[0003] In the prior art, an increase in intracranial pressure (ICP, Intracranial Pressure) can cause brain tissue hypoxia. Therefore, it is crucial to control the mechanical ventilation of traumatic brain injury (TBI, Traumatic Brain Injury) patients. However, controlling the mechanical ventilation of traumatic brain injury patients requires manual detection and control by professionals, which is a large workload and requires high professional requirements for the operator. In addition, the mechanical ventilation operation of the respirator is difficult to accurately control, resulting in complex TBI mechanical ventilation management. SUMMARY

[0024] Figure 2 This is a schematic diagram of a ventilator ventilation management device based on TBI in one embodiment of the present invention. Detailed Implementation

[0025] 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.

[0026] This invention provides a ventilator ventilation management method based on TBI. In one embodiment, as follows: Figure 1 As shown, its technical solution mainly includes the following steps:

[0027] S10, perform abnormal detection on the lung parameter information of the target object, and when there is no abnormality in the lung parameter information of the target object, control the ventilator to operate in the first ventilation mode with the first preset parameters.

[0028] The ventilator is a device that can replace, control or change the normal physiological respiration of a person. The first preset parameter refers to the operation parameter of the ventilator with the lung parameter information set in advance. The first ventilation mode refers to the ventilation mode corresponding to the first preset parameter, such as VCV (volume control ventilation mode) or PCV (pressure control ventilation mode). The lung parameter information refers to the collected value of the lung condition of the target object. The target object refers to a person with traumatic brain injury who needs mechanical ventilation management.

[0029] Specifically, the lung parameter information of the target object is obtained, which can be input to the ventilator by the client or collected by other devices connected to the ventilator and transmitted to the ventilator. The lung parameter information of the target object is compared with the normal parameter information. When the lung parameter information of the target object is normal, it is determined that the lung parameter information of the target object is normal. When the lung parameter information of the target object is not normal, it is determined that the lung parameter information of the target object is abnormal. Then, when the lung parameter information of the target object is normal, the first preset parameter is obtained from the database and input to the ventilator, and the ventilator is controlled to run in the first ventilation mode of the second preset parameter. In an embodiment, the ventilation parameter is set to CMV (A / C), PCV or VCV, the tidal volume is 6-8 ml / kg IBM, the inspired oxygen concentration is 100%, the respiratory rate is 15 / min, the inspiration time is 1 s, and the positive end-expiratory pressure is 5 cmH20. The ventilation parameter is set to VCV by default, the tidal volume is 6 ml / kg IBM, the inspired oxygen concentration is 100%, the respiratory rate is 15 / min, the inspiration time is 1 s, and the positive end-expiratory pressure is 5 cmH20. For example, VCV (volume control ventilation mode) or PCV (pressure control ventilation mode).

[0030] S20, oxygenation management is performed on the target object corresponding to the ventilator running in the first ventilation mode, so that the blood oxygen saturation is greater than or equal to a blood oxygen saturation threshold.

[0031] The blood oxygen saturation refers to the percentage of oxygen in the blood combined with hemoglobin, which is used to represent the content of oxygen in the blood, i.e. SpO2. The blood oxygen saturation threshold refers to a limit value for judging the blood oxygen saturation level of the target object, for example, 92%.

[0032] Specifically, after the target object is mechanically ventilated, the blood oxygen saturation of the target object is obtained, i.e., blood gas analysis is performed on the target object by transcutaneous measurement, so as to obtain the blood oxygen saturation. Then, the target object corresponding to the ventilator running in the first ventilation mode is oxygenation managed by the blood oxygen saturation, i.e., the blood oxygen saturation of the target object is compared with the blood oxygen saturation threshold, and when the blood oxygen saturation is less than the blood oxygen saturation threshold, the inhaled oxygen concentration is adjusted, so that the blood oxygen saturation is greater than or equal to the blood oxygen saturation threshold, to achieve oxygenation management.

[0033] S30, compare the ICP parameter of the target object with the preset ICP threshold value, and when the ICP parameter of the target object is greater than the preset ICP threshold value, perform parameter management on the arterial blood carbon dioxide partial pressure of the target object to obtain a parameter management result.

[0034] Understandably, the parameter management result is used to represent whether the arterial blood carbon dioxide partial pressure is within the preset parameter range. The ICP parameter refers to a value used to represent the intracranial pressure of the target object. The preset ICP threshold value refers to a limit value used to evaluate the intracranial pressure level of the target object, for example, 20 mmHg. The arterial blood carbon dioxide partial pressure refers to the tension or pressure generated by the carbon dioxide molecules dissolved in the arterial blood, i.e., PCO2.

[0035] Specifically, the ICP parameter of the target object is obtained, and the preset ICP threshold value set in advance is obtained, and the ICP parameter of the target object and the preset ICP threshold value are compared in size. Then, when the ICP parameter of the target object is greater than the preset ICP threshold value, the arterial blood carbon dioxide partial pressure of the target object is obtained, and the arterial blood carbon dioxide partial pressure of the target object and the preset parameter range are compared in size, so as to obtain the parameter management result.

[0036] S40, when the parameter management result represents that the arterial blood carbon dioxide partial pressure is within the preset parameter range, performing parameter detection on the blood oxygen partial pressure and the inhaled oxygen concentration of the target object to obtain a parameter detection result.

[0037] Understandably, the parameter detection result is used to represent whether the blood oxygen partial pressure is within the preset detection range and whether the inhaled oxygen concentration is less than the preset inhaled oxygen threshold value. The preset parameter range refers to the normal range of the arterial blood carbon dioxide partial pressure, i.e., 35 mmHg to 45 mmHg. The inhaled oxygen concentration refers to the concentration of inhaled oxygen, i.e., FIO2.

[0038] Specifically, when the parameter management result indicates that the arterial blood carbon dioxide partial pressure is within the preset parameter range, the blood oxygen partial pressure of the target object is obtained, and the blood oxygen partial pressure of the target object is compared with the preset detection range. Then, when the blood oxygen partial pressure is within the preset detection range, the inhaled oxygen concentration of the target object is obtained, and the inhaled oxygen concentration of the target object is compared with the preset inhaled oxygen threshold value, so as to obtain a parameter detection result.

[0039] S50, when the parameter detection result indicates that the blood oxygen partial pressure is within the preset detection range and the inhaled oxygen concentration is less than the preset inhaled oxygen threshold value, whether the ICP parameter of the target object is abnormal is detected.

[0040] Understandably, the preset inhaled oxygen threshold value refers to a limit value of inhaled oxygen concentration preset to ensure that the target object obtains sufficient oxygen. The preset detection range refers to the normal range of blood oxygen partial pressure.

[0041] Specifically, when the parameter detection result indicates that the blood oxygen partial pressure is within the preset detection range and the inhaled oxygen concentration is less than the preset inhaled oxygen threshold value, the ICP parameter of the target object is obtained, and the ICP parameter of the target object is compared with the preset ICP threshold value, so as to determine whether the ICP parameter of the target object is abnormal. When the ICP parameter is less than the preset ICP threshold value, it is determined that the ICP parameter is normal. When the ICP parameter is greater than or equal to the preset ICP threshold value, it is determined that the ICP parameter is abnormal.

[0042] S60, when the ICP parameter is normal, the target object is given a GCS score to obtain a score result. When the score result is greater than a score threshold value, a tube extraction operation is performed to confirm the end of the ventilation management of the target object.

[0043] Understandably, the score result refers to the numerical value of the GCS score of the target object. The score threshold value refers to a limit value for evaluating whether the target object can be extubated.

[0044] Specifically, when the ICP parameter is normal, the target object is given a GCS score, that is, the target object is given a first reaction score by a first preset operation instruction, a second reaction score by a second preset operation instruction, and a third reaction score by a third preset operation instruction. The sum of all score values is obtained to obtain a score result. Then, a preset score threshold value is obtained, and the score result is compared with the score threshold value. When the score result is greater than the score threshold value, an operation is performed according to a preset scheme. When the score result is greater than the score threshold value, a tube extraction operation is performed to confirm the end of the ventilation management of the target object.

[0045] The embodiment of the present application realizes the acquisition of the first preset parameter when the lung parameter information of the target object is normal, and realizes the operation of the ventilator in the first ventilation mode through the abnormal detection of the lung parameter information of the target object. Through the oxygenation management, ICP parameter comparison, arterial blood carbon dioxide partial pressure parameter management, blood oxygen partial pressure parameter detection, inhaled oxygen concentration parameter detection and GCS score detection of the target object in turn, the detection of the next parameter when the previous result meets the condition is realized, thereby improving the precision and accuracy of the ventilation control of the ventilator, simplifying the complex process of parameter detection, and realizing the precise control of the mechanical ventilation of the target object.

[0046] In an embodiment, the step S10, i.e., the abnormal detection of the lung parameter information of the target object, further includes:

[0047] When the lung parameter information of the target object is abnormal, the ventilator is controlled to operate in the second ventilation mode with the second preset parameter.

[0048] Understandably, the second preset parameter refers to the operation parameter of the ventilator when the lung parameter information is abnormal. The second ventilation mode refers to the ventilation mode corresponding to the second preset parameter, for example, VCV (i.e., volume control ventilation mode) or PCV (i.e., pressure control ventilation mode).

[0049] Specifically, the lung parameter information of the target object is acquired, and the lung parameter information of the target object is compared with the normal parameter information. When the lung parameter information of the target object is normal, it is determined that the lung parameter information of the target object is normal. When the lung parameter information of the target object is not normal, it is determined that the lung parameter information of the target object is abnormal. Then, the second preset parameter is acquired from the database and input into the ventilator, and the ventilator is controlled to operate in the second ventilation mode with the second preset parameter. In an embodiment, the second preset parameter is set to the auxiliary ventilation A / C mode, PCV or VCV, the tidal volume is 4-8 ml / kg IBM, FiO2 is 100%, the respiratory rate is 20 / min, the inspiration time is 1 s, and the positive end-expiratory pressure is 5 cmH20, by default, VCV, the tidal volume is 4 ml / kg IBM, the inhaled oxygen concentration is 100%, the respiratory rate is 20 / min, the inspiration time is 1 s, and the positive end-expiratory pressure is 5 cmH20. The operation of steps S20 to S60 is also required when operating in the second ventilation mode, which will not be repeated here. That is, in the embodiment, when the lung parameter information of the target object is abnormal, the ventilator is controlled to operate in the second ventilation mode with the second preset parameter.

[0050] In an embodiment, after the step S30 and before the step S40, i.e. after comparing the ICP parameter of the target object with the preset ICP threshold value and before performing parameter detection on the partial pressure of oxygen and the inhaled oxygen concentration of the target object, the method further comprises the following steps:

[0051] S301, when the ICP parameter is less than or equal to the preset ICP threshold value, comparing the CVP parameter with the ICP parameter.

[0052] S302, when the CVP parameter is less than the ICP parameter, comparing the inhaled oxygen concentration with a preset inhaled oxygen threshold value.

[0053] S303, when the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value, increasing the positive end-expiratory pressure so that the oxygen saturation is greater than or equal to an oxygen saturation threshold value, and performing parameter management.

[0054] S304, when the CVP parameter is greater than or equal to the ICP parameter, performing parameter management on the arterial carbon dioxide partial pressure of the target object to obtain a parameter management result.

[0055] It can be understood that the CVP is Central Venous Pressure. The CVP parameter refers to the size of the central venous pressure.

[0056] Specifically, after comparing the ICP parameter of the target object with the preset ICP threshold value and before performing parameter detection on the partial pressure of oxygen and the inhaled oxygen concentration of the target object, when the ICP parameter is less than or equal to the preset ICP threshold value, the CVP parameter of the target object is obtained, and the CVP parameter of the target object is compared with the ICP parameter. When the CVP parameter is greater than or equal to the ICP parameter, the arterial carbon dioxide partial pressure of the target object is managed to obtain a parameter management result. Further, when the CVP parameter is less than the ICP parameter, the inhaled oxygen concentration of the target object is obtained, and the preset inhaled oxygen threshold value is called from the database, and the inhaled oxygen concentration and the preset inhaled oxygen threshold value are compared. When the inhaled oxygen concentration is greater than the preset inhaled oxygen threshold value, the ventilator is maintained to run in the first ventilation mode, and the GCS score of the target object is performed. When the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value, the positive end-expiratory pressure is increased so that the oxygen saturation is greater than or equal to the oxygen saturation threshold value, and the inhaled oxygen concentration is less than or equal to the preset inhaled oxygen threshold value, and the arterial carbon dioxide partial pressure of the target object is managed. If the inhaled oxygen concentration is greater than the preset inhaled oxygen threshold value after adjusting the positive end-expiratory pressure, the ventilator is maintained to run in the first ventilation mode, and the GCS score of the target object is performed to obtain a score result.

[0057] In this embodiment, by detecting the ICP parameter, the accurate control of mechanical ventilation of the target object is realized, and the judgment of the CVP parameter and the ICP parameter is realized. When the CVP parameter is less than the ICP parameter, the adjustment of the parameter is realized, and then the parameter management of the arterial blood carbon dioxide partial pressure of the target object is realized, and the acquisition of the parameter management result is realized.

[0058] In an embodiment, the step S30, that is, the parameter management of the arterial blood carbon dioxide partial pressure of the target object, obtains a parameter management result, and a preset parameter range includes a first parameter threshold and a second parameter threshold; the first parameter threshold is greater than the second parameter threshold; and the step S30 includes:

[0059] S305, comparing the arterial blood carbon dioxide partial pressure of the target object with the first parameter threshold and the second parameter threshold respectively, and obtaining a parameter comparison result.

[0060] S306, when the parameter comparison result represents that the arterial blood carbon dioxide partial pressure is greater than the first parameter threshold, increasing the respiratory frequency so that the arterial blood carbon dioxide partial pressure is less than or equal to the first parameter threshold.

[0061] S307, when the parameter comparison result represents that the arterial blood carbon dioxide partial pressure is less than the second parameter threshold, comparing the airway plateau pressure of the target object with a preset plateau pressure threshold.

[0062] S308, when the airway plateau pressure of the target object is greater than the preset plateau pressure threshold, reducing the tidal volume so that the arterial blood carbon dioxide partial pressure is less than or equal to the second parameter threshold.

[0063] S309, when the airway plateau pressure of the target object is less than or equal to the preset plateau pressure threshold, reducing the respiratory frequency so that the arterial blood carbon dioxide partial pressure is less than or equal to the second parameter threshold.

[0064] S310, when the parameter comparison result represents that the arterial blood carbon dioxide partial pressure is greater than or equal to the first parameter threshold and less than or equal to the second parameter threshold, obtaining a parameter management result representing that the arterial blood carbon dioxide partial pressure is in the preset parameter range.

[0065] The arterial blood carbon dioxide partial pressure is the pressure or tension generated by the carbon dioxide molecules dissolved in the arterial blood, denoted as PaCO2. The preset parameter range refers to the range of the arterial blood carbon dioxide partial pressure set in advance, including a first parameter threshold and a second parameter threshold, and the first parameter threshold is greater than the second parameter threshold. The parameter comparison result is used to represent the size of the arterial blood carbon dioxide partial pressure and the threshold value. The respiratory frequency refers to the number of breaths per minute. The airway plateau pressure refers to the pressure in the airway from the end of inspiration to the beginning of expiration. The preset plateau pressure threshold refers to the threshold of the airway plateau pressure set in advance.

[0066] Specifically, the first parameter threshold and the second parameter threshold included in the preset parameter range are retrieved from the database, and then the arterial blood carbon dioxide partial pressure of the target object is compared with the first parameter threshold and the second parameter threshold respectively to obtain the parameter comparison result. When the parameter comparison result represents that the arterial blood carbon dioxide partial pressure is greater than the first parameter threshold, the respiratory frequency is increased so that the arterial blood carbon dioxide partial pressure is less than or equal to the first parameter threshold. When the parameter comparison result represents that the arterial blood carbon dioxide partial pressure is less than the second parameter threshold, the airway plateau pressure of the target object is obtained and compared with the preset plateau pressure threshold. When the airway plateau pressure of the target object is greater than the preset plateau pressure threshold, the tidal volume is reduced so that the arterial blood carbon dioxide partial pressure is less than or equal to the second parameter threshold. When the airway plateau pressure of the target object is less than or equal to the preset plateau pressure threshold, the respiratory frequency is reduced so that the arterial blood carbon dioxide partial pressure is less than or equal to the second parameter threshold. Then, when the parameter comparison result represents that the arterial blood carbon dioxide partial pressure is greater than or equal to the first parameter threshold and less than or equal to the second parameter threshold, the parameter management result representing that the arterial blood carbon dioxide partial pressure is within the preset parameter range is obtained.

[0067] In this embodiment, by comparing the arterial blood carbon dioxide partial pressure of the target object with the first parameter threshold and the second parameter threshold, the acquisition of the parameter comparison result is realized. When the parameter comparison result represents different contents, the adjustment of the respiratory frequency and the tidal volume is realized, and then the acquisition of the parameter management result is realized.

[0068] In an embodiment, the step S40, i.e., the parameter detection of the blood oxygen partial pressure and the inhaled oxygen concentration of the target object, obtains a parameter detection result, including:

[0069] S401, compare the blood oxygen partial pressure of the target object with the preset detection range; the preset detection range includes a first detection threshold and a second detection threshold; the first detection threshold is greater than the second detection threshold.

[0070] S402, when the blood oxygen partial pressure is greater than the first detection threshold, reducing the inhaled oxygen concentration so that the blood oxygen partial pressure is less than or equal to the first detection threshold.

[0071] S403, when the blood oxygen partial pressure is less than the second detection threshold, comparing the inhaled oxygen concentration with a preset inhaled oxygen threshold, and when the inhaled oxygen concentration is less than the preset inhaled oxygen threshold, increasing the inhaled oxygen concentration so that the blood oxygen partial pressure is within the preset detection range.

[0072] S404, when the blood oxygen partial pressure is less than or equal to the first detection threshold and greater than or equal to the second detection threshold, comparing the inhaled oxygen concentration with the preset inhaled oxygen threshold.

[0073] S405, when the inhaled oxygen concentration is less than the preset inhaled oxygen threshold, obtaining a parameter detection result representing that the blood oxygen partial pressure is within the preset detection range and the inhaled oxygen concentration is less than the preset inhaled oxygen threshold.

[0074] It can be understood that the first detection threshold and the second detection threshold refer to the interval values of the preset detection range. The first detection threshold is greater than the second detection threshold.

[0075] Specifically, after obtaining the parameter management result, the blood oxygen partial pressure of the monitored target object is obtained, and the preset detection range corresponding to the blood oxygen partial pressure is called from the database, and the blood oxygen partial pressure of the target object and the preset detection range are compared. Then, when the blood oxygen partial pressure is greater than the first detection threshold, the inhaled oxygen concentration of the target object is reduced so that the blood oxygen partial pressure is less than or equal to the first detection threshold. When the blood oxygen partial pressure is less than the second detection threshold, the inhaled oxygen concentration of the target object is obtained, and the inhaled oxygen concentration and the preset inhaled oxygen threshold are compared, and when the inhaled oxygen concentration is less than the preset inhaled oxygen threshold, the inhaled oxygen concentration is increased so that the blood oxygen partial pressure is within the preset detection range. Further, when the blood oxygen partial pressure is less than or equal to the first detection threshold and greater than or equal to the second detection threshold, i.e. the blood oxygen partial pressure of the target object is within the preset detection range, then the inhaled oxygen concentration of the target object is obtained, and the preset inhaled oxygen threshold is called from the database, and the inhaled oxygen concentration and the preset inhaled oxygen threshold are compared. When the inhaled oxygen concentration is less than the preset inhaled oxygen threshold, a parameter detection result representing that the blood oxygen partial pressure is within the preset detection range and the inhaled oxygen concentration is less than the preset inhaled oxygen threshold is obtained. When the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold, refer to subsequent steps S406 and S407, which will not be described one by one.

[0076] In the embodiment, the judgment of whether the partial pressure of blood oxygen is in the preset detection range is realized, and then the adjustment of the partial pressure of blood oxygen when it is not in the preset detection range is realized. The detection of the inhaled oxygen concentration is realized, and then the adjustment of the inhaled oxygen concentration when it is greater than or equal to the preset inhaled oxygen threshold value is realized. Further, the acquisition of the parameter detection result is realized.

[0077] In an embodiment, after the step S403, that is, after the comparison of the inhaled oxygen concentration and the preset inhaled oxygen threshold value, the method further comprises:

[0078] S406, when the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, comparing the ICP parameter of the target object and the preset ICP threshold value, and when the ICP parameter is greater than or equal to the preset ICP threshold value, increasing the inhaled oxygen concentration so that the partial pressure of blood oxygen is in the preset detection range.

[0079] S407, when the ICP parameter is less than the preset ICP threshold value, increasing the positive end-expiratory pressure so that the partial pressure of blood oxygen is in the preset detection range.

[0080] Specifically, after the comparison of the inhaled oxygen concentration and the preset inhaled oxygen threshold value, when the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, the ICP parameter of the target object is acquired, and the preset ICP threshold value is called from the database, and then the ICP parameter of the target object and the preset ICP threshold value are compared, when the ICP parameter is greater than or equal to the preset ICP threshold value, the inhaled oxygen concentration is increased so that the partial pressure of blood oxygen is in the preset detection range. When the ICP parameter is less than the preset ICP threshold value, the positive end-expiratory pressure is increased so that the partial pressure of blood oxygen is in the preset detection range.

[0081] In the embodiment, by comparing the ICP parameter of the target object and the preset ICP threshold value when the inhaled oxygen concentration is greater than or equal to the preset inhaled oxygen threshold value, the judgment of the ICP parameter is realized, and then the adjustment of the ICP parameter under different conditions is realized, so that the partial pressure of blood oxygen is ensured to be in the preset detection range.

[0082] In an embodiment, in the step S60, that is, after the GCS score of the target object is obtained,

[0083] the score result is obtained, comprising:

[0084] S601, the eye opening reaction score of the target object is obtained, and the first score result is obtained.

[0085] It can be understood that the first score result is the score value of the eye opening reaction.

[0086] Specifically, after the ICP parameters are normal, the mechanical ventilation management settings of the ventilator are maintained, then the first preset operation instruction is used to score the eye opening response of the target object, that is, it is observed whether the target object can open eyes independently, that is, a face image can be taken for analysis and judgment. If not, the target object is informed to open eyes, and the face information of the target object is taken to obtain a face image, and the eye region in the face image is analyzed to determine whether the eyes are open. If not, after stimulating the target object, the face image is taken for analysis and judgment to determine whether the eyes are open after stimulation. When the eye region is abnormal, the result is determined by a preset scheme. Finally, the level of the target object meeting the eye opening response is determined, and the score value of the level meeting the eye opening response is determined as the first score result.

[0087] S602, score the language response of the target object to obtain a second score result.

[0088] Understandably, the second score result refers to the score value of the language response.

[0089] Specifically, the second preset operation instruction is used to score the language response of the target object, that is, a language instruction is issued, the sound is received by the audio device, and the received audio is matched with the preset level to determine whether the answer is completely correct. If not, it is detected whether the received audio is continuous. If not, it is detected whether the received audio contains the voice of the target object. If not, there is no response. In addition, the face image can be taken by the shooting device to analyze the characteristics of the lips of the target object to determine the level of the target object meeting the language response, and the score value corresponding to the level of the target object meeting the language response is determined as the second score result.

[0090] S603, score the limb response of the target object to obtain a third score result.

[0091] S604, determine the score result according to the first score result, the second score result and the third score result.

[0092] Understandably, the third score result refers to the score value of the limb response.

[0093] Specifically, the target object is scored for limb reaction through the third preset operation instruction, that is, limb movement instructions are issued, and the corresponding limbs of the target object are monitored by the monitoring device to determine whether the limbs move according to the limb movement instructions. If not, the target object is stimulated at a preset position, and it is monitored whether the target object can determine the stimulation position. If not, it is monitored whether the target object can retract the limbs. If not, it is monitored whether the target object can bend the limbs.
