[0025] The technical solutions in the embodiments of the application will be described clearly and completely in the following with reference to the drawings of the embodiments of the application. Obviously, the described embodiments are only some embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0026] The application provides a target object-based mechanical ventilation management method. In an embodiment, as shown in Figure 1 The technical solution mainly includes the following steps:

[0027] S10, obtaining a preset mechanical ventilation parameter, and inputting the mechanical ventilation parameter into a ventilator to control the ventilator to run in a target ventilation mode corresponding to the mechanical ventilation parameter.

[0028] It can be understood that the mechanical ventilation parameters refer to a series of values and indexes set and adjusted when using a ventilator for mechanical ventilation treatment, such as ventilation mode, breathing frequency, etc.

[0029] Specifically, when the target object is a chest trauma, preset mechanical ventilation parameters corresponding to the target object of the chest trauma are obtained, and the mechanical ventilation parameters are input into the ventilator to control the ventilator to operate in a target ventilation mode corresponding to the mechanical ventilation parameters, that is, after the parameters of the ventilator are set, mechanical ventilation is started. For example, the ventilation mode is selected as continuous control ventilation (A / C, i.e., assisted or controlled), which can be volume control (VCV, Volume Control Ventilation) or pressure control (PCV), VT (tidal volume) is 6 to 8 ml / kg IBM (standard body weight), breathing frequency is 15 times / min, Ti (inspiration time) is less than or equal to 1 s, and PEEP (positive end-expiratory pressure) is 5 cmH20. Among them, the machine defaults to PCV mode, VT 6 ml / kg IBM, breathing frequency 15 times / min, inspiration time 1 s, and PEEP set to 5 cmH2O.

[0030] S20, pulse blood oxygen saturation detection is performed on the target object applied to the ventilator operating in the target ventilation mode to obtain a blood oxygen detection result.

[0031] It can be understood that the target object refers to a person who needs to be mechanically ventilated and whose parameter information is abnormal. The blood oxygen detection result is used to represent whether the pulse blood oxygen saturation is within a preset blood oxygen range. Pulse blood oxygen saturation (SpO2 for short) refers to the percentage of the oxygenation degree of hemoglobin, that is, the percentage of the oxygen concentration of hemoglobin to the capacity of hemoglobin.

[0032] Specifically, after starting mechanical ventilation, pulse blood oxygen saturation detection is performed on the target object applied to the ventilator operating in the target ventilation mode, that is, the pulse blood oxygen saturation of the target object is detected by the blood oxygen detection device, so as to obtain the pulse blood oxygen saturation of the target object. Then, a preset blood oxygen range corresponding to the target object is obtained, and the preset blood oxygen range and the pulse blood oxygen saturation of the target object are compared in size, so as to obtain a blood oxygen detection result for representing whether the pulse blood oxygen saturation is within the preset blood oxygen range.

[0033] S30, when the blood oxygen detection result represents that the pulse blood oxygen saturation is within the preset blood oxygen range, the inhaled oxygen concentration of the target object is detected to obtain a concentration detection result.

[0034] Understandably, the concentration detection result is used to represent the size relationship between the inhaled oxygen concentration and the preset inhaled oxygen threshold value. The inhaled oxygen concentration, namely FIO2, refers to the concentration of inhaled oxygen of the target object. The preset blood oxygen range refers to the range limit value of the pulse blood oxygen saturation set in advance.

[0035] Specifically, after obtaining the blood oxygen detection result, when the blood oxygen detection result represents that the pulse blood oxygen saturation is within the preset blood oxygen range, the inhaled oxygen concentration of the target object is detected, that is, the inhaled oxygen concentration of the target object is measured by a professional detection device, so as to obtain the inhaled oxygen concentration. Then, the preset inhaled oxygen threshold value corresponding to the target object is retrieved, and the inhaled oxygen concentration of the target object and the preset inhaled oxygen threshold value are compared in size, so as to obtain the concentration detection result used to represent the size of the inhaled oxygen concentration and the preset inhaled oxygen threshold value. When the blood oxygen detection result represents that the pulse blood oxygen saturation is out of the preset blood oxygen range, the inhaled oxygen concentration is adjusted so that the pulse blood oxygen saturation is within the preset blood oxygen range, and then the inhaled oxygen concentration detection is performed.

[0036] S40, when the concentration detection result represents that the inhaled oxygen concentration is less than the preset inhaled oxygen threshold value, the plateau pressure of the target object is detected to obtain a plateau pressure detection result.

[0037] Understandably, the preset inhaled oxygen threshold value refers to the limit value of the inhaled oxygen concentration corresponding to the target object set in advance. The plateau pressure detection result is used to represent the size relationship between the plateau pressure and the target plateau pressure. The plateau pressure, namely Pplat, refers to the airway pressure when the airflow at the end of inspiration stops.

[0038] Specifically, after obtaining the concentration detection result, when the concentration detection result represents that the inhaled oxygen concentration is less than the preset inhaled oxygen threshold value, the plateau pressure of the target object is detected, that is, the plateau pressure of the target object is measured multiple times by the detection device, and the average value is calculated, so as to obtain the plateau pressure of the target object. Then, the target plateau pressure corresponding to the target object is obtained, and the target plateau pressure and the plateau pressure of the target object are compared in size, so as to obtain the plateau pressure detection result used to represent the size of the plateau pressure and the target plateau pressure. When the concentration detection result represents that the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, a preset processing mode is used for processing.

[0039] S50, when the plateau pressure detection result represents that the plateau pressure is greater than the target plateau pressure, the tidal volume of the target object is controlled to decrease to a preset minimum level at a preset speed, and the respiratory frequency of the target object is gradually increased to maintain the minute ventilation unchanged, so that the plateau pressure is less than or equal to the target plateau pressure.

[0040] Understandably, the target platform pressure refers to a limit value of the platform pressure corresponding to the target object, for example, 30 cmH2O. The preset speed refers to the speed of reducing the tidal volume. The preset minimum level refers to the minimum tidal volume corresponding to the target object. The tidal volume refers to the volume of gas inhaled or exhaled each time during calm breathing. The respiratory rate refers to the number of breaths per minute.

[0041] Specifically, after obtaining the platform pressure detection result, when the platform pressure detection result represents that the platform pressure is greater than the target platform pressure, the tidal volume of the target object is controlled to be reduced to the preset minimum level at the preset speed, and at the same time, the respiratory rate of the target object is gradually increased to maintain the minute ventilation unchanged, so that the platform pressure is less than or equal to the target platform pressure. For example, if the platform pressure is greater than 30 cmH2O, the tidal volume is gradually reduced to the preset minimum level of 4 ml / kg at a gradient of 1 ml / kg, and after the tidal volume is reduced, the respiratory rate should be gradually increased to maintain the minute ventilation of the target object. Wherein, the minute ventilation is the product of the tidal volume and the respiratory rate, while the tidal volume is gradually reduced to the preset minimum level of 4 ml / kg at a gradient of 1 ml / kg, the respiratory rate increases in a trend opposite to the tidal volume. The respiratory rate can be adjusted to 35 times

[0042] / min at most.

[0043] S60, detecting whether the negative logarithm of the hydrogen ion concentration of the target object is in a preset concentration range, when it is detected that the negative logarithm of the hydrogen ion concentration is in the preset concentration range, maintaining the ventilator corresponding to the target object to operate in the target ventilation mode, and re-executing the pulse oximetry detection.

[0044] Understandably, the negative logarithm of the hydrogen ion concentration refers to the PH value. The preset concentration range refers to the limit range of the PH value.

[0045] Specifically, after determining that the platform pressure is less than or equal to the target platform pressure, whether the negative logarithm of the hydrogen ion concentration of the target object is in a preset concentration range is detected, that is, the negative logarithm of the hydrogen ion concentration of the target object is measured by the detection device, so as to obtain the negative logarithm of the hydrogen ion concentration of the target object. Then, the preset concentration range corresponding to the target object is obtained, and the negative logarithm of the hydrogen ion concentration and the preset concentration range are compared in size, so as to obtain a detection result representing whether the negative logarithm of the hydrogen ion concentration is in the preset concentration range. When it is detected that the negative logarithm of the hydrogen ion concentration is in the preset concentration range, the ventilator corresponding to the target object is maintained to operate in the target ventilation mode, and the detection process of pulse blood oxygen saturation detection, inhaled oxygen concentration detection, platform pressure detection and negative logarithm of hydrogen ion concentration detection on the target object is re-performed. When the negative logarithm of the hydrogen ion concentration exceeds the preset concentration range, a preset processing mode is adjusted, so that the negative logarithm of the hydrogen ion concentration is in the preset concentration range.

[0046] The embodiment of the present application realizes the control of the ventilator to operate in the target ventilation mode by inputting the mechanical ventilation parameters into the ventilator. By sequentially performing the pulse blood oxygen saturation detection, inhaled oxygen concentration detection, platform pressure detection and negative logarithm of hydrogen ion concentration detection on the target object, the detection of the next parameter when the previous result meets the requirement is realized, the adjustment of the parameter when the result does not meet the requirement is realized, and the maintenance of the ventilator to operate in the target ventilation mode is realized, thereby simplifying the mechanical ventilation management of the target object, solving the problem of complex mechanical ventilation management of the target object, and reducing the professional requirement of the operator.

[0047] In an embodiment, the blood oxygen detection result includes a first blood oxygen detection result for representing that the pulse blood oxygen saturation exceeds the preset blood oxygen range, and a second blood oxygen detection result for representing that the pulse blood oxygen saturation is in the preset blood oxygen range.

[0048] In the step S20, the pulse blood oxygen saturation detection on the target object applied to the ventilator operating in the target ventilation mode is performed to obtain a blood oxygen detection result, including:

[0049] S201, obtaining the pulse blood oxygen saturation of the target object.

[0050] S202, when the pulse blood oxygen saturation is less than a blood oxygen minimum threshold of the preset blood oxygen range, confirming that the blood oxygen detection result is a first blood oxygen detection result, and obtaining a second blood oxygen detection result after increasing the inhaled oxygen concentration until the pulse blood oxygen saturation is greater than or equal to the blood oxygen minimum threshold.

[0051] S203, when the pulse blood oxygen saturation is greater than the maximum threshold of the preset blood oxygen range, confirming that the blood oxygen detection result is a first blood oxygen detection result, and obtaining a second blood oxygen detection result after reducing the inhaled oxygen concentration until the pulse blood oxygen saturation is less than or equal to the maximum threshold of the blood oxygen range.

[0052] S204, when the pulse blood oxygen saturation is greater than or equal to the minimum threshold of the blood oxygen range and less than or equal to the maximum threshold of the blood oxygen range, obtaining a second blood oxygen detection result.

[0053] It can be understood that the pulse blood oxygen saturation, i.e. SPO2, is used to reflect the ability of the human body to deliver oxygen to all parts of the body. The preset blood oxygen range refers to the saturation range set in advance, for example, 85% to 95%. The maximum threshold of blood oxygen refers to the maximum value in the preset blood oxygen range. The minimum threshold of blood oxygen refers to the minimum value in the preset blood oxygen range.

[0054] Specifically, the pulse blood oxygen saturation of the target object is obtained, and the pulse blood oxygen saturation is compared with the preset blood oxygen range. When the pulse blood oxygen saturation is less than the minimum threshold of the preset blood oxygen range, a first blood oxygen detection result is obtained to represent that the pulse blood oxygen saturation is out of the preset blood oxygen range. Then, the inhaled oxygen concentration is increased at a preset increasing frequency until the pulse blood oxygen saturation is greater than or equal to the minimum threshold of the blood oxygen range, so as to obtain a second blood oxygen detection result representing that the pulse blood oxygen saturation is within the preset blood oxygen range. Further, when the pulse blood oxygen saturation is greater than the maximum threshold of the preset blood oxygen range, a first blood oxygen detection result is obtained to represent that the pulse blood oxygen saturation is out of the preset blood oxygen range. Then, the inhaled oxygen concentration is reduced at a preset decreasing frequency until the pulse blood oxygen saturation is less than or equal to the maximum threshold of the blood oxygen range, so as to obtain a second blood oxygen detection result representing that the pulse blood oxygen saturation is within the preset blood oxygen range. When the pulse blood oxygen saturation is greater than or equal to the minimum threshold of the blood oxygen range and less than or equal to the maximum threshold of the blood oxygen range, it is confirmed that the pulse blood oxygen saturation is within the preset blood oxygen range, so as to obtain a second blood oxygen detection result. That is, in the embodiment, by detecting and comparing the pulse blood oxygen saturation of the target object, when the pulse blood oxygen saturation is out of the preset blood oxygen range, the inhaled oxygen concentration is adjusted to make the pulse blood oxygen saturation within the preset blood oxygen range, thereby achieving the acquisition of the second blood oxygen detection result and the oxygenation management of the target object.

[0055] In an embodiment, the concentration detection result includes a first detection result representing that the inhaled oxygen concentration is greater than a preset inhaled oxygen threshold, and a second detection result representing that the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold.

[0056] In the step S30, the inhaled oxygen concentration of the target object is detected to obtain a concentration detection result, which includes:

[0057] S301, obtain the inhaled oxygen concentration of the target object, and compare the inhaled oxygen concentration of the target object with a preset inhaled oxygen threshold value.

[0058] S302, when the inhaled oxygen concentration is greater than the preset inhaled oxygen threshold value, a first detection result is obtained.

[0059] S303, when the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value, a second detection result is obtained.

[0060] It can be understood that the inhaled oxygen concentration, i.e. FIO2, refers to the concentration of inhaled oxygen of the target object. The preset inhaled oxygen threshold value refers to a limit value of the inhaled oxygen concentration of the target object set in advance. The concentration detection result includes a first detection result for representing that the inhaled oxygen concentration is greater than the preset inhaled oxygen threshold value, and a second detection result for representing that the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value.

[0061] Specifically, the inhaled oxygen concentration of the target object is obtained from a ventilator. Then, the inhaled oxygen concentration of the target object is compared with the preset inhaled oxygen threshold value, when the inhaled oxygen concentration is greater than the preset inhaled oxygen threshold value, a first detection result for representing that the inhaled oxygen concentration is greater than the preset inhaled oxygen threshold value is obtained. When the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value, a second detection result for representing that the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value is obtained. That is, in the embodiment, by comparing the inhaled oxygen concentration with the preset inhaled oxygen threshold value, the detection of the inhaled oxygen concentration of the target object is realized, and the acquisition of the first detection result or the second detection result is realized.

[0062] In an embodiment, after the method detects the inhaled oxygen concentration of the target object to obtain the concentration detection result, before detecting the plateau pressure of the target object to obtain the plateau pressure detection result, the method further comprises:

[0063] S70, when the concentration detection result represents that the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, obtaining chest parameter information of the target object, and detecting whether the chest parameter information meets preset parameter information.

[0064] S80, when the chest parameter information does not meet the preset parameter information, detecting and processing the ICP parameter of the target object to obtain a parameter detection result.

[0065] S90, when the parameter detection result represents that the ICP parameter is greater than a preset ICP threshold value, increasing the inhaled oxygen concentration of the target object.

[0066] The chest parameter information refers to the measurement of the chest of the target object, such as respiratory sound, presence of gas in the pleural cavity, presence of blood in the pleural cavity, etc. The preset parameter information refers to the information parameter set in advance, such as weakened respiratory sound, presence of gas in the pleural cavity, presence of blood in the pleural cavity, etc. The parameter detection result refers to the size between the ICP parameter and the preset ICP threshold value.

[0067] Specifically, after obtaining the concentration detection result, when the concentration detection result indicates that the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, the chest parameter of the target object is measured to obtain the chest parameter information of the target object. The chest parameter information is analyzed to determine whether the chest parameter information meets the preset parameter information. When the chest parameter information meets the preset parameter information, the plateau pressure of the target object is detected after the inhaled oxygen concentration is increased by the preset time length. Further, when the chest parameter information does not meet the preset parameter information, the ICP parameter of the target object is measured to obtain the ICP parameter, and then the size between the ICP parameter of the target object and the preset ICP threshold value is compared to obtain the parameter detection result. When the parameter detection result indicates that the ICP parameter is greater than the preset ICP threshold value, the inhaled oxygen concentration of the target object is increased at the preset increasing frequency.

[0068] In a specific embodiment, when the concentration detection result indicates that the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, the respiratory sound of the target object is detected, and it is determined whether the respiratory sound is weakened. When the respiratory sound is not weakened, it is observed whether the chest of the target object is sunken during inhalation and protruded during exhalation. If not, the ICP parameter is detected. When the respiratory sound is weakened, it is detected whether the arterial blood carbon dioxide partial pressure of the target object is less than the preset partial pressure. When the arterial blood carbon dioxide partial pressure is greater than or equal to the preset partial pressure, it is detected whether there is gas in the pleural cavity or whether there is blood in the pleural cavity. If not, the inhaled oxygen concentration is increased. When the arterial blood carbon dioxide partial pressure is less than the preset partial pressure, or when there is blood in the pleural cavity, a tube is placed in the thoracic cavity to discharge the gas or blood.

[0069] In this embodiment, by detecting whether the chest parameter information meets the preset parameter information, the detection of the chest parameter information is realized, the detection of the ICP parameter of the target object is realized, and the adjustment of the inhaled oxygen concentration when the ICP parameter is greater than the preset ICP threshold value is realized.

[0070] In an embodiment, after the step S80, i.e., after the detection of the ICP parameter of the target object to obtain the parameter detection result, the method further comprises:

[0071] S100, when the parameter detection result indicates that the ICP parameter is less than or equal to the preset ICP threshold value, detecting whether the lung information parameter of the target object is abnormal.

[0072] S110, when it is detected that the lung information parameter is not abnormal, increasing the positive end-expiratory pressure at a preset adjustment frequency, and re-performing the pulse blood oxygen saturation detection.

[0073] S120, when it is detected that the lung information parameter is abnormal, issuing an alarm to prompt adjustment of the mechanical ventilation strategy corresponding to the target object.

[0074] It can be understood that the lung information parameter refers to the result of measuring the lung of the target object.

[0075] Specifically, after obtaining the parameter detection result, when the parameter detection result represents that the ICP parameter is less than or equal to the preset ICP threshold, the lung information of the target object is measured to obtain the lung information parameter of the target object. Then, the lung information parameter is compared with the preset lung parameter to determine whether the lung information parameter of the target object is abnormal. Further, when it is detected that the lung information parameter is not abnormal, the positive end-expiratory pressure is increased at a preset adjustment frequency, and the pulse blood oxygen saturation of the target object is re-detected. When it is detected that the lung information parameter is abnormal, an alarm is issued to prompt the operator to adjust the mechanical ventilation strategy corresponding to the target object. That is, in the embodiment, by detecting whether the lung information parameter of the target object is abnormal, the positive end-expiratory pressure is increased at a preset adjustment frequency when it is not abnormal, and an alarm is issued to prompt adjustment of the mechanical ventilation strategy when it is abnormal.

[0076] In an embodiment, the plateau pressure detection result includes a first plateau pressure detection result for representing that the plateau pressure is less than or equal to the target plateau pressure, and a second plateau pressure detection result for representing that the plateau pressure is greater than the target plateau pressure.

[0077] In the step S40, the plateau pressure of the target object is detected to obtain a plateau pressure detection result, including:

[0078] S401, obtaining the plateau pressure of the target object and the target plateau pressure corresponding to the target object.

[0079] S402, comparing the target plateau pressure and the plateau pressure corresponding to the same target object.

[0080] S403, obtaining a first plateau pressure detection result when the plateau pressure is less than or equal to the target plateau pressure.

[0081] S404, obtaining a second plateau pressure detection result when the plateau pressure is greater than the target plateau pressure.

[0082] Understandably, the platform pressure, Pplat, refers to the pressure maintained in the airway from the end of inspiration to the beginning of expiration. The target platform pressure refers to the maximum platform pressure corresponding to the target object.

[0083] Specifically, the platform pressure of the target object is obtained, and the target platform pressure corresponding to the target object is obtained, and the target platform pressure and the platform pressure corresponding to the same target object are compared. When the platform pressure is less than or equal to the target platform pressure, a first platform pressure detection result for representing that the platform pressure is less than or equal to the target platform pressure is obtained. When the platform pressure is greater than the target platform pressure, a second platform pressure detection result for representing that the platform pressure is greater than the target platform pressure is obtained. That is, in the embodiment, by measuring the platform pressure of the target object and comparing the size of the target platform pressure and the platform pressure, the detection of the platform pressure of the target object is realized, and the acquisition of the first platform pressure detection result or the second platform pressure detection result is realized.

[0084] In an embodiment, the step S60, that is, whether the negative logarithm of the hydrogen ion concentration of the target object is in the preset concentration range, comprises:

[0085] S601, obtaining the negative logarithm of the hydrogen ion concentration of the target object.

[0086] S602, when the negative logarithm of the hydrogen ion concentration is greater than the maximum concentration of the preset concentration range, it is determined that the negative logarithm of the hydrogen ion concentration is out of the preset concentration range, and the respiratory rate is reduced until the negative logarithm of the hydrogen ion concentration is less than or equal to the maximum concentration, and then it is determined that the negative logarithm of the hydrogen ion concentration is in the preset concentration range.

[0087] S603, when the negative logarithm of the hydrogen ion concentration is less than the minimum concentration of the preset concentration range, it is determined that the negative logarithm of the hydrogen ion concentration is out of the preset concentration range, and the platform pressure of the target object is obtained, and the negative logarithm of the hydrogen ion concentration is adjusted to be greater than or equal to the minimum concentration after the platform pressure and the preset platform pressure threshold value are compared, and then it is determined that the negative logarithm is in the preset concentration range; wherein, when the platform pressure of the target object is less than the preset platform pressure threshold value, the negative logarithm of the hydrogen ion concentration is greater than or equal to the minimum concentration by increasing the tidal volume and the respiratory rate; when the platform pressure of the target object is greater than or equal to the preset platform pressure threshold value, the negative logarithm of the hydrogen ion concentration is greater than or equal to the minimum concentration by increasing the respiratory rate.

[0088] S604, when the negative logarithm of the hydrogen ion concentration is greater than or equal to the minimum concentration and less than or equal to the maximum concentration, it is determined that the negative logarithm of the hydrogen ion concentration is in the preset concentration range.

[0089] It is understandable that the negative logarithm of the hydrogen ion concentration, ie, pH, is used to characterize the pH value of the target object. The preset plateau pressure threshold refers to a limit value of the plateau pressure set when the pH value is not within a preset range.

[0090] Specifically, the negative logarithm of the hydrogen ion concentration of the target subject is obtained and compared with the minimum and maximum concentrations within a preset concentration range. When the negative logarithm of the hydrogen ion concentration is greater than the maximum concentration within the preset concentration range, the negative logarithm of the hydrogen ion concentration is determined to be outside the preset concentration range. The respiratory rate is reduced to reduce the negative logarithm of the hydrogen ion concentration to less than or equal to the maximum concentration, and the negative logarithm of the hydrogen ion concentration is determined to be within the preset concentration range. Furthermore, when the negative logarithm of the hydrogen ion concentration is less than the minimum concentration within the preset concentration range, the negative logarithm of the hydrogen ion concentration is determined to be outside the preset concentration range. The plateau pressure of the target subject is then obtained, and the negative logarithm of the hydrogen ion concentration is adjusted based on the plateau pressure and a preset plateau pressure threshold to adjust the negative logarithm of the hydrogen ion concentration to greater than or equal to the minimum concentration, and the negative logarithm is determined to be within the preset concentration range. When the plateau pressure of the target subject is less than the preset plateau pressure threshold, the tidal volume and respiratory rate are increased at a preset frequency to increase the negative logarithm of the hydrogen ion concentration to greater than or equal to the minimum concentration. Next, when the target subject's plateau pressure is greater than or equal to a preset plateau pressure threshold, the respiratory rate is increased at a preset rate so that the negative logarithm of the hydrogen ion concentration is greater than or equal to the minimum concentration value. That is, in this embodiment, by comparing the negative logarithm of the target subject's hydrogen ion concentration with a preset concentration range, the respiratory rate is adjusted when the preset concentration range is exceeded. When the negative logarithm of the hydrogen ion concentration is less than the minimum concentration value of the preset concentration range, the plateau pressure is compared to determine the adjustment method to ensure that the negative logarithm of the hydrogen ion concentration is within the preset concentration range.
