In different embodiments, similar elements are denoted by similar reference numerals. In the following embodiments, many details are described in order to make the application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials or methods.

[0025] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments. Meanwhile, the steps or actions in the method description can also be adjusted or changed in sequence as long as they are obvious to those skilled in the art. Therefore, the sequence in the specification and the drawings is only for clear description of an embodiment and does not mean a necessary sequence, unless otherwise stated that a certain sequence must be followed.

[0026] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meaning. The "connection" and "coupling" in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0027] Please refer to Figure 1 The embodiment shown in FIG. 1 provides a medical device system, which includes a respiratory support device 10, a ventilation therapy auxiliary device 20, and a display device 30. The respiratory support device 10 is used to provide ventilation therapy for a patient, which refers to providing respiratory support for the patient in a mechanical ventilation manner. There are different ventilation strategies in the ventilation therapy, and accordingly, the respiratory support device 10 can be a ventilator, an anesthesia machine, an oxygen therapy instrument, etc. In this application, the ventilation strategy includes at least one of a ventilation mode and a ventilation manner. The ventilation mode can be changed while keeping the current ventilation manner, or the ventilation manner can be changed and the ventilation mode can also be changed. In this application, the ventilation manner includes but is not limited to conventional (low flow) oxygen therapy, high flow oxygen therapy, non-invasive ventilation, invasive ventilation, high frequency ventilation, and extracorporeal membrane oxygenation (ECMO), and the ventilation mode includes but is not limited to continuous positive airway pressure, volume control mode ventilation, pressure control mode ventilation, pressure support ventilation, bi-level positive airway pressure, bi-level positive airway pressure, airway pressure release ventilation, pressure-regulated volume control ventilation, volume support ventilation, synchronized intermittent mandatory ventilation, volume guarantee pressure support ventilation, and closed-loop ventilation. The above-mentioned ventilation manners and ventilation modes are all common in the art, and those skilled in the art can certainly determine the specific meanings of the ventilation manners and ventilation modes.

[0028] The ventilation therapy auxiliary device 20 at least includes a parameter acquisition device 21 and a processor 22.

[0029] The parameter acquisition device 21 is used to acquire physiological parameters and ventilation parameters of the patient during the ventilation therapy. The physiological parameters include but are not limited to blood oxygen saturation, heart rate, blood pressure, and end-tidal carbon dioxide, and the ventilation parameters include directly measurable or settable parameters such as oxygen concentration, inspired oxygen partial pressure, airway flow rate, airway pressure, tidal volume, and respiratory rate, and also include parameters obtained by certain calculations based on these parameters, such as minute ventilation (MV), etc. It should be noted that the classification of physiological parameters and ventilation parameters is only for more concise description of the technical solutions of this application, and should not be understood as a limitation on the classification of parameters in this application. In other embodiments, the parameters can also be classified in other ways. For example, the parameters involved in this application can be classified into blood oxygen pulse parameters and respiratory parameters. The blood oxygen pulse parameters include but are not limited to blood oxygen saturation, heart rate, and blood pressure, and the respiratory parameters include but are not limited to respiratory rate, end-tidal carbon dioxide, oxygen concentration, inspired oxygen partial pressure, airway flow rate, airway pressure, tidal volume, and minute ventilation, etc.

[0030] The parameter acquisition device 21 can include sensors 21a for acquiring physiological parameters and ventilation parameters in real time or at intervals. The sensors 21a can include multiple sensors, such as a pressure sensor for acquiring airway pressure and a flow sensor for acquiring airway flow rate. In some embodiments, the parameter acquisition device 21 includes a communication device 21b for receiving physiological parameters and ventilation parameters, that is, the ventilation therapy assistance device 20 does not acquire data by itself. For example, the respiratory support device 10 can send physiological parameters and ventilation parameters acquired by itself to the communication device 21b in real time or at intervals, and if some ventilation parameters are set by a user, the respiratory support device 10 can directly send the parameter values of the set ventilation parameters to the communication device 21b. For example, the respiratory support device 10 is a ventilator, and the user can set the oxygen concentration during the ventilation therapy, and the ventilator can send the value of the set oxygen concentration to the communication device 21b for subsequent processing by the ventilation therapy assistance device 20. In another embodiment, the parameter acquisition device 21 can include both the sensors 21a and the communication device 21b, that is, the ventilation therapy assistance device 20 can acquire part of the parameters by itself and receive parameters sent by other medical devices. For example, the blood oxygen saturation can be obtained from blood gas measurement, transcutaneous measurement, or pulse oximetry measurement.

[0031] The processor 22 is configured to start timing when it is detected that the timing condition is met, and obtain the ventilation therapy time according to the timing. The timing condition can be the start of ventilation therapy, for example, starting timing when it is detected that the respiratory support device 10 starts working; or receiving a timing start instruction input by a user; or the physiological parameters and ventilation parameters of the patient meeting a precondition. For example, in nasal high-flow oxygen therapy (HFNC), the precondition can be set as PaO2 / FiO2(or SpO2 / FiO2) > 150 mmHg. Wherein, PaO2 is the arterial oxygen partial pressure, FiO2 is the inhaled oxygen partial pressure, and SpO2 is the blood oxygen saturation. In some cases, the precondition can be set as 200 mmHg ≤ PaO2 / FiO2(or SpO2 / FiO2) < 300 mmHg. Generally, in clinical treatment, only when the precondition is met, the current nasal high-flow oxygen therapy is considered to have a basis for evaluating the therapeutic effect. If the patient does not meet the precondition, it is considered that the nasal high-flow oxygen therapy cannot be evaluated or the evaluation result is greatly inaccurate.

[0032] The processor 22 obtains the ventilation treatment time, and generates an oxygenation respiratory index corresponding to the ventilation treatment time according to the physiological parameter and the ventilation parameter, the oxygenation respiratory index being used to evaluate the ventilation treatment effect in the ventilation treatment time corresponding to the oxygenation respiratory index. The oxygenation respiratory index includes at least one of a ROX index, an oxygenation index (P / F), an oxygen index (OI), and a pulse oxygen saturation index (OSI). The ROX index is calculated according to the following formula:

[0033]

[0034] In the formula, SpO2 and PaO2, SaO2 can be used alternatively. Assuming that SpO2 of a patient is 100%, FiO2 is 60%, and RR is 24 / min, the ROX index of the patient is 6.9.

[0035] The oxygenation index is calculated according to PaO2 / FiO2, the oxygen index is calculated according to FiO2*mean airway pressure*100 / PaO2, and the pulse oxygen saturation index is calculated according to FiO2*mean airway pressure*100 / SpO2.

[0036] The processor 22 is further configured to, when the evaluation condition is met, compare the oxygenation respiratory index with an oxygenation respiratory index threshold to obtain an oxygenation respiratory index comparison result, compare the physiological parameter with a physiological parameter threshold to obtain a physiological parameter comparison result, compare the ventilation parameter with a ventilation parameter threshold to obtain a ventilation parameter comparison result, and output a treatment suggestion according to the oxygenation respiratory index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result. The treatment suggestion can be output to the display device 30 for display. In some embodiments, the ventilation treatment auxiliary device 20 further includes a display, and the display can display the treatment suggestion. In other embodiments, the respiratory support device 10 also includes a display, and the treatment suggestion is also displayed on the respiratory support device 10.

[0037] That is, the physiological parameter and the ventilation parameter are combined in the embodiment to obtain a new index, the oxygenation respiratory index. According to the oxygenation respiratory index, the physiological parameter, and the ventilation parameter, a relevant treatment suggestion or prediction is given, which provides an effective reference for subsequent operation of a user.

[0038] The evaluation condition can be that the processor 22 starts timing the start of the ventilation therapy, that is, based on the start of timing, the oxygenation-breathing index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result are obtained in real time; the evaluation condition can also be that at least one of the physiological parameters and the ventilation parameters meets the preset condition and lasts for a preset time length, for example, when the blood oxygen saturation of the patient lasts more than 90% for one hour, the breathing index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result are obtained; or the proportion of the parameters meeting the preset condition in the physiological parameters and / or the ventilation parameters reaches a preset proportion threshold, for example, the obtained physiological parameters include blood oxygen saturation and respiratory rate, and the obtained ventilation parameters include inhaled oxygen concentration, when two of the three types of parameters meet the corresponding threshold, the oxygenation-breathing index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result are obtained; the evaluation condition can also be that the ventilation therapy time reaches a preset time length threshold, for example, the preset time length threshold includes 2 hours and 8 hours, the oxygenation-breathing index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result when the ventilation therapy time reaches 2 hours are obtained, and the oxygenation-breathing index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result when the ventilation therapy time reaches 8 hours are obtained. The following will be combined with the specific examples to explain how to give the treatment suggestion. Figure 2 An example is given to illustrate how to give the treatment suggestion, in the following example, the ventilation mode in the ventilation strategy is nasal high flow oxygen therapy, the oxygenation-breathing index is ROX index, the oxygenation-breathing index threshold is ROX index threshold, the physiological parameter is blood oxygen saturation (SpO2), the physiological parameter threshold is blood oxygen saturation threshold, and the ventilation parameter is respiratory rate (RR), and the ventilation parameter threshold is respiratory rate threshold. For other ventilation therapy modes and other types of oxygenation-breathing indexes, more or fewer oxygenation-breathing index thresholds than the example given below can be included, and more types or fewer types of physiological parameter thresholds and / or ventilation parameter thresholds can be included.

[0039] In this embodiment, a patient is receiving nasal high-flow oxygen therapy, the flow rate of which is set to 40-50 L / min, and the FiO2 is set to 100%. When the processor 22 detects that the patient meets the precondition of 200 mmHg≤PaO2 / FiO2(or SpO2 / FiO2)<300 mmHg, the timing starts. When it is determined that the ventilation treatment time reaches a first time threshold of 2 hours, the first ROX index comparison result of the ROX index with a first ROX index threshold is obtained, and the first ROX index threshold includes a first ROX safety threshold and a first ROX risk threshold. In this embodiment, the first ROX safety threshold is set to 3.85, and the first ROX risk threshold is set to 2.85. The processor 22 also obtains the first blood oxygen saturation comparison result of the blood oxygen saturation with a first blood oxygen saturation threshold, which is set to 93% in this embodiment. The processor 22 also obtains the first respiratory rate comparison result of the respiratory rate with a first respiratory rate threshold, which includes a first respiratory rate safety threshold and a first respiratory rate risk threshold. In this embodiment, the first respiratory rate safety threshold is set to 25 times / min, and the first respiratory rate risk threshold is set to 30 times / min. Then, the processor 22 outputs the corresponding first treatment suggestion according to the first ROX index comparison result, the first respiratory rate comparison result, and the first blood oxygen saturation comparison result. In this embodiment, the first treatment suggestion has several cases: one, ① ROX index≥3.85 or ② blood oxygen saturation≥93% and respiratory rate<25 times / min, indicating high HFNC success rate, and the first treatment suggestion can be “continue HFNC treatment”; two, ① ROX index<2.85 or ② blood oxygen saturation<93% and respiratory rate>30 times / min, indicating poor HFNC effect, and the first treatment suggestion can be “change ventilation strategy”. After the user sees the treatment suggestion, the patient's clinical state can be observed again. If the patient has consciousness disorder, malignant arrhythmia, severe shock, acute respiratory acidosis, etc., it can be suggested to switch from HFNC to invasive mechanical ventilation. If the patient does not have the above symptoms, it can be suggested to switch from HFNC to non-invasive ventilation; three, ① 2.85≤ROX index<3.85 or ② blood oxygen saturation≥93% and respiratory rate>25 times / min, and the first treatment suggestion can be “continue to maintain HFNC for 6 h, and closely monitor the patient's condition and vital signs”.

[0040] When the first treatment suggestion is "continue HFNC 6h, and closely monitor the condition and vital signs", the user can ventilate the treatment for 6h according to the suggestion, that is, the second length threshold is 8h, and when the ventilation treatment time reaches the second length threshold, the processor 22 obtains the second ROX index comparison result of the ROX index and the second ROX index threshold, and the second ROX index threshold includes the second ROX safe threshold and the second ROX risk threshold. In the embodiment, the second ROX safe threshold is set to 4.88, and the second ROX risk threshold is set to 3.85. The processor 22 also obtains the second blood oxygen saturation comparison result of the blood oxygen saturation and the second blood oxygen saturation threshold, and in the embodiment, the second blood oxygen saturation threshold is set to 93%. The processor 22 also obtains the second respiratory rate comparison result of the respiratory rate and the second respiratory rate threshold, and the second respiratory rate threshold includes the second respiratory rate safe threshold and the second respiratory rate risk threshold. In the embodiment, the second respiratory rate safe threshold is set to 25 times / min, and the second respiratory rate risk threshold is set to 30 times / min. Then, the processor 22 outputs the corresponding second treatment suggestion according to the second ROX index comparison result, the second respiratory rate comparison result and the second blood oxygen saturation comparison result. In the embodiment, the second treatment suggestion has several cases: one, ① ROX index ≥ 4.88 or ② blood oxygen saturation ≥ 93% and respiratory rate < 25 times / min, indicating high HFNC success rate, and the second treatment suggestion can be "continue HFNC treatment"; two, ① ROX index < 3.85 or ② blood oxygen saturation < 93% and respiratory rate > 30 times / min, indicating poor HFNC effect, and the second treatment suggestion can be "immediately intubate for invasive mechanical ventilation"; three, ① 3.85 ≤ ROX index < 4.88 or ② blood oxygen saturation ≥ 93% and respiratory rate > 25 times / min, and the second treatment suggestion can be "continue HFNC 12h, and closely monitor the condition and vital signs".

[0041] When the second treatment suggestion is "continue HFNC for 12 hours and closely monitor the patient's condition and vital signs", the user can continue the ventilation treatment for 12 hours according to the suggestion, that is, the third time threshold is 20 hours, and when the ventilation treatment time reaches the third time threshold, the processor 22 obtains the third ROX index comparison result of the ROX index and the third ROX index threshold, and the third ROX index threshold includes the third ROX risk threshold, and in the embodiment, the third ROX risk threshold is set to 4.88. The processor 22 also obtains the third blood oxygen saturation comparison result of the blood oxygen saturation and the third blood oxygen saturation threshold, and in the embodiment, the third blood oxygen saturation threshold is set to 93%, and the processor 22 also obtains the third respiratory rate comparison result of the respiratory rate and the third respiratory rate threshold, and the third respiratory rate threshold includes the third respiratory rate risk threshold, and in the embodiment, the third respiratory rate risk threshold is set to 25 times / min. Then, the processor 22 outputs the corresponding third treatment suggestion according to the third ROX index comparison result, the third respiratory rate comparison result and the third blood oxygen saturation comparison result. In the embodiment, the third treatment suggestion has several cases: one, ① ROX index ≥ 4.88 or ② blood oxygen saturation ≥ 93% and respiratory rate < 25 times / min, indicating high success rate of HFNC, and the third treatment suggestion can be "continue HFNC treatment and closely observe vital signs"; two, ① ROX index < 4.88 or ② blood oxygen saturation ≥ 93% and respiratory rate > 25 times / min, indicating poor HFNC effect, and the third treatment suggestion can be "immediately intubate for invasive mechanical ventilation".

[0042] The above-mentioned thresholds can be pre-built in the system, or can be set by the user before the ventilation treatment, or can be modified during the ventilation treatment based on the operation instruction input by the user, for example, when the ventilation treatment time is between 0 hours and 2 hours, the user can set the corresponding oxygenation respiratory index threshold, physiological parameter threshold and ventilation parameter threshold between 2 hours and 8 hours.

[0043] In some embodiments, the processor can also acquire the comparison results of the oxygenation-breathing index, the ventilation parameters and the physiological parameters in real time or at intervals, and perform statistics on the comparison results of the oxygenation-breathing index, the ventilation parameters and the physiological parameters in a ventilation treatment time period. The statistics of the comparison results of the oxygenation-breathing index, the ventilation parameters and the physiological parameters can be used to determine the severity or frequency of the fluctuations of the oxygenation-breathing index, the ventilation parameters or the physiological parameters in the ventilation treatment time period. The processor can output corresponding treatment suggestions or predictions according to the statistics. For example, the threshold of the oxygenation-breathing index is a first reference threshold, the threshold of the ventilation parameters is a second reference threshold, and the threshold of the physiological parameters is a third reference threshold. The comparison results of the oxygenation-breathing index in a first time threshold can be statistically analyzed. If the number, proportion or time length of the oxygenation-breathing index exceeding the first reference threshold exceeds a set threshold, it means that the severity or frequency of the fluctuations of the oxygenation-breathing index exceeds an acceptable range. In this case, the processor can output a treatment suggestion of "changing the ventilation strategy". Similarly, the comparison results of the ventilation parameters and the second reference threshold and the comparison results of the physiological parameters and the third reference threshold can be used to determine whether the severity or frequency of the fluctuations of the physiological parameters and the ventilation parameters exceeds an acceptable range, and output corresponding treatment suggestions based thereon.

[0044] The above treatment suggestions are only examples. The treatment suggestions can include suggestions of continuing the current ventilation strategy, changing to a ventilation strategy with stronger respiratory support capability or changing to a ventilation strategy with weaker respiratory support capability, prompting the user to adjust the parameters in the ventilation strategy, or using lung recruitment and other treatment methods.

[0045] In another embodiment, the present application also provides another medical device system. The medical device system includes a plurality of medical devices, which can include but are not limited to a ventilator, an anesthesia machine, an oxygen therapy device, a monitor, a central station, a medical information system and a medical mobile terminal. The medical information system can be, for example, a HIS, and the medical mobile terminal can be a PDA or a mobile PC, a mobile phone and the like held by medical staff. At least one of the plurality of medical devices can acquire physiological parameters and ventilation parameters of a patient in a ventilation treatment. The physiological parameters and the ventilation parameters have the same meanings as those in the above embodiment.

[0046] The difference between the present embodiment and the previous embodiment is that one or more medical devices in the present embodiment jointly play the role of the ventilation therapy auxiliary device 20 in the previous embodiment. For example, the medical devices can include a ventilator, a monitor, and a central station, the ventilator can acquire ventilation parameters of the patient and send the ventilation parameters to the central station, the monitor can acquire physiological parameters of the patient and also send the physiological parameters to the central station, the central station can start timing when it is detected that the timing condition is met, obtain a ventilation therapy time according to the timing, and generate an oxygenation-breathing index corresponding to the ventilation therapy time according to the physiological parameters and the ventilation parameters, and the central station also compares the oxygenation-breathing index with an oxygenation-breathing index threshold value when it is detected that the evaluation condition is met, acquires an oxygenation-breathing index comparison result, compares the physiological parameters with physiological parameter threshold values, acquires a physiological parameter comparison result, compares the ventilation parameters with ventilation parameter threshold values, acquires a ventilation parameter comparison result, and outputs a treatment suggestion according to the oxygenation-breathing index comparison result, the physiological parameter comparison result, and the ventilation parameter comparison result. The central station processes the physiological parameters and the ventilation parameters basically in the same way as the ventilation therapy auxiliary device 20 processes the ventilation parameters and the physiological parameters in the previous embodiment.

[0047] As can be seen, although the ventilation therapy auxiliary device 20 is not provided in the medical device system in the present embodiment, a new index for assisting in evaluating the effect of ventilation therapy, i.e., the oxygenation-breathing index, can still be obtained according to the physiological parameters and the ventilation parameters, and a corresponding treatment suggestion can be given according to subsequent comparisons.

[0048] In the above embodiments, the obtained physiological parameters and ventilation parameters can be effectively utilized to provide corresponding ventilation treatment suggestions to users, thereby helping medical staff to judge or predict the effect of ventilation and prompting the medical staff to timely switch the ventilation therapy mode, so as to achieve the effects of shortening the time of putting the patient on the machine and improving the prognosis.

When all or part of the functions in the above embodiments are implemented by computer programs, the program can be stored in a computer-readable storage medium, which may include: read-only memory, random access memory, disk, optical disk, hard disk, etc., and the program is executed by a computer to achieve the above functions.
