Optionally, the above target respiratory event recognition model may be a snoring event recognition model. The identification result of the target respiratory event may represent whether a snoring event occurs in the target ventilator. For example, the target respiratory event recognition model may be a decision tree model that takes the filtered gas pressure set as input data and takes the target respiratory event recognition result representing whether a snoring event occurs as output data. The above target respiratory event recognition model may include a first input layer, a first recognition model, a second input layer, a second recognition model, a third recognition model, a fourth recognition model and a decision layer.

It may be "the number of identical classification results is 2". As an example, the classification results of the above-mentioned second recognition model and the above-mentioned third recognition model may both be snoring events, and the classification results of the above-mentioned fourth recognition model may be hypoventilation events. Then the decision-making layer can determine the snoring event as the recognition result of the target respiratory event.

Step 4: In response to determining that the gas flow variance included in the operating parameter information is smaller than the reference gas flow variance, or the recognition result of the target respiratory event indicates that the target 0 ventilator has a respiratory event, determine that the target ventilator has a respiratory event. Thus, can

It is determined whether a respiratory event has occurred in the target ventilator within a preset time period from the dimension of the variance of the gas flow or the gas pressure.

Step 106, generating respiratory event alarm information in response to determining that a respiratory event has occurred in the target ventilator.

5 In some embodiments, the execution subject may generate respiratory event alarm information in response to determining that a respiratory event occurs in the target ventilator. Wherein, the above-mentioned respiratory event alarm information may be information representing the occurrence of a respiratory event by the target ventilator. For example, the above respiratory event alarm information may be "ventilator 001, a respiratory event occurs". The ventilator 001 may be the identifier of the above-mentioned target ventilator.

0 In some optional implementations of some embodiments, the above execution subject may generate respiratory event alarm information through the following steps:

In the first step, the product of the historical gas flow variance included in the historical operating parameter information and the second preset coefficient is determined as the hypopnea event threshold. Wherein, the above-mentioned second preset coefficient may be a preset value smaller than 1. Here, the second preset coefficient may be the same as the first preset coefficient.

Wherein, the above-mentioned third preset coefficient may be smaller than the above-mentioned second preset coefficient. For example, the above-mentioned third preset coefficient may be 0.2.

In a third step, in response to determining that the gas flow variance included in the operating parameter information is smaller than the apnea event threshold, determine the respiratory event type as an apnea event. Thus, it can be determined that an apnea event has occurred in the target ventilator within a preset time period when the variance of the gas flow rate is less than the apnea event threshold.

Step 4: In response to determining that the gas flow variance included in the operating parameter information is greater than the apnea event threshold and smaller than the hypopnea event threshold, determine the respiratory event type as a hypopnea event. Therefore, when the gas flow variance is greater than the apnea event threshold and less than the hypopnea event threshold, it can be determined that a hypopnea event has occurred in the target ventilator within a preset time period.

Step 5: In response to determining that the identification result of the above-mentioned target respiratory event indicates that the above-mentioned target ventilator has a snoring event, the type of the respiratory event is determined as a snoring event. In this way, it can be determined whether a snoring event has occurred through the recognition result of the target respiratory event.

Step 6: Generate respiratory event alarm information according to the determined respiratory event type.

Here, the matching relationship between the target number of respiratory events and the level of respiratory events may be: the target number of respiratory events is within the range of the number of respiratory events corresponding to the level of respiratory events. The respiratory event level may be the level of the number of respiratory events that occur after the target ventilator is turned on this time. The greater the number of respiratory events that occur, the higher the respiratory event grade. For example, the level of respiratory events corresponding to two respiratory events may be level two.

The fourth step is to determine the respiratory event alarm mode information set according to the determined respiratory event level. Wherein, the respiratory event alarm mode information in the respiratory event alarm mode information set includes alarm terminal type and alarm prompt mode information. In practice, the execution subject may select at least one preset respiratory event alarm mode information corresponding to the respiratory event level from the preset respiratory event alarm mode information set. Then, the selected preset respiratory event alarm mode information may be determined as a respiratory event alarm mode information set. For example, the preset respiratory event alarm method information corresponding to the secondary respiratory event level may include "alarm terminal type: mobile terminal, alarm prompt mode information: text message prompt", "alarm terminal type: speaker, alarm prompt mode information: sound alarm hint". "Mobile phone terminal" can mean that an alarm is issued on the mobile phone terminal corresponding to the target ventilator. The mobile terminal corresponding to the target ventilator may be the mobile terminal responsible for checking the target ventilator. "Text message prompt" may represent a text message for prompting.

The fifth step is to generate respiratory event alarm information according to the determined respiratory event type, the aforementioned respiratory event alarm mode information set, the updated target number of respiratory events, and the determined respiratory event level.

The first step is to determine the power-on time of the above-mentioned target ventilator in this power-on state.

In the second step, the ratio of the updated target number of respiratory events to the aforementioned power-on duration is determined as the respiratory event index.

The third step is to determine whether the aforementioned respiratory event index is greater than a preset respiratory event index. Here, the specific setting of the preset respiratory event index is not limited.

The fourth step is to generate respiratory event index alarm information in response to determining that the respiratory event index is greater than the preset respiratory event index. In practice, the executive body may combine the respiratory event index and the preset respiratory event index alarm prompt template into respiratory event index alarm information. For example, the preset respiratory event index alarm prompt template may be "the current respiratory event index is ___, which has exceeded the standard". Among them, the underlined part is to be filled with the respiratory event index. For example, when the respiratory event index is 6 and the preset respiratory event index is 5, the generated respiratory event index alarm information may be "the current respiratory event index is 6, which has exceeded the limit".

The fifth step is to combine the determined respiratory event type, the above-mentioned respiratory event alarm mode information set, the updated target number of respiratory events, the determined respiratory event level and the above-mentioned respiratory event index alarm information into respiratory event alarm information. In practice, the above-mentioned executive body can combine the determined respiratory event type, the above-mentioned respiratory event alarm mode information, the updated target number of respiratory event times, the determined respiratory event level, and the above-mentioned respiratory event index alarm information into a respiratory Event alarm information.

If the above factors are resolved, the effect of quickly knowing the operation status of the ventilator after starting up this time and adding an alarm method can be achieved. In order to achieve this effect, the present disclosure introduces a respiratory event level, and the respiratory event alarm mode information is determined through the respiratory event level. Different respiratory event levels correspond to different respiratory event alarm information, that is, different alarm terminal types and alarm prompt modes. Therefore, according to the generated respiratory event alarm operation information, an alarm prompt can be given in the form of sound broadcast or graphic display. Thus, an alarm mode is added. In addition, the respiratory event alarm operation information includes respiratory event type, target respiratory event number, respiratory event level, and respiratory event index alarm information, and the operation status of the target ventilator after this startup can be quickly known through the respiratory event alarm operation information. As a result, the method of alarming respiratory events is added, and the operation status of the ventilator after this start-up can be quickly known.

The above-mentioned embodiments of the present disclosure have the following beneficial effects: the number of false or delayed reports of respiratory events is reduced through the respiratory event alarm method of some embodiments of the present disclosure. Specifically, the reason for the large number of false or delayed reports of respiratory events is that respiratory events are detected directly from the dimension of expiratory volume, resulting in a greater impact on the accuracy of the boundary alarm threshold on the detection results, resulting in false respiratory events. Reported or postponed more times. Based on this, in the respiratory event alarm method of some embodiments of the present disclosure, firstly, the gas flow information set of the target ventilator within a preset time period is collected. Wherein, the gas flow information in the above gas flow information set includes gas flow and gas pressure. Thus, the gas flow information set can represent each gas flow and each gas pressure of the target ventilator within a period of time. Then, according to each gas flow rate and each gas pressure included in the gas flow information set, the operating parameter information of the target ventilator within the preset time period is generated. Thus, the operating parameter information can be used to determine whether a respiratory event has occurred in the target ventilator within a preset time period. Afterwards, the historical gas flow information set of the above-mentioned target ventilator within a preset historical time period is acquired. Wherein, the historical gas flow information in the above historical gas flow information set includes historical gas flow. Thus, the historical gas flow information set can represent the various historical gas flows of the target ventilator in the past period of time. Secondly, according to each historical gas flow amount included in the historical gas flow information set, historical operating parameter information of the target ventilator within the preset historical time period is generated. Thus, the historical operating parameter information can be used to compare and judge whether a breathing event has occurred in the target ventilator within a preset time period. Next, according to the above-mentioned operation parameter information and the above-mentioned historical operation parameter information, it is determined whether a respiratory event occurs in the above-mentioned target ventilator. Thus, it can be determined whether a respiratory event has occurred in the target ventilator within a preset time period through the generated operating parameter information and historical operating parameter information. Afterwards, in response to determining that a respiratory event has occurred in the target ventilator, respiratory event alarm information is generated. Thus, after it is determined that a respiratory event has occurred in the target ventilator within a preset time period, respiratory event alarm information for alarming can be generated. Finally, according to the above respiratory event alarm information, the associated alarm device is controlled to perform a respiratory event alarm operation. As a result, the medical staff can be reminded to arrive at the ventilator site as soon as possible through the respiratory event alarm operation of the alarm device. It is also because when judging whether a breathing event has occurred in the ventilator, the boundary alarm threshold is not directly judged through the gas flow, but the operating parameter information of the target ventilator in the above preset time period and the historical operating parameters in the historical time period.
