Description
TECHNICAL FIELD
[0001] The present application relates to the field of medical ventilation, in particular to a ventilation system, device and method for realizing heart-lung interaction assessment function. BACKGROUND
[0002] Invasive ventilator is a medical ventilation device for supporting the respiratory function of patients, which is widely used in clinical intensive care, emergency and surgical anesthesia. The ventilator device provides multiple working modes, including: pressure-controlled ventilation (PCV), volume-controlled ventilation (VCV), pressure support ventilation (PSV), synchronized intermittent mandatory ventilation (SIMV), airway pressure release ventilation (APRV), continuous positive airway pressure ventilation (CAPA). As shown in the following table, the ventilation device includes the following basic structures: control console, air-oxygen mixer, turbine, valve, sensor and airway pipeline, etc. Figure 1
[0003] Heart-lung interaction refers to the phenomenon that the two important organs of heart and lung affect and interact with each other through anatomical structure and functional relationship in physiological and pathological states, and such interaction is crucial for assessing and judging the hemodynamic state. Specifically, during the breathing process, the changes in the lung and chest will affect the blood flow output of the heart, thereby affecting the hemodynamics of the whole body as shown in the following table. Figure 2
[0004] In clinical treatment, mechanical ventilation (i.e. ventilator-assisted breathing) is a common support means. After the application of mechanical ventilation, the intrathoracic pressure (such as the pressure rise caused by positive pressure ventilation) will change, which not only affects the pumping function of the heart, but also has a significant impact on the entire circulatory system. The ventilator device can help or replace the patient's breathing, has multiple ventilation modes and adjustment parameters, and the doctor can adjust these modes and parameters according to different clinical needs to meet the needs of hemodynamic assessment.
[0005] Based on previous research and clinical experience, medical professionals have established several methods based on cardiopulmonary interaction to assist in the assessment of hemodynamic status, such as pulse pressure variation (PPV), beat-to-beat variation (SVV), end-expiratory occlusion testing, and venous return curve measurement. However, in practice, these methods often require physicians to manually adjust the ventilator's operating mode and ventilation parameters. The entire operation is relatively complex, requiring constant adjustments and measurements based on the patient's respiratory status, which undoubtedly increases the difficulty and tediousness of the assessment. Therefore, in the fast-paced and high-pressure environments of emergency and critical care, the widespread application and promotion of these methods is limited by the practical complexity of the operation. This has hindered the clinical adoption of methods based on cardiopulmonary interaction to assess hemodynamic status, and also affected the clinical applicability and promotion of cardiopulmonary interaction to determine hemodynamic status.
[0006] Furthermore, past research and clinical practice have primarily focused on the value of mechanical ventilation within the respiratory system itself, with hemodynamic assessment typically considered merely an auxiliary function of the ventilator. This has also led to a greater emphasis on traditional respiratory support modes in the development of related equipment. Currently, the process of utilizing cardiopulmonary interaction to assess hemodynamics remains complex and cumbersome. Physicians must manually set and adjust ventilation parameters (such as positive end-expiratory pressure, respiratory rate, and tidal volume) based on the patient's actual respiratory condition and the mechanical ventilation mode used. During the assessment process, measurement timing and methods must be repeatedly adjusted based on changes in the respiratory cycle. All of these steps significantly increase the physician's workload and the difficulty of assessment. Summary of the Invention

DETAILED DESCRIPTION
[0023] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0024] like Figure 3 As shown, a ventilation system that realizes the cardiopulmonary interactive assessment function includes: Standard ventilation module, which is used to provide multiple standard ventilation modes; a storage module, configured to store ventilation parameter standard values and ventilation parameter event values corresponding to various standard ventilation modes among the plurality of standard ventilation modes; an initial selection module, configured to select a corresponding standard ventilation mode from the plurality of standard ventilation modes as an initial ventilation mode according to the clinical condition of the target subject, and set the ventilation mode to the initial ventilation mode; A ventilation event module, which is used to provide multiple ventilation events; An event switching module, configured to select a corresponding ventilation event from the plurality of ventilation events as a target ventilation event according to clinical needs; A ventilation control module is used to perform ventilation control according to the standard value of the ventilation parameter of the initial ventilation mode; it is also used to switch the ventilation mode between the initial ventilation mode and the corresponding standard ventilation mode according to the target ventilation event, and to perform ventilation control according to the ventilation parameter event value of the switched standard ventilation mode.
[0025] The present invention provides a ventilation system that realizes the cardiopulmonary interaction evaluation function and can automatically adjust the ventilation mode and intelligently set the ventilation parameters, thereby reducing the burden of doctors on repeated manual adjustment, measurement and judgment based on the patient's breathing and ventilation status, simplifying the evaluation process, and improving clinical work efficiency, so as to solve the problem of complexity and tediousness of ventilation equipment in evaluating the hemodynamic status based on cardiopulmonary interaction.
[0026] The present invention can automatically adjust the ventilation mode and uniformly set ventilation parameters under the condition of preset event triggering, so as to optimize the hemodynamic assessment process, reduce human intervention, improve ease of use and clinical applicability, fill the technical gap in the hemodynamic assessment function of existing ventilation equipment, and improve the efficiency and accuracy of clinical operations.
[0027] In some embodiments: The standard ventilation module is used to provide multiple standard ventilation modes. The multiple standard ventilation modes include at least a standard VCV (volume-controlled ventilation) mode and a standard PCV (pressure-controlled ventilation) mode. In addition, the multiple standard ventilation modes may also include a V-SIMV (Volume Synchronized Intermittent Mandatory Ventilation) mode, a P-SIMV (Pressure-Synchronized Intermittent Mandatory Ventilation) mode, a CAPA (continuous positive airway pressure ventilation) mode, and a PSV (pressure support ventilation) mode.
[0028] Different standard ventilation modes correspond to different ventilation parameters. For example: The ventilation parameters of standard VCV mode are as follows: 1) Tidal volume (Vt): The amount of gas delivered to the patient by the ventilator each time, expressed in mL; 2) Respiratory rate (RR): the number of breaths per minute, expressed in breaths / minute; 3) Inspiratory to expiratory ratio (I:E): the ratio of inspiratory time to expiratory time in each respiratory cycle; 4) Positive end-expiratory pressure (PEEP): maintains a level higher than atmospheric pressure in the airway at the end of expiration, which can prevent alveolar collapse and promote oxygenation, expressed in cmH2O; 5) Inspired oxygen concentration (FiO2): The percentage of oxygen in the gas output by the ventilator.
[0029] The ventilation parameters of standard PCV mode are as follows: 1) Pressure control (PC): The set airway pressure during inhalation, also known as inspiratory pressure. 2) Respiratory rate (RR): the number of breaths per minute, expressed in breaths / minute; 3) Inspiratory to expiratory ratio (I:E): the ratio of inspiratory time to expiratory time in each respiratory cycle; 4) Positive end-expiratory pressure (PEEP): maintains a level higher than atmospheric pressure in the airway at the end of expiration, which can prevent alveolar collapse and promote oxygenation, expressed in cmH2O; 5) Inspired oxygen concentration (FiO2): The percentage of oxygen in the gas output by the ventilator.
[0030] In some embodiments: The storage module stores ventilation parameter standard values and ventilation parameter event values corresponding to various standard ventilation modes among the multiple standard ventilation modes.
[0031] For example, for the ventilation parameters of the standard VCV mode, the standard values of the ventilation parameters are: Vt = 400 mL, RR = 14 times / min, I:E = 1:2, PEEP = 8 cmH2O, and FiO2 = 55%.
[0032] In some embodiments: The initial selection module is used to select a corresponding standard ventilation mode from the multiple standard ventilation modes as the initial ventilation mode according to the clinical condition of the target subject. For example, if the selected initial ventilation mode is the standard VCV mode, please refer to the specific mode diagram. Figure 4 ; Among them, ① is the respiratory waveform; ② is the setting mode (the gray background and red mark indicate the currently selected standard ventilation mode, i.e. the initial ventilation mode); ③ is the setting parameters; ④ is the adjustment knob; ⑤ is the real-time display of the parameter results; ⑥ is the target object information; ⑦ is the external device connection port; ⑧ is the data export interface.
[0033] After the initial ventilation mode is selected, the system controls the ventilation process according to the standard values of the ventilation parameters of the initial ventilation mode.
[0034] In some embodiments: The multiple ventilation events include PPV / SVV measurement ventilation events, venous return curve measurement ventilation events and end-expiratory occlusion ventilation events.
[0035] Preferably, when the target ventilation event is the PPV / SVV measurement ventilation event, the ventilation control module is specifically configured to: The ventilation mode is switched from the initial ventilation mode to the standard VCV mode, and ventilation control is performed according to the ventilation parameter event value of the standard VCV mode.
[0036] Specifically, in the PPV / SVV measurement ventilation event, the ventilation parameter event value of the standard VCV mode can be set as follows: Vt = 10 mL x ideal body weight (IBW) (kg) RR = 12 breaths / min I:E = 1:2 PEEP = 5 cmH2O FiO2 = consistent with the initial ventilation mode settings.
[0037] At this time, the interface effect of the ventilation system for realizing the heart-lung interaction evaluation function according to the present application is as shown in Figure 5 .
[0038] Preferably, when the target ventilation event is the venous return curve measurement ventilation event, the ventilation control module is specifically used for: switching the ventilation mode between the initial ventilation mode and the standard PCV mode multiple times, and performing ventilation control according to the ventilation parameter standard value of the initial ventilation mode when the ventilation mode is the initial ventilation mode, and performing ventilation control according to the ventilation parameter event value of the standard PCV mode when the ventilation mode is the standard PCV mode.
[0039] Further, the ventilation parameter event value of the standard PCV mode has multiple gears; the ventilation control module is specifically used for: switching the ventilation mode from the initial ventilation mode to the standard PCV mode, and performing ventilation control according to the ventilation parameter event value of the current gear of the standard PCV mode, and controlling ventilation pause at the end of inspiration for a first preset time; after the first preset time is up, switching the ventilation mode to the initial ventilation mode, and performing ventilation control according to the ventilation parameter standard value of the initial ventilation mode for a second preset time; after the second preset time is up, switching the ventilation mode to the standard PCV mode, and performing ventilation control according to the ventilation parameter event value of the next gear of the standard PCV mode until the circulation of all gears is completed, and switching the ventilation mode to the initial ventilation mode after the circulation of all gears is completed.
[0040] Specifically, the ventilation parameter event value of the standard PCV mode has four gears, which are specifically as follows: Gear one: PEEP = 5 cmH2O, PC = 0 cmH2O, and maintaining end-inspiration pause for 12 seconds after one gas delivery; Gear two: PEEP = 5 cmH2O, PC = 10 cmH2O, and maintaining end-inspiration pause for 12 seconds after one gas delivery; Position 3: PEEP = 5 cmH2O, PC = 20 cmH2O, maintain an inspiratory pause for 12 seconds after one breath; Position 4: PEEP = 5 cmH2O, PC = 30 cmH2O, maintain an inspiratory pause for 12 seconds after one air delivery.
[0041] Venous return curve measurement of ventilation events is based on PCP; gear 1: PEEP = 5 cmH2O, PC = 0 cmH2O, after a single breath, switch to end-inspiratory pause, achieve a plateau pressure of 5 cmH2O, and continue for 12 seconds before returning to the initial ventilation mode; gear 2: PEEP = 5 cmH2O, PC = 10 cmH2O, after a single breath, switch to end-inspiratory pause, achieve a plateau pressure of 15 cmH2O, and continue for 12 seconds before returning to the initial ventilation mode; gear 3: PEEP = 5 cmH2O, PC = 20 cmH2O, after a single breath, switch to end-inspiratory pause, achieve a plateau pressure of 25 cmH2O, and continue for 12 seconds before returning to the initial ventilation mode; gear 4: PEEP = 5 cmH2O, PC = 30 cmH2O, after a single breath, switch to end-inspiratory pause, achieve a plateau pressure of 35 cmH2O, and continue for 12 seconds before returning to the initial ventilation mode. Each initial model interval is 1 minute, and then it automatically switches to the next gear.
[0042] The ventilation control process for measuring ventilation events using the venous return curve is as follows: in each gear, after a 12-second pause at the end of inspiration, the device automatically switches to the initial ventilation mode and maintains it for 1 minute. It then switches to the next gear, cycling through all gears and returning to the initial mode. Furthermore, the FiO2 remains consistent with the initial ventilation mode setting to ensure continuous oxygen delivery.
[0043] Preferably, when the target ventilation event is the end-expiratory blocked ventilation event, the ventilation control module is specifically configured to: Switching the initial ventilation mode to the standard VCV mode, and performing ventilation control according to the ventilation parameter event value of the standard VCV mode and maintaining the ventilation for a third preset time (e.g., 15 seconds); After the third preset time expires, the ventilation mode is switched to the initial ventilation mode, and ventilation control is performed according to the standard value of the ventilation parameter of the initial ventilation mode.
[0044] In the event of end-expiratory occlusion ventilation, the ventilation parameter event values of the standard VCV mode can be set as follows: Vt = 8 mL × ideal body weight (IBW) (kg) PEEP = 5 cmH2O FiO2 = consistent with the setting value of the initial ventilation mode. In some embodiments, the system of the present invention further includes: A data calculation module is used to calculate the ideal weight according to the height and actual weight of the target object, and calculate the tidal volume event value according to the ideal weight.
[0045] Specifically, for men: IBW = Wt + 0.91 * (Ht - 152.4 cm); for women: IBW = Wt + 0.91 * (Ht - 152.4 cm). Here, IBW represents ideal body weight, Wt represents actual body weight, and Ht represents height. Based on the aforementioned ventilation system that implements a cardiopulmonary interactive assessment function, the present invention also provides a ventilation device that implements this function.
[0046] A ventilation device that implements a cardiopulmonary interaction evaluation function includes a processor, a memory, and a computer program stored in the memory. The computer program is executed by the processor to implement the functions of the ventilation system that implements the cardiopulmonary interaction evaluation function as described above.
[0047] Based on the above-mentioned ventilation system for realizing the cardiopulmonary interactive evaluation function, the present invention also provides a ventilation method for realizing the cardiopulmonary interactive evaluation function.
[0048] A ventilation method for realizing a cardiopulmonary interactive evaluation function, applied to the ventilation system for realizing a cardiopulmonary interactive evaluation function as described above, comprising: Providing multiple standard ventilation modes, and storing ventilation parameter standard values and ventilation parameter event values corresponding to various standard ventilation modes in the multiple standard ventilation modes; selecting a corresponding standard ventilation mode from the plurality of standard ventilation modes as an initial ventilation mode according to the clinical condition of the target subject, setting the ventilation mode to the initial ventilation mode, and performing ventilation control according to standard values of ventilation parameters of the initial ventilation mode; A plurality of ventilation events are provided, and a corresponding ventilation event is selected from the plurality of ventilation events as a target ventilation event according to clinical needs, and the ventilation mode is switched between the initial ventilation mode and the corresponding standard ventilation mode according to the target ventilation event, and ventilation control is performed according to the ventilation parameter event value of the switched standard ventilation mode.
[0049] The interaction between the heart and lungs is affected by their shared anatomical position and direct vascular connection in the chest cavity. Since the heart is located in the chest cavity, fluctuations in intrathoracic pressure during the respiratory cycle significantly affect the pressure applied to the heart, further affecting changes in hemodynamics, which can be used for circulatory assessment. On this basis, the present invention is able to achieve key functions including PPV, SVV measurement, venous return curve drawing, and end-expiratory occlusion circulation assessment. The core advantage of the present invention is that through the preset physiological model, it can automatically adjust to the corresponding preset parameters in real time according to the event, significantly reducing the manual operations required by medical staff in the management of complex diseases. In addition, the device exhibits the following outstanding advantages in intensive care and emergency applications: 1. Significantly improved operational efficiency: Through automatic parameter adjustment, the cycle evaluation process is optimized, improving the work efficiency of medical staff; 2. Improve process standardization: Through automation and pre-set standard modes and parameters, reduce non-standard deviations caused by manual intervention by different personnel; 3. Adapt to complex conditions: Accurately respond to dynamic changes in patients and fully meet diverse and personalized circulatory monitoring and evaluation needs.
