Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a method, apparatus, device, and storage medium for adjusting a ventilator. Background Technology

[0002] In modern clinical medicine, mechanical ventilation has become a common treatment for acute respiratory distress syndrome (ARDS), but there are currently no guidelines to standardize its setting. Existing ventilators use PEEP titration after lung recruitment to maintain alveolar patency, increase functional residual capacity, and improve ventilation-perfusion ratio, thereby improving oxygenation. However, excessively high PEEP can lead to adverse reactions such as alveolar overinflation and circulatory depression. PEEP setting also requires balancing alveolar patency and overinflation, thus necessitating frequent adjustments by medical professionals, which consumes a significant amount of time and energy. Therefore, there is an urgent need for ventilators to automatically monitor oxygenation targets to alleviate the time and energy burden on medical staff. Summary of the Invention

[0003] This invention provides a ventilator adjustment method, apparatus, device, and storage medium to solve the problem of ventilators automatically monitoring oxygenation targets, thereby reducing the time and effort required by medical staff.

[0004] A ventilator adjustment method, comprising: Obtain the inhaled oxygen concentration and positive end-expiratory pressure values ​​from the ventilator; Determine whether the inhaled oxygen concentration value and the positive end-expiratory pressure value have reached the oxygenation target, wherein the oxygenation target is the oxygen saturation target in the blood; If the inhaled oxygen concentration value and the positive end-expiratory pressure value do not reach the oxygenation target, the inhaled oxygen concentration value and / or the positive end-expiratory pressure value are adjusted according to the parameter values ​​in the preset correspondence table, wherein the preset correspondence table is a table for adjusting the corresponding parameter relationship between the inhaled oxygen concentration value and the positive end-expiratory pressure value. If the inhaled oxygen concentration and the positive end-expiratory pressure reach the oxygenation target, then maintain the current inhaled oxygen concentration and the positive end-expiratory pressure.

[0005] A ventilator adjustment device, comprising: The acquisition module acquires the inhaled oxygen concentration and positive end-expiratory pressure values ​​from the ventilator. The judgment module determines whether the inhaled oxygen concentration value and the positive end-expiratory pressure value have reached the oxygenation target according to a preset correspondence table. The preset correspondence table is a table that adjusts the relationship between the corresponding parameters of the inhaled oxygen concentration value and the positive end-expiratory pressure value. The oxygenation target is the oxygen saturation in the blood. The first processing module adjusts the inhaled oxygen concentration or the positive end-expiratory pressure (PEEP) value according to the parameter values ​​in the preset correspondence table if the inhaled oxygen concentration value or the PEEP value does not reach the oxygenation target. The second processing module maintains the current inhaled oxygen concentration and positive end-expiratory pressure values ​​if the inhaled oxygen concentration and positive end-expiratory pressure values ​​reach the oxygenation target.

[0008] The aforementioned ventilator adjustment method, apparatus, device, and storage medium acquire the inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​of the ventilator. Based on a preset correspondence table, it determines whether the inhaled oxygen concentration and PEEP values ​​have reached the oxygenation target. If the inhaled oxygen concentration and PEEP values ​​have not reached the oxygenation target, the inhaled oxygen concentration and / or PEEP values ​​are adjusted according to the parameters in the preset correspondence table. If the inhaled oxygen concentration and PEEP values ​​have reached the oxygenation target, the current inhaled oxygen concentration and PEEP values ​​are maintained.

Detailed Implementation

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] The ventilator adjustment method provided in this invention aims to determine whether the inhaled oxygen concentration and the positive end-expiratory pressure have reached the oxygenation target by using a preset correspondence table. It should be noted that, for ease of understanding of this invention, some terms involved in this invention will be briefly introduced below: The inhaled oxygen concentration (FiO2) value referred to in this application 2 Friction of inspiration O 2 Inhaled oxygen concentration (IOS) refers to the numerical value of oxygen concentration inhaled by the human body. For example, in the medical field, medical professionals use IOS to determine the amount of oxygen a patient is inhaling, which plays an important role in the treatment of patients with breathing difficulties and critically ill patients. According to FIO 2 The magnitude of the value helps medical professionals determine whether a patient needs timely oxygen therapy to increase the concentration of inhaled oxygen.

[0013] The positive end-expiratory pressure (PEEP) referred to in this application is the positive pressure applied when the airway is kept open during the use of a ventilator, which helps the patient's alveoli expand, increases the reduced functional residual capacity, and improves the oxygen concentration in the blood.

[0014] In this embodiment, as Figure 1 As shown, a ventilator adjustment method is provided, which is applied to... Figure 1 Taking the application in [the document] as an example, the following steps are included: S10: Obtain the inhaled oxygen concentration and positive end-expiratory pressure values ​​from the ventilator; S20: Determine whether the obtained inhaled oxygen concentration value and the positive end-expiratory pressure value have reached the oxygenation target, wherein the oxygenation target is the oxygen saturation target in the blood. Specifically, after a patient is connected to a ventilator, the ventilation mode is first activated to provide mechanical ventilation. After mechanical ventilation begins, the ventilator acquires the patient's current inhaled oxygen concentration and positive end-expiratory pressure (PEEP). The acquired oxygen concentration and PEEP values ​​are then evaluated to determine if they meet the oxygenation target. For example, an oxygenation target of 88% or higher is considered achieved; if it is below 88%, the target is not met. The oxygenation target described above is merely illustrative and not a specific limitation. Medical professionals can set the target according to medical industry standards or modify it based on the patient's condition. For example, the ventilator acquires an inhaled oxygen concentration of 0.3 and a PEEP of 5 cmH2O. 2 For O, the patient's 30% inhaled oxygen concentration and positive end-expiratory pressure are 5 cm H. 2 The system assesses whether the patient's inhaled oxygen concentration and positive end-expiratory pressure (PEEP) have reached the oxygenation target, specifically, an inhaled oxygen concentration of 0.3 and a PEEP of 5 cmH2O. 2 At 0, can the patient's oxygenation target reach more than 88%?

[0015] S30: If the inhaled oxygen concentration value and the positive end-expiratory pressure value do not reach the oxygenation target, the inhaled oxygen concentration value and / or the positive end-expiratory pressure value are adjusted according to the parameter values ​​in the preset correspondence table, wherein the preset correspondence table is a table for adjusting the corresponding parameter relationship between the inhaled oxygen concentration value and the positive end-expiratory pressure value. Specifically, as shown in Table 1, the preset correspondence table contains the adjustable positive end-expiratory pressure (PEEP) parameter corresponding to the adjustment of the inhaled oxygen concentration. When adjusting the inhaled oxygen concentration or PEEP, the ventilator will adjust according to the preset inhaled oxygen concentration and corresponding PEEP value. The values ​​in this table are only illustrative examples; the specific values ​​can be adjusted according to medical industry standards. In step S30, if the obtained inhaled oxygen concentration and PEEP values ​​do not reach the oxygenation target, the preset correspondence table parameters are retrieved to adjust the inhaled oxygen concentration and PEEP values. For example, if the ventilator obtains a patient inhaled oxygen concentration of 0.3 and a PEEP of 5 cmH2O, the ventilator will adjust these values ​​accordingly. 2 At 0, the patient's inhaled oxygen concentration and positive end-expiratory pressure (PEEP) were determined to have not met the oxygenation target, specifically, the patient's inhaled oxygen concentration was 0.3 and PEEP was 5 cmH2O. 2 If the patient's oxygenation target fails to reach 88% or higher at time 0, then the patient's inhaled oxygen concentration or positive end-expiratory pressure (PEEP) value should be adjusted. The above is merely an example and is not a specific limitation.

[0016] Table 1 PEEP-FiO 2 Correspondence table S40: If the inhaled oxygen concentration and the positive end-expiratory pressure reach the oxygenation target, then maintain the current inhaled oxygen concentration and positive end-expiratory pressure values.

[0017] Specifically, after mechanical ventilation, the latest inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​obtained from the ventilator are used to assess whether the oxygenation target has been achieved. If the oxygen concentration and PEEP values ​​are maintained, the latest values ​​are kept constant. For example, if the ventilator obtains an inhaled oxygen concentration of 0.3 and a PEEP of 5 cmH2O, the patient's oxygen concentration is maintained at 0.3 and the PEEP is 5 cmH2O. 2 At 0:00, the ventilator determined the patient's inhaled oxygen concentration to be 0.3 and positive end-expiratory pressure to be 5 cmH2O. 2 If the oxygenation target is achieved, meaning the patient's oxygenation can reach 88% or higher, then maintain the patient's current inhaled oxygen concentration of 0.3 and positive end-expiratory pressure of 5 cmH2O. 2 O.

[0018] In this embodiment, by acquiring the inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​from the ventilator, it is determined whether the acquired values ​​have reached the oxygenation target. If the values ​​have not reached the target, the inhaled oxygen concentration and / or PEEP are adjusted according to parameters in a preset correspondence table. If the values ​​have reached the target, the current values ​​are maintained. By using the parameters in the preset correspondence table, the ventilator can autonomously adjust the inhaled oxygen concentration and PEEP to achieve the oxygenation target, thereby saving time and effort for medical staff.

[0019] In this embodiment, as Figure 2 As shown, a ventilator adjustment method is provided. Step S20, which determines whether the acquired inhaled oxygen concentration and positive end-expiratory pressure values ​​have reached the oxygenation target, specifically includes the following steps: S21: Output the obtained inhaled oxygen concentration value and the positive end-expiratory pressure value; S22: Determine whether the output inhaled oxygen concentration value and the positive end-expiratory pressure value have reached the oxygenation target.

[0020] Specifically, after the ventilator acquires the patient's inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values, it outputs these values. The output values ​​are rounded to the nearest integer, and then evaluated to determine if they meet the target oxygenation level. For example, if the ventilator's most recent inhaled oxygen concentration is 0.32 and the PEEP is 4.5 cmH2O,... 2 If O, the output oxygen concentration value will be 0.3, and the positive end-expiratory pressure value will be 5 cm H. 2 O, and the patient was given an inhaled oxygen concentration of 0.3 and a positive end-expiratory pressure of 5 cm H⁺. 2Delayed monitoring is performed at time O. This delayed monitoring involves setting a preset delay time after acquiring the patient's most recent inhaled oxygen concentration and positive end-expiratory pressure (PEEP). The preset delay time can be set according to the patient's specific condition or by the hospital based on specific medical operating standards. The specific delay time is not limited. This delayed monitoring is used to determine whether the patient's inhaled oxygen concentration and PEEP have reached the oxygenation target, i.e., when the inhaled oxygen concentration is 0.3 and the PEEP is 5 cmH2O. 2 At 0, can the patient's oxygenation target reach more than 88%?

[0021] In this embodiment, a ventilator adjustment method is provided. For example... Figure 3 As shown, in step S30, the inhaled oxygen concentration and / or the positive end-expiratory pressure are adjusted according to the parameter values ​​in the preset correspondence table. This specifically includes the following steps: S31: If the oxygenation target is not achieved, the parameter values ​​in the preset correspondence table are retrieved to determine whether the current inhaled oxygen concentration and / or positive end-expiratory pressure can be adjusted. S32: If the current inhaled oxygen concentration and / or the positive end-expiratory pressure can be adjusted, then the current inhaled oxygen concentration and / or the positive end-expiratory pressure are adjusted, and the adjusted inhaled oxygen concentration and the positive end-expiratory pressure are judged and adjusted until the oxygenation target is reached.

[0022] Specifically, if the obtained inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​indicate that the oxygenation target has not been achieved, the inhaled oxygen concentration and PEEP values ​​will be retrieved from a preset correspondence table. The system will then determine whether the inhaled oxygen concentration or PEEP values ​​can be adjusted further based on these values. If adjustment is possible, the values ​​will be adjusted according to the preset adjustment range specified in the table. For adjustable inhaled oxygen concentration and PEEP values, the corresponding parameter values ​​will be added to the preset table each time. The specific value added each time is not explicitly set and can be adjusted according to medical industry standards. The adjusted inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​are evaluated to determine whether the oxygenation target can be achieved under these adjusted values. If not, the above steps are repeated to determine whether the inhaled oxygen concentration and PEEP values ​​can be adjusted further. If they can be adjusted, the adjustment continues until the oxygenation target is achieved.

[0023] For example, as shown in Table 1, if according to the preset correspondence table, the patient's inhaled oxygen concentration is 0.6 and the positive end-expiratory pressure is 12 cm H⁻¹ 2 At time O, if the patient's oxygenation target is not reached above 88%, the preset correspondence table is checked to determine if the inhaled oxygen concentration of 0.6 is already the maximum value in the table. If it is not the maximum value, the inhaled oxygen concentration can be further adjusted. If the oxygenation target is not reached after adjusting the inhaled oxygen concentration and the unadjusted positive end-expiratory pressure (PEAP), the PEAP value in the preset correspondence table is checked to determine if it is already the maximum value in the table. If it is not the maximum value, the PEAP can be further adjusted. If the positive end-expiratory pressure (PEEP) or inhaled oxygen concentration (IOP) value can be adjusted, the PEEP value is added according to a preset correspondence table. The values ​​are added sequentially from smallest to largest according to the preset correspondence table. When adjusting the PEEP value, only one value is adjusted at a time. That is, only the PEEP value can be adjusted at a time to determine the oxygenation target. If the oxygenation target has not been reached, another value is adjusted, and the oxygenation target is determined again. There is no specific restriction on the order in which the PEEP value is adjusted.

[0024] Assuming the initial adjusted inhaled oxygen concentration is 0.7, the unadjusted positive end-expiratory pressure (PEEP) needs to be adjusted to 12 cm H⁻¹. 2 O, determine if the oxygenation target can be achieved, specifically whether it can reach 88% or higher. If the oxygenation target is achieved, maintain an inhaled oxygen concentration of 0.7 and a positive end-expiratory pressure of 12 cm H⁻¹. 2 If the oxygenation target is not achieved after adjusting the oxygen inhalation concentration, the positive end-expiratory pressure (PEEP) should be adjusted. For example, if the PEEP is adjusted to 14 cmH2O,... 2 O, then the inhaled oxygen concentration value needs to be set to 0.7, and the adjusted positive end-expiratory pressure value to 14 cm H. 2 The oxygen concentration is then assessed to determine if the oxygenation target has been reached. If the target has been achieved, the inhaled oxygen concentration is maintained at 0.7 mmol / L, and the positive end-expiratory pressure is maintained at 14 cmH2O. 2 If the ventilator determines that the oxygenation target has not been reached, repeat steps S31-S32 until the oxygenation target is reached or the inhaled oxygen concentration and positive end-expiratory pressure cannot be adjusted.

[0025] In this embodiment, a breathing regulation method is provided. Before adjusting the inhaled oxygen concentration and / or the positive end-expiratory pressure (PEEP) value according to the parameter values ​​in the preset correspondence table in step S30, the method further includes the following steps: S33: Based on the values ​​of the positive end-expiratory pressure and the inhaled oxygen concentration, different preset correspondence tables are formed.

[0026] Specifically, in clinical patient care, different types of patients often emerge, and the degree of ventilator use required varies. Therefore, a pre-defined correspondence table is established based on the values ​​of positive end-expiratory pressure (PEEP) and inhaled oxygen concentration (IOP). This table includes, but is not limited to, four types of pre-defined correspondence tables: high PEEP and high IOP, high PEEP and low IOP, low PEEP and high IOP, and low PEEP and low IOP. Further detailed classifications can be made according to medical industry operating procedures; the specific classification is not limited. When adjusting oxygenation targets for different types of patients, different pre-defined correspondence tables are used based on the patient's classification. Based on different preset classification tables, different levels of treatment can be provided for different patients. The numerical parameters in the preset correspondence table can be pre-set in the ventilator according to medical treatment guidelines, or the corresponding parameter values ​​can be manually entered according to the patient's condition, making the ventilator more flexible and faster in treating patients and saving time in the treatment process.

[0027] In this embodiment, a breathing regulation method is provided. After step S30, i.e., adjusting the inhaled oxygen concentration and / or the positive end-expiratory pressure according to the parameter values ​​in the preset correspondence table, the method further includes the following steps: S34: When the inhaled oxygen concentration and / or positive end-expiratory pressure are adjusted to the maximum value according to the parameter values ​​in the preset correspondence table, and the oxygenation target has not yet been reached, an alarm message is sent to the medical terminal, and the current parameter values ​​of the inhaled oxygen concentration and positive end-expiratory pressure are maintained.

[0028] Specifically, if the patient's inhaled oxygen concentration and positive end-expiratory pressure are adjusted to the maximum values ​​in the corresponding relationship table, and the patient's oxygenation target has not yet reached 88%, the ventilator will send an alarm message through the medical terminal to notify medical staff to take emergency measures and change the patient's treatment strategy. While sending the alarm message to the doctor through the medical terminal, the maximum inhaled oxygen concentration and maximum positive end-expiratory pressure values ​​in the preset relationship table will be maintained until medical staff implement other treatment plans for the patient.

[0029] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0030] In this embodiment, a ventilator adjustment device is provided, which corresponds one-to-one with the ventilator adjustment method in the above embodiments. For example... Figure 4 As shown, the ventilator adjustment device includes an acquisition module, a judgment module, a first processing module, and a second processing module. Detailed descriptions of each functional module are as follows: The acquisition module is used to acquire the inhaled oxygen concentration and positive end-expiratory pressure values ​​of the ventilator. Specifically, after the patient is connected to a ventilator, the first step is to activate the ventilator's ventilation mode and begin mechanical ventilation. After mechanical ventilation begins, the ventilator acquires the patient's current inhaled oxygen concentration and positive end-expiratory pressure.

[0031] The judgment module is used to determine whether the inhaled oxygen concentration value and the positive end-expiratory pressure value have reached the oxygenation target according to a preset correspondence table. The preset correspondence table is a table that adjusts the relationship between the corresponding parameters of the inhaled oxygen concentration value and the positive end-expiratory pressure value. The oxygenation target is the oxygen saturation in the blood. Specifically, based on the obtained inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values, it is determined whether the oxygenation target has been reached. The oxygenation target is defined as above 88%. If it is below 88%, the oxygenation target has not been achieved. The above oxygenation target is merely illustrative and not a specific limitation. Medical professionals can set it according to medical industry standards or modify it based on the patient's condition.

[0032] The first processing module is used to adjust the inhaled oxygen concentration value or the positive end-expiratory pressure value according to the parameter values ​​in a preset correspondence table if the oxygenation target is not reached. Specifically, if the obtained values ​​of inhaled oxygen concentration and positive end-expiratory pressure do not meet the oxygenation target, the preset corresponding table parameters are retrieved to adjust the values ​​of inhaled oxygen concentration and positive end-expiratory pressure.

[0033] Optionally, the first processing module is further used for: If the oxygenation target is not achieved, the parameter values ​​in the preset correspondence table are retrieved to determine whether the current inhaled oxygen concentration and / or positive end-expiratory pressure can be adjusted. If the current inhaled oxygen concentration and / or positive end-expiratory pressure (PEEP) values ​​can be adjusted, then the current inhaled oxygen concentration and / or PEEP values ​​are adjusted, and the adjusted inhaled oxygen concentration and PEEP values ​​are judged and adjusted until the oxygenation target is achieved.

[0034] Specifically, if the obtained inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​indicate that the oxygenation target has not been achieved, the inhaled oxygen concentration and PEEP values ​​will be retrieved from a preset correspondence table. The system will then determine whether the inhaled oxygen concentration or PEEP values ​​can be adjusted further based on these values. If adjustment is possible, the values ​​will be adjusted according to the preset adjustment range specified in the table. For adjustable inhaled oxygen concentration and PEEP values, the corresponding parameter values ​​will be added to the preset table each time. The specific value added each time is not explicitly set and can be adjusted according to medical industry standards. The adjusted inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​are evaluated to determine whether the oxygenation target can be achieved under these adjusted values. If not, the above steps are repeated to determine whether the inhaled oxygen concentration and PEEP values ​​can be adjusted further. If they can be adjusted, the adjustment continues until the oxygenation target is achieved.

[0035] Optionally, the first processing module is further used for: Based on the values ​​of positive end-expiratory pressure and inhaled oxygen concentration, different preset correspondence tables are used.

[0036] Specifically, in clinical patient care, different types of patients often emerge, and the degree of ventilator use required varies. Therefore, a pre-defined correspondence table is established based on the values ​​of positive end-expiratory pressure (PEEP) and inhaled oxygen concentration (IOP). This table includes, but is not limited to, four types of pre-defined correspondence tables: high PEEP and high IOP, high PEEP and low IOP, low PEEP and high IOP, and low PEEP and low IOP. Further detailed classifications can be made according to medical industry operating procedures; the specific classification is not limited. When adjusting oxygenation targets for different types of patients, different pre-defined correspondence tables are used based on the patient's classification. Based on different preset classification tables, different levels of treatment can be provided for different patients. The numerical parameters in the preset correspondence table can be pre-set in the ventilator according to medical treatment guidelines, or the corresponding parameter values ​​can be manually entered according to the patient's condition, making the ventilator more flexible and faster in treating patients and saving time in the treatment process.

[0037] Optionally, the first processing module is further used for: When the inhaled oxygen concentration and / or positive end-expiratory pressure are adjusted to their maximum values ​​according to the parameter values ​​in the preset correspondence table, and the oxygenation target has not yet been reached, an alarm message is sent to the medical terminal, and the current parameter values ​​of the inhaled oxygen concentration and positive end-expiratory pressure are maintained.

[0038] Specifically, if the patient's inhaled oxygen concentration and positive end-expiratory pressure are adjusted to the maximum values ​​in the corresponding relationship table, and the patient's oxygenation target has not yet reached 88%, the ventilator will send an alarm message through the medical terminal to notify medical staff to take emergency measures and change the patient's treatment strategy. While sending the alarm message to the doctor through the medical terminal, the maximum inhaled oxygen concentration and maximum positive end-expiratory pressure values ​​in the preset relationship table will be maintained until medical staff implement other treatment plans for the patient.

[0039] The second processing module is used to maintain the current inhaled oxygen concentration and positive end-expiratory pressure values ​​if the inhaled oxygen concentration and positive end-expiratory pressure values ​​reach the oxygenation target.

[0040] Specifically, after mechanical ventilation, the latest inhaled oxygen concentration and positive end-expiratory pressure (PEEP) values ​​obtained from the ventilator are used to determine whether the oxygenation target has been achieved. If the oxygenation target has been reached, the latest inhaled oxygen concentration and PEEP values ​​are maintained.
