Methods and apparatus for adaptable pressure treatment of sleep disordered breathing

摘要

Disclosed is a respiratory pressure treatment apparatus including a flow generator to generate a flow of breathable gas to a patient interface; and a controller. The controller controls the flow generator to deliver the flow of breathable gas at the patient interface. The flow of breathable gas is synchronized with a respiratory cycle and includes expiratory pressure portions and inspiratory pressure portions. At least one of the expiratory pressure portions is at a pressure lower than the pressure of at least one of the inspiratory pressure portions. The controller also controls an activation of a pre-termination pressure treatment protocol during a pre-termination period wherein a change to control parameters for setting pressure of the inspiratory pressure portions or the expiratory pressure portions during a period that immediately precedes an anticipated or detected ending of a treatment session is initiated.
