This disclosure relates to the technical field of medical equipment, and particularly to a statistical display method for physiological parameter of a monitoring apparatus, a monitoring apparatus and computer readable medium.
With the development of the times and the advancement of technology, the medical level has also been greatly improved. Since a monitoring apparatus can provide important patient information for medical clinical diagnosis, it has been widely used. The monitoring apparatus is a practical precision medical equipment in the hospital, which can monitor the physiological parameter(s) of a patient in real time and provide a basis for emergency response and treatment to the doctor. The physiological parameters measured and monitored by the monitoring apparatus may include ECG (Electrocardiograph) signal, EMG (Electromyography) signal, blood oxygen signal, EEG (ElectroEncephalo Graph) signals, etc. The monitoring apparatus can receive the patient's ECG signals, perform QRS wave detection and classification on the ECG signals, distinguish normal heartbeat and ventricular premature beat, and calculate and display in an interface of the monitoring apparatus physiological parameters such as heart rate, the number of ventricular premature beat per minute, arrhythmia alarm, etc. Also, the monitoring apparatus can record the historical waveform of the ECG signal, the trend chart of the heart rate and the number of ventricular premature beat per minute, and the event list of the arrhythmia alarm.
Ventricular premature beat is common in those patients with heart disease. It can be secondary to any type of heart disease, and its influences on the human body are also very different in different situations. The ventricular premature beat which is mild can have no influence, while which is severe can cause fatal arrhythmias such as ventricular tachycardia and ventricular fibrillation. The severity of the ventricular premature beat can be classified by the frequency and morphological changes of the ventricular premature beat. If medical staff want to know the recent ventricular premature beat information of the patient, they can do this by: viewing the patient's ECG historical waveform and distinguishing the frequency or the morphology of the ventricular premature beat, which costs a lot of precious time of the medical staff; viewing the trend chart of the number of ventricular premature beat per minute, which trend chart can only reflect the corresponding number of ventricular premature beat per minute at each time; viewing the event list of the arrhythmia alarm related to the ventricular premature beat, in which case the event of the ventricular premature beat may not be recorded when the switch of the corresponding alarm type is turned off. In addition, if the medical staff wants to know the patient's other physiological information in the recent period, they also need to do so through such similar approach.
The disadvantage of the above technical solution is that the operation is complicated and it takes a lot of time for the medical staff.

In a second aspect, an embodiment of this disclosure may provide a monitoring apparatus. The monitoring apparatus may include a unit, such as a processor, for performing the method of the first aspect.

An embodiment of this disclosure may provide a statistical display method for physiological parameter(s) of a monitoring apparatus. The method may include steps of physiological signal acquisition, physiological signal analysis, statistical information setting and statistical display of physiological parameter.
The monitoring apparatus may use a physiological signal input module or a physiological signal acquisition device to acquire the physiological signal of a patient. The physiological signal input module may acquire the physiological signal or obtain the physiological signal from other devices. The physiological signal may include electrocardiographic signal (ECG signal), myoelectric signal (EMG signal), blood oxygen signal, and so on. For example, the monitoring apparatus may use its equipped physiological signal input module or a matched physiological signal acquisition device to collect the physiological signals of the patient. For another example, the monitoring apparatus may obtain the physiological signals from other physiological signal acquisition devices. As shown in
The physiological signal analysis module in the above-described monitoring apparatus can analyze the acquired physiological signal to obtain a result of historical physiological parameter. The processing flow of the physiological signal analysis module is shown in
The statistical information setting module in the above-described monitoring apparatus can receive statistical setting information input by the user and perform the corresponding setting operations. The processing flow of the statistical information setting module is shown in
The physiological parameter statistics display module in the above-described monitoring apparatus may perform the statistical analysis on the physiological parameter result according to the statistical setting information, and can display the statistical analysis result. The processing flow of the physiological parameter statistics display module is shown in
In the embodiment of this disclosure, the monitoring apparatus can perform the statistical analysis to obtain and further display the statistical result required by the user according to the statistical setting information input by the user, which is simple in the operation and time-saving.
Please referring to
In step 501, statistical setting information can be received and/or extracted. The statistical setting information can include a time range, a time interval, a classification rule, and a target parameter. The classification rule may define various types of the above-mentioned target parameter.
The receiving and/or extracting the statistical setting information may refer to receiving the statistical setting information input by a user, and correspondingly the statistical setting information is all input by the user. Or, the receiving and/or extracting the statistical setting information may refer to extracting the statistical setting information preset by the monitoring apparatus, and correspondingly the statistical setting information is all preset within the monitoring apparatus. Or, the receiving and/or extracting the statistical setting information may refer to both receiving a part of the statistical setting information input by the user and extracting another part of the statistical setting information from the monitoring apparatus to obtain the above-described statistical setting information. For example, the user may set the time range, the time interval, the classification rules and the target parameters. For another example, the monitoring apparatus may extract a preset time range, a preset time interval, a preset classification rule and a preset target parameter without the need of user setting. For another example, the user may set the time range and the target parameters, and the monitoring apparatus may extract the preset time interval and the preset classification rule. It can be understood that the above-described statistical setting information may all be set by the user; all may be extracted from the monitoring apparatus; or a part thereof may be set by the user, and another part thereof may be extracted from the monitoring apparatus. The above-described statistical setting information may also include other information, which is not limited in this embodiment of this disclosure.
The statistical setting information preset in the monitoring apparatus can be changed or set by the user. For example, the preset time interval of the monitoring apparatus can be 1 hour, and the user can set the time interval to be 30 minutes. For another example, the preset target parameter of the monitoring apparatus can be heart rate or pulse rate, the classification rule can be based on the range of the heart rate or the pulse rate, and the user can set the preset target parameter to be QRS wave interval, and adjust the classification rule to be based on the range of the heart rate corresponding to the QRS wave interval; where the target parameter according to the adjusted classification rule can be divided into five types: extreme bradycardia (HR<35 bpm), bradycardia (35 bpm<=HR<50 bpm), normal (50 bpm<=HR<=120 bpm), tachycardia (120 bpm<HR<=160 bpm), and extreme tachycardia (HR>160 bpm). It can be understood that the user can set the preset statistical setting information of the monitoring setting by himself. In some situations, the user can first set a part of the preset statistical setting information, and enter another part of the statistical setting information when it is needed to obtain and display the statistical result of the target parameter. In some situations, the user can first set all the preset statistical setting information, and the user does not need to do further setting when it is needed to obtain and display the statistical result of the target parameter.
The monitoring apparatus can receive the above-described statistical setting information through an input device; or the monitoring apparatus can also receive the statistical setting information sent by other devices through a receiver. For example, the user may input the statistical setting information through the input device of the monitoring apparatus, such as a keyboard, a setting button and a touch screen. For another example, the user may send the statistical setting information to the monitoring apparatus through a terminal such as a mobile phone. The above-described target parameter may be ventricular premature beat, QRS wave interval, heart rate, arrhythmia alarm event, etc., which is not limited in the embodiments of this disclosure. The above-described classification rule may define the classification method of the above target parameter. For example, when the target parameter is the heart rate or the pulse rate, the classification rule can be based on the range of the heart rate or the pulse rate, where target parameter can be divided into five types: extreme bradycardia (HR<35 bpm), bradycardia (35 bpm<=HR<50 bpm), normal (50 bpm<=HR<=120 bpm), tachycardia (120 bpm<HR<=160 bpm), and extreme tachycardia (HR>160 bpm), a total of five types. For another example, when the target parameter is the arrhythmia alarm event, the classification rule can be based on the alarm level, and thus the target parameter can be divided into four types: high-level alarm (cardiac arrest, ventricular fibrillation, ventricular tachycardia, ventricular bradycardia, extreme tachycardia, extreme bradycardia), medium-level alarm (R on T, polymorphic ventricular premature beat, ventricular premature beat bigeminy, ventricular premature beat trigeminy, bradycardia, tachycardia, unsustainable ventricular tachycardia, ventricular rhythm), low-level alarm (consecutive ventricular premature beat, heartbeat pause) and prompting alarm (two consecutive ventricular premature beat, singular ventricular premature beat, pacemaker not captured, pacemaker not paced, dropped beat, irregular rhythm, atrial fibrillation).
In step 502, N group of target parameter result corresponding to N time interval can be obtained from the result of historical physiological parameter. The N time interval can be included in the time range, and the N group of target parameter result may be the physiological parameter result corresponding to the target parameter in the result of historical physiological parameter.
The above-described monitoring equipment can acquire the physiological signal, perform corresponding analysis and processing, and obtain the physiological parameter result. For example, the monitoring apparatus can receive the patient's ECG signal, perform QRS wave detection and classification on the ECG signal, distinguish between normal heartbeat and ventricular premature beat, and calculate the physiological parameter result such as the heart rate and the arrhythmia alarm. The above-described result of historical physiological parameter may refer to the physiological parameter result before the current time instant. The above-described result of historical physiological parameter may include the results of multiple physiological parameters, or may only include the results of the target physiological parameter. For example, the result of historical physiological parameter may include the results of multiple physiological parameters (such as heart rate, QRS wave interval, and arrhythmia alarm) within a period of time before the current time instant; or the result of historical physiological parameter may only include the results of the target parameter within a period of time before the current time instant.
The N group of target parameter result corresponding to the N time interval obtained from the result of historical physiological parameter may refer to the target parameter result during N time period corresponding to the N time interval from the result of historical physiological parameter. For example, the time range is 6 hours, and the time interval is 1 hour. The entire time range includes 6 time intervals, and these 6 time intervals correspond to 6 time periods. The monitoring apparatus can thus obtain the target parameter result within these 6 time periods. The above-described result of historical physiological parameter may include the results of various physiological parameters such as the heart rate, the arrhythmia alarm event, the QRS wave interval, and the blood oxygen saturation. The N group of target parameter result is the physiological parameter result corresponding to the target parameter in the result of historical physiological parameter, for example, the physiological parameter result corresponding to the QRS wave interval.
In step 503, the number of each type of the target parameter in the N group of target parameter result may be counted according to the classification rule, and accordingly N group of statistical results corresponding to the N time interval can be obtained for each type of the target parameter.
The above-described monitoring apparatus may be preset with the classification rules of the target parameter; or the user may set the classification rule of the target parameter. For example, when the target parameter is ventricular premature beat, the classification rule can be based on the number of consecutive ventricular premature beat, which can be divided into four types: singular ventricular premature beat, two consecutive ventricular premature beat, short consecutive ventricular premature beat, and long consecutive ventricular premature beat. The monitoring apparatus can count the number of these four types of ventricular premature beats.
In step 504, the above N group of statistical result can be displayed.
The above-described monitoring apparatus may graphically display the N group of statistical result. As shown in
In the embodiment of this disclosure, the monitoring apparatus can receive the statistical setting information, perform the statistical analysis for the target parameter according to the statistical setting information, and display the statistical result. Also, the monitoring apparatus can intuitively display the statistical result of the target parameter according to the user's setting information, thus achieving simple operation.
In an optional implementation, after obtaining the N group of statistical result corresponding to the N time interval for each type of the target parameter according to the number of each type of the target parameter in the N group of target parameter result based on the classification rule, the method may further include performing an alarm operation of a target level when it is determined that the statistical result of a target group meets the alarm condition of the target level, where the statistical result of the target group is included in the N group of statistical result.
The above-described monitoring apparatus can perform one or more levels of alarm operation. Different levels of alarm operations are performed when different levels of alarm conditions are met. For example, the monitoring apparatus may include multiple alarm lights, and different levels of alarm operations may light up different alarm lights. For another example, the monitoring apparatus may include one alarm light, which sends out alarms through its different working states. For example, continuous lighting may refer to the first level of alarm, the flash at a first frequency may refer to the second level of alarm, and the flash at a second frequency may refer to the third level of alarm. For another example, the monitoring apparatus may include one alarm light, which sends out alarms through its different working states. For example, the alarm light may emit green light to indicate the first level of alarm, yellow light to indicate the second level of alarm, and red light to indicate the third level of alarm. The alarm operation is not limited in the embodiment of this disclosure.
In an optional implementation, the statistical result of the target group may include the statistical result from the statistical result of a first type of the target parameter to the statistical result of an Mth type of the target parameter.
Determining whether the statistical result of the target group meets the alarm condition of the target level may first include comparing the statistical result of an Fth type of the target parameter with an alarm threshold corresponding to the Fth type of the target parameter, where F is less than or equal to M, M is greater than or equal to 1, and the statistical result of the Fth type of the target parameter can be the number or the proportion of the Fth type of the target parameters. Determining whether the statistical result of the target group meets the alarm condition of the target level may further include determining whether the statistical result of the Fth type of the target parameter is greater than or equal to a target threshold, where the target threshold is the alarm threshold corresponding to the target level.
For example, the target parameter can be ventricular premature beat, and the classification rule can be based on the number of consecutive ventricular premature beat. Correspondingly, the target parameter of ventricular premature beat can be divided into four types: singular ventricular premature beat, two consecutive ventricular premature beats, short consecutive ventricular premature beats, and long consecutive ventricular premature beats. The monitoring apparatus may count the number of these four types of the ventricular premature beats. As shown in
Comparing the statistical result of the Fth type of the target parameter with the alarm threshold corresponding to the Fth type of the target parameter may refer to comparing whether the statistical result of the Fth type of the target parameter is greater than or equal to at least one alarm threshold corresponding to the Fth type of the target parameter. Taking the statistical results during the time period of 4 o'clock-5 o'clock as an example, the number of the long consecutive ventricular premature beats is 7, and the low-level alarm is given since the number of the long consecutive ventricular premature beats meets the low-level alarm condition of the long consecutive ventricular premature beats. The monitoring apparatus may detect whether the statistical result of each type of the target parameter meets the alarm condition of the corresponding type. When the statistical result of a certain time period meets two or more alarm conditions, the highest level of alarm operation can be performed. For example, the number of the singular ventricular premature beat in a certain time period is 60, which meets the low-level alarm threshold, the number of the short consecutive ventricular premature beats in the same time period is 21, which meets the medium-level alarm threshold, and thus a medium-level alarm operation will be performed. The above-described ventricular premature may all refer to ventricular premature beat.
In the embodiment of this disclosure, the alarm operation required to be performed can be determined accurately and quickly, and the determination process is simple.
In an optional implementation, the statistical setting information may also include an alarm threshold setting information. The alarm threshold setting information can be used for setting the alarm threshold corresponding to each type of the target parameter.
In the embodiment of this disclosure, the user may set the alarm threshold corresponding to each type of the target parameter through the alarm threshold setting information. For example, the user can set the alarm thresholds in Table 1.
In the embodiment of this disclosure, the monitoring apparatus can set the alarm threshold according to the alarm threshold setting information in the statistical setting information, which can meet the needs of different users and achieve simple operation.
In an optional implementation, before receiving the statistical setting information, the method may further include: acquiring physiological signal and preprocessing the physiological signal; calculate a time-domain characteristic and a frequency-domain characteristic of the pre-processed physiological signal; calculating, based on the time-domain characteristic and the frequency-domain characteristic, to obtain the result of historical physiological parameter.
The above-described monitoring apparatus may acquire the physiological signal of the patient through a physiological signal acquisition device or a physiological signal input module. For example, the monitoring apparatus may acquire ECG signal, blood oxygen signal etc. of the patient. Preprocessing the physiological signal may include filtering out high-frequency noise from the physiological signal, removing baseline drift of the physiological signal, and some other operations, which is not limited in the embodiment of this disclosure. The time-domain characteristic can include QRS wave position, QRS wave interval, QRS wave width and pulse wave position calculated according to the physiological signal. The frequency-domain characteristic can include spectral power distribution and effective signal frequency peak position of the physiological signal. The result of historical physiological parameter may include those physiological parameter results such as heart rate, the number of the ventricular premature beat per minute, and the arrhythmia alarm.
In the embodiment of this disclosure, the monitoring apparatus can perform the preprocessing operation and the characteristic calculation operation on the acquired physiological signal to obtain the result of historical physiological parameter for further storage, which is simple in the implementation.
In an optional implementation, obtaining the N group of target parameter result corresponding to the N time interval from the result of historical physiological parameter can include obtaining the target parameter result within the time range from the result of historical physiological parameter, segmenting the target parameter result within the time range according to the time interval to obtain the N group of target parameter result corresponding to the N time interval.
In an optional embodiment, displaying the N group of statistical result may include graphically displaying the N group of statistical result.
For example, when the time range is 6 hours and the time interval is 1 hour, the monitoring apparatus can obtain the physiological parameter result of this time range, and segment the physiological parameter result of this time range into 6 segments, where each segment is the physiological parameter result corresponding to one time interval.
The graphical display for representing the N group of statistical result can include a bar chart, a line chart, a pie chart, a doughnut chart and an area chart, which is not limited in the embodiments of this disclosure.
In the embodiment of this disclosure, the monitoring apparatus can calculate the statistical result of the target parameter according to the statistical setting information, so as to obtain the statistical result in respective time intervals when the statistical setting information is executed, which is simple in the implementation.
In a first embodiment of this disclosure, the physiological signal monitoring of a certain patient is started at 0:00, where the physiological signal monitoring includes ECG monitoring and blood oxygen monitoring. This patient is an arrhythmia patient, and there are various types of ventricular premature beats in the ECG signal. The physiological signal analysis module of the monitoring apparatus may keep analyzing the ECG signal and calculate the following ECG parameters: QRS wave classification result (normal heart beat and ventricular premature beat), QRS classification template type, QRS wave interval, heart rate and arrhythmia alarm. For this patient, there is also increase and decrease in his blood oxygen levels, and the physiological signal analysis module may also keep analyzing the blood oxygen signal to calculate the following blood oxygen parameters: pulse rate and blood oxygen saturation.
The current time instant is 6:00 and the user wants to know the statistics of the physiological parameters every hour in the incoming 6 hours. That is, the statistical information is set as follows: the time range for statistical analysis is 0:00 to 6:00, and the time interval for statistical analysis is 1 hour.
If the physiological parameter selected by the user is the ventricular premature beat, the classification rule can be based on the number of the consecutive ventricular premature beat, and the selected physiological parameter can be divided into four types: singular ventricular premature beat (1 V), two consecutive ventricular premature beats (2 V), short consecutive ventricular premature beats (3 To 5 V), and long consecutive ventricular premature beats (greater than 5 V).
If the physiological parameter selected by the user is the heart rate or the pulse rate, the classification rule can be based on the range of the heart rate or the pulse rate, and the selected physiological parameter can be divided into five types: extreme bradycardia (HR<35 bpm), bradycardia (35 bpm<=HR<50 bpm), normal (50 bpm<=HR<=120 bpm), tachycardia (120 bpm<HR<=160 bpm) and extreme tachycardia (HR>160 bpm).
If the physiological parameter selected by the user is the arrhythmia alarm event, the classification rule can be based on the alarm level, and thus the selected physiological parameter can be divided into four types: high-level alarm (cardiac arrest, ventricular fibrillation, ventricular tachycardia, ventricular bradycardia, extreme tachycardia, extreme bradycardia), medium-level alarm (R on T, polymorphic ventricular premature beat, ventricular premature beat bigeminy, ventricular premature beat trigeminy, bradycardia, tachycardia, unsustainable ventricular tachycardia, ventricular rhythm), low-level alarm (consecutive ventricular premature beat, heartbeat pause), and prompting alarm (two consecutive ventricular premature beat, singular ventricular premature beat, pacemaker not captured, pacemaker not paced, dropped beat, irregular rhythm, atrial fibrillation).
If the physiological parameter selected by the user is the QRS wave interval (the corresponding unit is ms), the classification rule can be based on the range of the heart rate corresponding to the QRS wave interval (conversion formula: 60*1000/QRS wave interval), and thus the selected physiological parameter can be divided into five types: extreme bradycardia (HR<35 bpm), bradycardia (35 bpm<=HR<50 bpm), normal (50 bpm<=HR<=120 bpm), tachycardia (120 bpm<HR<=160 bpm), and extreme tachycardia (HR>160 bpm),
If the physiological parameter selected by the user is the blood oxygen saturation, the classification rule can be based on the range of the blood oxygen saturation, and the selected physiological parameter can be divided into three types: normal blood oxygen (SpO2>=90%), medium blood oxygen (80%<=SpO2<90%), and low blood oxygen (SpO2<80%).
If the physiological parameter selected by the user is the classification template type of the ventricular premature beat, the classification rule can be based on a serial number of the template type, and thus the selected physiological parameter can be divided into N template type (from template 1 to template N). In an embodiment, there can be four types of ventricular premature beat templates for the monitored patient during the time period, namely template 1 to template 4 and 4 template types in total. The graphical display output by the physiological parameter statistics display module is shown in
If the user selects other physiological parameter, the classification can be performed according to the value range or the type of the classification rule set by the user. The physiological parameter statistics display module can output the graphical statistical result.
In the embodiment of this disclosure, the monitoring apparatus can intuitively display the statistical result of the target parameter according to the setting information of the user, and thus the operation is simple.
In a second embodiment of this disclosure, the structural schematic diagram of the monitoring apparatus in the second embodiment can be seen in
In step 1201, the statistical result of the physiological parameter can be obtained.
In step 1202, it can be determined whether the statistical result of the physiological parameter exceeds the alarm threshold. When the statistical result of the physiological parameter exceeds the alarm threshold, the step 1203 may be performed; when the statistical result of the physiological parameter fails to exceed the alarm threshold, the step 1204 may be performed.
In step 1203, the alarm operation may be performed.
In step 1204, the alarm operation may not be performed.
The object of the alarm can be the statistical information of the physiological parameter of the patient from 0 o'clock to 6 o'clock in the first embodiment. Taking the ventricular premature beat as an example of the physiological parameter to be alarmed, the alarm threshold set by the user is shown in Table 1. It can be seen that in the time period of 4 o'clock to 5 o'clock, the number of the long consecutive ventricular premature beat is 7, which meets the low-level alarm condition of the long consecutive ventricular premature beat. Thus, a low-level alarm can be provided.
In the embodiment of this disclosure, the monitoring apparatus can determine the satisfied alarm condition according to the physiological parameter statistical information and the preset alarm threshold, and perform the corresponding alarm operation to notify the user in time.
The statistical information setting module 1303 may be configured to receive and/or extract statistical setting information, which may include a time range, a time interval, a classification rule and a target parameter.
The physiological parameter statistics display module 1304 may be configured to obtain N group of target parameter result corresponding to the N time interval from a result of historical physiological parameter, where the N time interval is included in the time range, and the N group of target parameter result may refer to a physiological parameter result corresponding to the target parameter in the result of historical physiological parameter result. The physiological parameter statistics display module 1304 may also be configured to count a number of each type of the target parameter in the N group of target parameter results according to the classification rule, so as to obtain N group of statistical results corresponding to the N time interval for each type of the target parameter. Also, the physiological parameter statistics display module 1304 may be configured to display the N group of statistical result.
The specific implementing method is the same as that in
In an alternative implementation, as shown in
In an alternative implementation, the statistical result of the target group may include a statistical result from a statistical result of a first type of the target parameter to a statistical result of an Mth type of the target parameter.
The alarming module 1305 may be configured to compare a statistical result of an Fth type of the target parameter with an alarm threshold corresponding to the Fth type of the target parameter, where F is less than or equal to M, M is greater than or equal to 1, and the statistical results of the Fth type of the target parameter are the number or the proportion of the Fth type of the target parameter. The alarm module 1305 may further be configured to determine that the statistical result of the Fth type of the target parameter is greater than or equal to a target threshold, where the target threshold is an alarm threshold corresponding to the target level.
In the embodiments of this disclosure, the alarm operations needed to be executed can be accurately and rapidly determined, and the realization is simple.

The physiological parameter statistics display module 1304 may be configured to count the number of each type of the target parameter in the N group of physiological parameter result according to the classification rule, so as to obtain N group of statistical result corresponding to the N time interval for each type of the target parameter.
In the embodiments of this disclosure, the users are allowed to set the classification rules according to their own needs, instead of adopting fixed classification rule. Therefore, the needs of different users can be met.
In an alternative implementation, the statistical setting information may further include alarm threshold setting information used to set the alarm threshold corresponding to each type of the target parameter.
In the embodiment of this disclosure, the monitoring apparatus can set the alarm threshold according to the alarm threshold setting information in the statistical setting information. Therefore, the needs of different users can be met, and the operation is simple.

The implementation is simple.
