1. Apparatus for treating a respiratory disorder comprising:
- a pressure device, anda controller, including at least one processor, configured to control the pressure device to;
supply, upon initiation of treatment, a flow of pressurised air to the airway of a patient at a treatment pressure according to a pre-sleep profile of pressure versus time,increase, upon detection of sleep onset of the patient, the treatment pressure to a predetermined therapeutic pressure according to a bridging profile of pressure versus time, andsupply the flow of pressurised air to the airway of the patient at a therapeutic pressure,wherein the controller is configured to detect the sleep onset by detecting;
few or no respiratory disturbances occurring within a predetermined interval, the predetermined interval being a predetermined time or predetermined breath count, wherein, by monitoring respiratory flow derived from a flow transducer, the controller detects few or no respiratory disturbances to detect the sleep onset by testing lack of variation during the predetermined interval of expiratory peak flow location.
