggestion mark 110 is displayed near the “Alarm Reset” hotkey icon 120 .

In some embodiments, when the display attribute of the target display element is changed to prompt to adjust the current alarm threshold, the target display element can be directly used as the threshold adjustment request receiving entry. For example, in FIG. 5, when the current alarm of the ECG parameter When the threshold needs to be adjusted, the parameter value of the ECG parameter on the monitoring interface 100 starts to flicker and display, and if the user's click operation on the parameter value is detected, it is determined that the threshold adjustment request input by the user has been received.

In some other embodiments, when prompting to adjust the current alarm threshold by changing the display attribute of the target display element, other first display elements may also be used as an entry for receiving the threshold adjustment request. For example, in FIG. 5 , when the current alarm threshold of the ECG parameter needs to be adjusted, the parameter value of the ECG parameter on the monitoring interface 100 starts to flash and display, and if it is detected that the user clicks on the “Alarm Reset” hotkey icon 120, then It is determined that a threshold adjustment request input by a user has been received.

Step S600, providing the user with the monitoring parameter threshold setting interface 200. The threshold setting interface 200 can receive the user's adjustment operation on the current alarm threshold.

In some embodiments, the threshold setting interface 200 is shown in FIG. 7 . In this embodiment, it is determined that the current alarm threshold of the heart rate needs to be adjusted according to the patient data. The threshold setting interface 200 shows the heart rate trend graph of the patient in the past period of time. It should be understood that the user can customize the time period length of the heart rate trend graph shown in the threshold setting interface 200, for example, it can be the past 1 hours, 12 hours or 24 hours etc. The current alarm threshold of the patient's heart rate parameter is further shown in the threshold setting interface 200, including the current alarm upper limit value 120bpm and the current alarm lower limit value 60bpm, which are represented by indicator lines and numerical values on the threshold setting interface 200, that is, It is represented by the current alarm upper limit indicator line 220a and the corresponding value 120, and the current alarm lower limit indicator line 220b and the corresponding value 60. In order to display more vividly, the current alarm upper limit indicator line 220a and The area between the current alarm lower limit indicating lines 220b is displayed in color. In order to allow users to better understand the reason why the monitoring device needs to adjust the current alarm threshold, optionally, the threshold setting interface 200 can also display the reason that the current alarm threshold needs to be adjusted according to the patient data, that is, "more than 5 high heart rate alarms, check the rationality of the high heart rate alarm threshold".

Specifically, in the threshold setting interface 200, there is also A suggested alarm threshold indicator line 230 based on a suggested alarm threshold associated with the monitoring parameters is displayed, wherein the suggested alarm threshold can be input by the user, and can also be defined as a default alarm threshold, for example, the default heart rate alarm threshold is 140bpm, then whenever the current alarm threshold of the heart rate needs to be adjusted, the suggested alarm threshold indicator line 230 in the threshold setting interface 200 that appears is located at the position indicated by 140bpm. In addition to user input, the suggested alarm threshold can also be obtained based on patient data. In some embodiments, the suggested alarm threshold is obtained by the monitoring device according to the current alarm threshold and the reason for adjusting the current alarm threshold. If there are too many, the preset adjustment step size of 20 bpm is raised on the basis of the current alarm threshold as the suggested alarm threshold. In this case, the suggested alarm threshold indicator line 230 in FIG. In some embodiments, the suggested alarm threshold indicator line 230 may also appear below the current lower alarm limit indicator line 220b, forming an adjustment suggestion for the current lower alarm limit.
