Abstract
A ventilator turbine volume-controlled ventilation method comprises the main steps of: the ventilator is started up, a control unit in the ventilator issues a rotation speed U control instruction to a turbine driver, the turbine driver drives a turbine motor, and then the control unit detects the breathing state of a patient, if the patient needs to inhale air, proceeds to an inhalation phase control, and, if the patient needs to exhale air, proceeds to an exhalation phase control, where the inhalation phase control is implemented by the control unit that outputs driving voltage V1 to regulate the extent to which an inhalation valve is opened, and the exhalation phase control is implemented by the control unit that outputs driving voltage V2 to regulate the extent to which an exhalation valve is opened.
