摘要：
Disclosed is a method of controlling a respiratory pressure treatment device. The method includes generating a flow of breathable gas at a patient interface, the flow of breathable gas being synchronized with a respiratory cycle. The flow of breathable gas includes inspiratory pressure portions (ins) and expiratory pressure (exp) portions such that an expiratory pressure portion (exp) is at a pressure lower than an inspiratory pressure portion (ins). A flow of breathable gas to the patient interface is measured and the measurement is analysed to detect an occurrence of a sleep disordered breathing (SDB) event. Control parameters of an expiratory pressure portion (exp) are modified in response to the detection of the occurrence of the SDB event, to modify a reduction in expiratory pressure delivered during the expiratory pressure portion (exp). The SDB event consists a persistent obstruction to flow.
