The application relates to an adaptive pressure and oxygen concentration control method. The adaptive pressure and oxygen concentration control method comprises the steps of S10, carrying out online identification on respiratory process dynamic parameters, and respectively calculating a linearized gas path damping coefficient Rrs and a linearized dynamic smoothing coefficient Crs; S20, estimatingadaptive parameters theta according to the linearized gas path damping coefficient Rrs and the linearized dynamic smoothing coefficient Crs; S30, calculating the air-oxygen mixed flow control signal ue in combination with the adaptive parameters theta to implement pressure adaptive control; and S40, calculating an air flow control signal uea and an oxygen flow control signal ueo in combination with the adaptive parameters theta to achieve adaptive control over oxygen concentration. The adaptive pressure and oxygen concentration control method synchronizes the pressure maintenance process withthe oxygen concentration maintenance process. The adaptive pressure and oxygen concentration control method is simple and easy to implement, and can ensure the simultaneous adjustment of the pressureand the oxygen concentration without increasing the complexity of a ventilator, thereby ensuring the clinical use effect of the ventilator.
