In one embodiment, a method for adjusting pressure is provided, and this embodiment relates to a specific process of adjusting output pressure according to ventilation area parameters, as shown in fig. 2, where the method is used in a ventilator, and the ventilator includes a ventilation circuit, and the method is applied to the electronic device in fig. 1, and may include the following steps:
s202, acquiring ventilation area data of the tail end of the ventilation pipeline.
The tail end of the ventilation pipeline refers to the tail end of a ventilator ventilation pipeline, and the ventilator ventilation pipeline is used for conveying gas output by a ventilator. The ventilation area data refers to the ventilation area of the line end, and may specifically be a curve of the ventilation area over time. The ventilation area is the area of the effective ventilation area that the opening or mouthpiece at the end of the tubing in the ventilation system has, where gas enters or leaves the ventilation tubing, typically in connection with the patient's respiratory mouthpiece or endotracheal tube. The acquired ventilation area data may be data of an instant time or average data of a period of time, which is not particularly limited in this embodiment.
Further, when the ventilation area data of the ventilation pipeline end is acquired, the ventilation area of the pipeline end can be calculated according to the gas flow rate and the gas pressure by installing a sensor at the pipeline end and acquiring the gas flow rate and the gas pressure of the pipeline end. The calculation process may be performed by electronics in the ventilator device. Alternatively, the pipeline system is modeled and simulated using hydrodynamic simulation software, and the ventilation area of the pipeline end is obtained, and the simulation process can be completed by electronic equipment in the breathing machine. Alternatively, other modes may be adopted, and this embodiment is not particularly limited thereto.
Specifically, the ventilation area is calculated according to the gas data of the tail end of the pipeline, and the electronic equipment acquires the ventilation area data of the tail end of the ventilation pipeline. The electronic device may be a single chip microcomputer, a microcontroller, etc.
S204, determining the breathing type of the user currently using the breathing machine according to the ventilation area data.
The ventilator is a medical device, and is generally used for supporting respiratory functions of a patient, and the ventilator device can enter the lung of the patient through air supply to assist or completely control respiration, and is generally used for intensive care, operation or the condition of insufficient respiration of the patient. The breathing type refers to a type of breathing corresponding to a user when using the ventilator, such as deep breathing, shallow breathing, chest breathing, rhythmic breathing, sudden breathing, and the like.
Further, the ventilation area data is the ventilation area of the tail end of the pipeline of the breathing machine, and the breathing type of the user currently using the breathing machine is determined according to the ventilation area data, so that the ventilation area data under different breathing types can be matched with the ventilation area data obtained by current calculation, and the breathing type corresponding to the current ventilation area data can be obtained. Alternatively, the ventilation area data may be classified, and the current ventilation area data may be input into a classification model to obtain a breathing type corresponding to the current ventilation area data. Alternatively, other modes may be adopted, and this embodiment is not particularly limited thereto.
Specifically, after the ventilation area data of the ventilation line end is obtained, the breathing type of the user currently using the ventilator is determined according to the ventilation area data of the ventilation line end.
S206, adjusting the gas pressure output by the breathing machine according to the breathing type.
The pressure of the gas output by the breathing machine refers to the level of the gas generated when the breathing machine delivers the gas to a patient in the ventilation process, and the pressure is controlled and regulated by the breathing machine to ensure that the lungs of the patient can be fully inflated, so that the gas exchange is effectively performed. Different breath types require corresponding adjustments in the ventilator output gas pressure, such as deep breath types may require higher output pressures and superficial breath types may require lower output pressures.
Further, the air pressure output by the ventilator is adjusted according to the breathing type, which may be that the electronic device stores reference output air pressures corresponding to different breathing types, and after the electronic device obtains the breathing type, the electronic device confirms the corresponding reference output air pressure according to the breathing type, and then controls the fan of the ventilator to adjust the air pressure output by the ventilator to the corresponding reference output air pressure. Or, the output quantity to be adjusted can be calculated according to the breathing type, and the output gas pressure corresponding to the current breathing type can be adjusted according to the output quantity. Alternatively, other modes are possible, and the present embodiment is not particularly limited thereto.
Specifically, after the breath type of the user when using the ventilator is obtained, the gas pressure output by the ventilator is adjusted according to the breath type.
According to the pressure regulating method, the ventilation area data of the tail end of the ventilation pipeline is obtained, the breathing type of the user currently using the breathing machine is determined according to the ventilation area data, and then the gas pressure output by the breathing machine is regulated according to the breathing type. According to the method, through acquiring ventilation area data of the tail end of the ventilation pipeline, the breathing type of a user can be determined according to the ventilation area data, so that different ventilation area data can be corresponding to different breathing types of the user, then when the gas pressure output by the breathing machine is regulated according to the breathing type, the corresponding regulation can be carried out according to different breathing types, the flexible regulation of the output gas pressure of the breathing machine is realized, compared with the traditional mode of regulating the output pressure by adopting the amplitude of the vibration data of the pipeline airflow, the single regulation of the output pressure is avoided, in addition, the pressure regulation is not influenced by pipeline materials and pipeline resonance, the regulation of the output pressure under different conditions can be flexibly adapted, and the output pressure of the breathing machine can be flexibly regulated.
The above examples refer to the possibility of acquiring ventilation area data of the end of the ventilation line, and the following examples describe one embodiment of how ventilation area data may be acquired.
In another embodiment, another pressure adjusting method is provided, and based on the above embodiment, as shown in fig. 3, the step S202 may include the following steps:
s302, collecting ventilation areas of the tail ends of the ventilation pipelines at intervals of preset time periods in a target sampling period to obtain a plurality of ventilation areas.
The target sampling period refers to a period of time after the user starts to use the ventilator, such as 10 minutes, 20 minutes, etc., and the multiple target sampling periods may be multiple consecutive periods. In addition, the preset duration is to segment the target sampling period, which refers to a shorter time interval, such as 1 second, 5 seconds, etc.
Further, the ventilation area of the ventilation line end is acquired every preset time period in the target sampling period, that is, every other time period after the user starts to use the ventilator, that is, the ventilation area of the ventilation line end per second in the time period is acquired in the target sampling period, and then, the ventilation area of the ventilation line end per second in the next target sampling period is acquired again. Further, when the ventilation area of the ventilation pipeline end is collected at intervals of a preset time period, the ventilation area may be collected by a collection unit in the electronic device, or may be collected by other manners, which is not specifically limited in this embodiment.
Specifically, in the target sampling period, the ventilation area of the tail end of the ventilation pipeline is acquired every preset time length, and a plurality of ventilation area values in the target sampling period are obtained.
Illustratively, 10 minutes after the user begins to use the ventilator, the ventilation area of the ventilation circuit tip per second is acquired for 10 minutes, and 600 ventilation area values are acquired.
S304, generating a ventilation area curve based on the plurality of ventilation areas, and taking the ventilation area curve as ventilation area data.
The ventilation area curve refers to a change curve of a ventilation area with time, and a horizontal axis of the ventilation area curve is time, and a unit of time is the preset duration, for example, may be seconds, and a vertical axis is a ventilation area value.
Specifically, according to the plurality of ventilation areas obtained in the target sampling period, a change curve of each preset duration corresponding to the ventilation area is generated by taking the preset duration as a horizontal axis and the ventilation area at the tail end of the ventilation pipeline as a vertical axis, so as to obtain a ventilation area curve, and the ventilation area curve is used as ventilation area data.
In this embodiment, a plurality of ventilation areas are obtained by collecting ventilation areas of the ventilation line end at intervals of a preset duration in the target sampling period, and then a ventilation area curve is generated based on the plurality of ventilation areas, and the ventilation area curve is used as ventilation area data. The ventilation area is acquired in the target sampling period, the ventilation area curve is generated, the corresponding ventilation area curve in different target sampling periods can be obtained, and the ventilation area curve is used as ventilation area data, so that the change condition of the ventilation area in different periods can be reflected in real time.
The above embodiments have mentioned that the breathing type of the user currently using the ventilator may be determined from ventilation area data, and the following embodiments describe how the breathing type is determined.
In another embodiment, as shown in fig. 4, the step S204 may include the following steps:
s402, acquiring smoothness data of a ventilation area curve.
The smoothness data refers to the smoothness of the ventilation area curve, the smoothness data of the ventilation area curve can reflect the change degree of the ventilation area curve, specifically, the smoothness can be represented by the absolute value of the slope of the ventilation area curve in a period of time, the smaller the absolute value of the slope is, the flatter the curve is, and when the slope is 1, the flattest ventilation area curve is represented, that is, the ventilation area curve is parallel to the transverse axis, and the ventilation area curve is not changed any more. Alternatively, the degree of smoothness may be a value of the difference between the ventilation area values corresponding to a plurality of consecutive times in the period, and if the difference between the ventilation area at the current time and the ventilation area at the previous time is small, it is considered that the ventilation area curve does not change or changes little.
Specifically, after the ventilation area data is obtained, the smoothness data in the current time period is calculated according to the ventilation area curve.
S404, determining the breathing type of the user according to the flattening data.
In this step, since the smoothness data can reflect the change condition of the ventilation area curve, when the smoothness is high, the ventilation area curve is flatter, the curve change degree is smaller, and when the smoothness is low, the ventilation area curve is less flat, and the curve change degree is larger. When determining the breathing type of the user according to the smoothness data, as an optional embodiment, if the smoothness data indicates that the smoothness of the ventilation area curve is less than or equal to a preset smoothness threshold, determining that the breathing type of the user is an abnormal breathing type, and if the smoothness data indicates that the smoothness of the ventilation area curve is greater than the preset smoothness threshold, determining that the breathing type of the user is a normal breathing type.
The preset smoothness threshold may be an absolute slope value of the ventilation area curve in a period of time, or may be an absolute ventilation area value in a period of time, if the absolute slope value of the ventilation area curve is used as smoothness data, the preset smoothness threshold is a preset absolute slope value, and if the difference of the ventilation area values is used as smoothness data, the preset smoothness threshold is a preset difference. In addition, the normal breathing type refers to a breathing type in which sudden breathing changes do not occur to the user, and the abnormal breathing type refers to a breathing type in which sudden breathing changes occur to the user.
Further, taking the absolute value of the slope of the ventilation area curve as the smoothness data as an example, when the smoothness of the ventilation area curve in a period of time is greater than a preset smoothness threshold, that is, the absolute value of the slope of the ventilation area curve in a period of time is greater than the preset absolute value of the slope, it indicates that the change rate of the ventilation area curve is higher, and at this time, it indicates that the ventilation area is changed normally along with the breathing of the user, and then it can be confirmed that the breathing type of the user is the normal breathing type. Similarly, when the smoothness of the ventilation area curve in a period of time is less than or equal to a preset smoothness threshold, that is, the absolute value of the slope of the ventilation area curve in a period of time is less than or equal to the absolute value of the slope, the change rate of the ventilation area curve is lower, at this time, the ventilation area is unchanged, and it can be confirmed that the breathing type of the user is an abnormal breathing type.
After determining that the breathing type of the user is the normal breathing type, the normal breathing type of the user can be displayed in a display interface of the breathing machine, that is, the "normal breathing" is output in real time in the display interface.
Specifically, after the ventilation area data is obtained, the smoothness data of the ventilation area curve is obtained, whether the ventilation area curve changes is confirmed according to the smoothness data, and then the breathing type of the user is further determined. Optionally, if the smoothness data indicates that the smoothness of the ventilation area curve is less than or equal to a preset smoothness threshold, determining that the breathing type of the user is an abnormal breathing type, and if the smoothness data indicates that the smoothness of the ventilation area curve is greater than or equal to the preset smoothness threshold, determining that the breathing type of the user is a normal breathing type.
Illustratively, when the ventilation area curve does not change within 10 seconds, the user's breathing type is considered to be an abnormal breathing type.
In this embodiment, the smoothness data of the ventilation area curve is acquired, and the breathing type of the user is determined according to the smoothness data. The breathing type of the user is determined by the smoothness data of the ventilation area curve, the breathing type can be accurately distinguished, and the breathing type can be determined in time because the ventilation area curve is generated in real time. Optionally, if the smoothness data indicates that the smoothness of the ventilation area curve is less than or equal to a preset smoothness threshold, determining that the breathing type of the user is an abnormal breathing type; if the smoothness data indicates that the smoothness of the ventilation area curve is greater than a preset smoothness threshold, determining that the breathing type of the user is a normal breathing type. The breath type is determined by the smoothness data and the preset smoothness threshold value, so that the breath type of the user can be accurately distinguished.
The above embodiments have mentioned that the breathing type of the user can be determined from the ventilation area data, and the following embodiments describe how the process of determining the breathing type of the user is further followed by determining the breathing type as an abnormal breathing type.
In another embodiment, as shown in fig. 5, another pressure adjusting method is provided, and the step S404 may include the following steps, based on the above embodiment:
s502, acquiring a current respiratory area value of the tail end of the ventilation pipeline according to the ventilation area curve.
In this step, the current respiratory area value refers to a respiratory area value corresponding to the current moment, and if the respiratory type is confirmed to be an abnormal respiratory type in a period of time, the respiratory area value at the last moment in the period of time is correspondingly obtained, or the average respiratory area value in the period of time is used as a respiratory parameter when the current user breathes abnormally, and according to the current respiratory parameter, the specific respiratory type of the user when the user breathes abnormally can be further confirmed. In addition, the current respiratory area value may be stored after the current respiratory area value is acquired.
Specifically, after the breathing type of the user is determined to be the abnormal breathing type according to the ventilation area curve, the current breathing area value of the tail end of the ventilation pipeline is obtained according to the ventilation area curve.
S504, comparing the current respiratory area value with ventilation area parameters corresponding to different respiratory types, and determining a target respiratory type of abnormal respiratory type according to the comparison result, wherein the different respiratory types comprise central apnea and obstructive apnea.
The ventilation area parameter refers to a common ventilation area value, and here may be a ventilation area value corresponding to a different breathing type of other users, for example, a common ventilation area value corresponding to central apnea and a common ventilation area value corresponding to obstructive apnea. The different respiratory types include central apneas and obstructive apneas, and the target respiratory type is any one of central apneas and obstructive apneas. In addition, the ventilation area parameters include central apneas and obstructive apneas.
Further, the ventilation area parameter may be a ventilation area value corresponding to the current user when abnormal breathing occurs, in addition to a general ventilation area value, and the ventilation area parameter may be updated and corrected. In addition, when the ventilation area parameter is a general ventilation area value, it is generally a parameter that is used when the user first starts to use the ventilator to determine the breathing type in the early stage, and when the user uses the ventilator in the middle-late stage, the updated ventilation area parameter may be used to determine the breathing type.
Further, in the early stage of the first use of the ventilator by the user, when determining the target respiratory type according to the current respiratory area value, the current respiratory area value can be compared with ventilation area values corresponding to different general respiratory types, and if the current respiratory area value is greater than the general ventilation area value corresponding to the central apnea type, the target respiratory type corresponding to the current respiratory area value is determined to be the central apnea; and if the current respiratory area value is larger than the universal ventilation area value corresponding to the obstructive apnea type, determining that the target respiratory type corresponding to the current respiratory area value is obstructive apnea.
Further, after determining the breathing type of the user when abnormal breathing occurs in the earlier stage, as an optional embodiment, the current breathing area value is stored, so as to adjust the ventilation area parameter corresponding to the target breathing type according to the stored current breathing area value. And if the target respiratory class corresponding to the current respiratory area value is determined to be the central apnea, updating the universal ventilation area value corresponding to the central apnea by using the current respiratory area value, and if the target respiratory class corresponding to the current respiratory area value is determined to be the obstructive apnea, updating the universal ventilation area value corresponding to the obstructive apnea by using the current respiratory area value. And taking the updated ventilation area value corresponding to the central apnea and the ventilation area value of the obstructive apnea as updated ventilation area parameters.
Further, in the middle-late stage of using the breathing machine by the user, when determining the target breathing type according to the current breathing area value, the current breathing area value can be compared with the ventilation area value included in the updated ventilation area parameter, and if the current breathing area value is greater than or equal to the updated ventilation area value corresponding to the central apnea type, the target breathing type corresponding to the current breathing area value is determined to be the central apnea; and if the current respiratory area value is greater than or equal to the updated respiratory area value corresponding to the obstructive apnea type, determining that the target respiratory type corresponding to the current respiratory area value is obstructive apnea. After the target breathing type is determined, as an alternative embodiment, the ventilator output gas pressure is adjusted if the target breathing type is determined to be obstructive apneas. Because obstructive apneas refer to apneas due to airway obstruction, the output gas pressure of the ventilator is adjusted to provide sufficient flow to the patient to overcome the airway obstruction and ensure that the patient continues to breathe.
Further, in the middle-late stage of using the breathing machine, after determining a target breathing type according to the breathing area value, the breathing area value corresponding to each target breathing type is stored, and then the ventilation area parameter is corrected and updated, specifically, each breathing area value is averaged, and the final breathing area average value is taken as the ventilation area value in the ventilation area parameter.
After determining that the breathing type of the user is an abnormal breathing type and determining that the target breathing type of the user is central apnea or obstructive apnea, the target breathing type of the user can be displayed in a display interface of the breathing machine, and if the target breathing type of the user is central apnea, the central apnea is output in real time in the display interface. In the case of obstructive apneas, the "obstructive apneas" are output in real-time in a display interface. Thus, any of "normal breathing", "central apnea" and "obstructive apnea" can be displayed in real time on the display interface of the ventilator.
Specifically, after the respiratory type is determined to be the abnormal respiratory type according to the ventilation area curve, the current respiratory area value of the tail end of the ventilation pipeline is obtained according to the ventilation area curve, the current respiratory area value is compared with ventilation area parameters corresponding to different respiratory types according to the current respiratory area value, and the target respiratory type of the abnormal respiratory type is determined according to the comparison result, wherein the different respiratory types comprise central apnea and obstructive apnea. After the target respiratory type is determined, storing the current respiratory area value so as to adjust the ventilation area parameter corresponding to the target respiratory type according to the stored current respiratory area value.
In this embodiment, the current respiratory area value of the end of the ventilation pipeline is obtained according to the ventilation area curve, and then the current respiratory area value is compared with ventilation area parameters corresponding to different respiratory types, and the target respiratory type of the abnormal respiratory type is determined according to the comparison result, wherein the different respiratory types include central apnea and obstructive apnea. The current breathing area value is compared with the ventilation area parameters corresponding to different breathing types to determine the target breathing types of the abnormal breathing types, different target breathing types can be accurately distinguished, and the mode of judging the target breathing types through the current breathing area value is not influenced by the material of the breathing pipeline and the gas oscillation, so that different target breathing types can be accurately identified. Further, the current respiratory area value is stored, so that the ventilation area parameter corresponding to the target respiratory type is adjusted according to the stored current respiratory area value. The ventilation area parameter is adjusted by using the current breathing area value, so that the ventilation area parameter is more close to the ventilation area parameter of the user, and the situation that the breathing type is misjudged due to the fact that a single general parameter is not applicable to the individual user is avoided, and the accuracy of determining the breathing type is effectively improved. Further, if the target respiratory species is determined to be obstructive apneas, the ventilator output gas pressure is adjusted. The output pressure can be adjusted in time when the obstructive apnea occurs by adjusting the obstructive apnea condition, so that the output pressure of the breathing machine can be flexibly adjusted.
The above embodiments have mentioned that the gas pressure output from the ventilator can be adjusted according to the type of breathing, and the following embodiments describe how to adjust the gas pressure.
In another embodiment, as shown in fig. 6, another pressure adjusting method is provided, and the step S206 may include the following steps, based on the above embodiment:
s602, acquiring the first gas pressure currently output by the breathing machine and the breathing duration of the obstructive apnea of the user.
The first gas pressure refers to output gas pressure at the tail end of a pipeline of the breathing machine when a user is in obstructive apnea, the first gas pressure can be obtained by installing a pressure sensor at the tail end of the pipeline, the pressure sensor transmits real-time pressure data to electronic equipment, and the electronic equipment can obtain the first gas pressure which is output currently. In addition, the respiratory duration refers to a duration of the obstructive apnea of the user, specifically, when it is determined that abnormal respiration occurs to the user, timing is started to obtain the respiratory duration of the obstructive apnea of the user, where the respiratory duration may be in units of seconds or milliseconds, and this embodiment is not limited specifically.
Specifically, after the target respiratory type of the user is determined to be obstructive apnea, the first gas pressure currently output by the breathing machine and the breathing duration of the obstructive apnea of the user are obtained.
S604, determining a second gas pressure according to the first gas pressure and the breathing time.
In this step, the second gas pressure is the gas pressure that the ventilator circuit end needs to output. The second gas pressure is determined according to the first gas pressure and the breath duration, specifically, the gas pressure increment is determined according to the first gas pressure and the breath duration, see formula (1).
Formula (1)
Wherein,for the pressure to be raised->For the first gas pressure->For breath duration, the constants 1.241, coefficients 0.023 and 0.145 were derived from analysis of historical experimental data and summary of experimental results. When->When the value of (2) is larger, < + >>Is of negative increment, when->When the value of (2) is small, < + >>Is a positive increment.
After the gas pressure increase is obtained, a second gas pressure can be calculated by referring to equation (2)。
Formula (2)
Specifically, a gas pressure increment is calculated according to the first gas pressure and the breathing duration, and the gas pressure increment is summed with the first gas pressure to obtain the second gas pressure.
S606, adjusting the gas pressure output by the breathing machine to be the second gas pressure.
In this step, the gas pressure output from the ventilator may be adjusted to the second gas pressure by adjusting the output pressure at the end of the pipeline in accordance with the relationship between the gas pressure output at the end of the pipeline and the rotational speed of the ventilator. Specifically, whether the gas pressure increment is a positive increment or a negative increment is judged first, if the gas pressure increment is positive, the electronic equipment controls a fan in the breathing machine to increase the rotating speed so as to increase the gas pressure output by the breathing machine, and if the gas pressure increment is negative, the electronic equipment controls the fan in the breathing machine to decrease the rotating speed so as to decrease the gas pressure output by the breathing machine until the gas pressure at the tail end of a pipeline of the breathing machine reaches the second gas pressure. Or, the first gas pressure and the second gas pressure can be judged first, if the first gas pressure is larger than the second gas pressure, the electronic equipment controls the fan in the breathing machine to reduce the rotating speed so as to reduce the gas pressure output by the breathing machine, and if the first gas pressure is smaller than the second gas pressure, the electronic equipment controls the fan in the breathing machine to increase the rotating speed so as to increase the gas pressure output by the breathing machine until the gas pressure at the tail end of the pipeline of the breathing machine reaches the second gas pressure.
Specifically, after the first gas pressure and the second gas pressure of the ventilator are obtained, the gas pressure output by the ventilator is adjusted from the first gas pressure to the second gas pressure according to the values of the first gas pressure and the second gas pressure.
In this embodiment, the first gas pressure currently output by the ventilator and the respiratory duration of the obstructive apnea of the user are obtained, the second gas pressure is determined according to the first gas pressure and the respiratory duration, and then the gas pressure output by the ventilator is adjusted to the second gas pressure. The second gas pressure is determined according to the first gas pressure and the breathing duration, so that the value of the gas pressure to be adjusted can be accurately determined, then the gas pressure output by the breathing machine is adjusted to be the second gas pressure, different output pressures can be adjusted to be the second gas pressure, and flexible adjustment of the output pressure of the breathing machine can be realized by adopting the adjusting mode.
