Abstract
A turbine ventilator pressure-controlled ventilation method comprising the following steps: a ventilator is started up, a control unit in the ventilator controls a turbine motor to rotate at rotational speed U, the turbine motor provides the ventilator with a hyperbaric gas; a detector unit detects the breathing state of a patient, if the patient is in an inhalation state, proceeds to an inhalation phase control, and, if the patient is in an exhalation state, proceeds to an exhalation phase control; the air pressure of an inhalation phase is controlled by the control unit by controlling driving voltage V1 of an inhalation valve to regulate the extent to which the inhalation valve is opened, the positive end-expiratory pressure of an exhalation phase is controlled by the control unit by controlling driving voltage V2 of an exhalation valve to regulate the extent to which the exhalation valve is opened.
