    Abstract: 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.

    Abstract: Methods and apparatus provide acoustic detection for automated devices such as respiratory treatment apparatus. In some embodiments of the technology, acoustic analysis of noise or sound pulses, such as a cepstrum analysis, based on signals of a sound sensor (104) permits detection of obstruction (0) such as within a patient interface, mask or respiratory conduit (108) or within patient respiratory system. Some embodiments further permit detection of accessories such as an identification thereof or a condition of use thereof, such as a leak. Still further embodiments of the technology permit the detection of a patient or user who is intended to use the automated device. C-)J 0o (D Z3 w 0) (D ~ U U-U

    Abstract: Respiratory pressure treatment apparatus include automated methodologies for controlling changes to pressure in the presence of sleep disordered breathing events. In an example apparatus, various levels of expiratory pressure relief can provide different pressure reductions for patient comfort during expiration (333-A, 333-B, 333-C). The control parameters for these levels may be automatically modified based on the detection of an open airway. Similarly, in some embodiments, the levels may be automatically adjusted based on a detection of persistent obstruction. In still further embodiments, control parameters associated with a rise time of an early portion of an inspiratory pressure treatment may be automatically adjusted upon detection of flow limitation to permit a change to more aggressive waveforms from more comfortable waveforms for the treatment of sleep disordered breathing events.

    Abstract: An apparatus (10) for supplying breathable gas. The apparatus (10) includes a flow generator (12), a gas outlet (14), a connection means (21) interposed between the flow generator (12) and the pressure sensing means (20), the connection means having a connecting inlet (22) and a connecting outlet (24), a pressure sensing means (20) interposed between the connecting outlet (24) and the gas outlet (14). The connecting means (21) is adapted to allow selective connection to either a duct member (30) providing a direct flow path from the connecting inlet (22) to the connecting outlet (24) or to a humidifier (26) interposed between the connecting inlet (22) and the connecting outlet (24).
