Abstract

The application discloses an adjustable positive and negative pressure synchronized control system, mode selection and initialization, wherein medical staff selects an adjustable positive and negative pressure synchronized ventilation (APNSV) mode according to the patient's condition and treatment demand; parameter monitoring and judgment, including inspiratory support monitoring and judgment and expiratory support monitoring and judgment; and the application accurately selects the APNSV mode according to the patient's treatment demand, and sets inspiratory negative cuirass pressure (INCP) and expiratory cuirass pressure (ECP) parameter default values according to the patient's basic condition.
