Description
Technical field
The present invention relates to the lung recruitment technical field in armarium, particularly relate to a kind of lung recruitment ventilation control method and device.
Background technology
Alveolar is the position of gas exchange, and adult's alveolar amounts to 3 ~ 400,000,000, for gas exchange provides enough areas.Alveolar epithelial cells has two types, a kind of disperse of responsible gas; Another kind ofly can form one deck liquid film at alveolar surface, to reduce the surface tension of alveolar, keep alveolar expand and be unlikely to occur alveolar collapse in end-tidal.
Have data to show, induction of anesthesia patient occurs that pulmonary atelectasis incidence rate is more than 90%.In anesthesia art and postoperative, owing to applying various analgesic, expectoration function that tranquilizer inhibits respiratory tract, the unable expectoration of secretions of thickness, can block bronchia.If art Bi Wei makes two lung fully expand, Postoperative Analgesia After imperfection, patient can not firmly breathe, and makes the expansion of lung limited, and alveolar can be caused to occur the situation of pulmonary atelectasis.
The clinical harm of pulmonary atelectasis mainly comprises: (1) causes hypoxemia; (2) alveolar surfactant is caused to be lost (promoting that cycle of alveolar subsides to persistence to subside development); (3) expiratory airflow is caused to be obstructed; (4) periodically alveolar collapse causes multiple tensile injury of lung with multiple; (5) pulmonary infection is increased the weight of; (6) biological injury of lung is caused.
When the situation of pulmonary atelectasis appears in alveolar, need to adopt lung recruitment method to realize withering multiple of alveolar.Lung recruitment refers to and intermittently to give higher than the pressure of conventional Map or volume at mechanical ventilation and to maintain the regular hour, and the alveolar that makes to wither obtains the process of multiple.The common method of existing lung recruitment mainly contains following several: controlling works method (SI); Exhale last malleation (positiveexpiratoryendpressure, PEEP) incremental method; High level pressure controling method (PCV); And sigh method.
Wherein, controlling works method (SI), adopt constant voltage ventilating mode, pressure of inspiration(Pi) is 30 ~ 45cmH2O, and the persistent period is between 30 ~ 50s, namely gives enough pressure when air-breathing starts and continues time enough, making alveolar fully opening of subsiding.Controlling works method is current the most frequently used lung recruitment method, but it is larger to hemodynamics interference.
PEEP incremental method progressively improves PEEP on original PEEP horizontal base, each raising 5cmH2O also keeps a period of time, until think that alveolar multiple stopping increases PEEP, then reduce PEEP gradually, finally adopt higher than best PEEP ventilation during alveolar collapse.
High level pressure controling method (PCV), is increased to 20cmH2O by PEEP, then Stress control level is increased to 40 ~ 45cmH2O, maintains 30 ~ 60s.
Sigh method is that interruption gives larger tidal volume or larger pressure (namely sighing) makes lung recruitment.The frequency of sighing and size can regulate, but specific implementation method is incomplete same.
But if excessive in the fluctuation of lung recruitment process hemodynamic parameter, need to stop Recruitment maneuver, specific targets require as follows:
Systolic pressure (SBP): systolic pressure is down to 90mmHg or than multiple front decline 30mmHg, should be stopped multiple immediately;
Heart rate HR: heart rate is increased to 140bpm or increases 20bpm before multiple, should stop multiple immediately;
Blood oxygen saturation SpO2: be down to 90% or a ratio front reduction by more than 5% again, should stop immediately opening again;
Arrhythmia: arrhythmia occurs, should stop multiple immediately;
Mean arterial pressure MAP:MAP < 60mmHg, should stop multiple immediately;
The development (CT image) of windage, stops multiple;
Mean arterial pressure MAP, heart rate HR and cardiac output CO: change is more than 15% ~ 20% compared with before multiple, stops lung recruitment process immediately.
And the existing equipment (as anesthetic machine) with lung recruitment function, normally need manually to regulate breathing machine ventilation pattern parameters to realize lung recruitment, lung recruitment function only provide surge pressure (Ppeak), exhale last malleation (PEEP), the short trend of the lung recruitment relevant parameter such as compliance (Compl), carbon dioxide output (VeCO2).There is following weak point in it:
First, each stage of lung recruitment process is all realized by doctor's manual adjustments ventilating mode parameters, needs to reset ventilation parameters, inconvenient operation after having opened again;
Secondly, if abnormal state in lung recruitment process, can not quickly recover at any time and open previous state again, because ventilation parameters has been modified, even repeatedly be have modified, doctor is difficult to, when in a rush, ventilating mode parameters is returned to the state before lung recruitment.
