An apparatus for controlling gas delivery to a patient is disclosed, wherein delivery is adapted to maintain a physiological sleep state. The apparatus includes a monitoring device that monitors EEG, EOG, EMG, patient position and patient breathing. The apparatus also contains a microprocessor, which is programmed to derive sleep state specific indicators from the data received by the monitoring device and to determine if the sleep state is in a stable or deteriorating phase, where upon gas pressure will be automatically adjusted to maintain the sleep state if desired. The microprocessor is programmed with a unique automatic sleep staging algorithm and a gas pressure seek algorithm which work together to automatically adjust delivered respiratory gas pressure to a user based upon the determined sleep state and the sleep states condition.

1. An apparatus for controlling gas delivery to a patient to enhance sleep efficiency of the patient during the gas delivery, said apparatus including:a monitoring component adapted to monitor at least one sleep state physiological variable of a patient during an application of a positive gas pressure to an airway of the patient, to provide monitoring information representing the at least one sleep state physiological variable; and a digital processing component programmed to include a deriving component in communication with the monitoring component, said deriving component comprising a sleep staging algorithm to automatically derive a plurality of sleep states of the patient based on the monitoring information, the plurality of sleep states including at least two sleep states selected from the group comprising sleep stages 1-4, REM, micro-arousal, arousal and wake, corresponding to the at least one sleep state physiological variable; said digital processing component further including a pressure value determining component receiving said plurality of sleep states to determine a plurality of gas pressure values, each one of the gas pressure values corresponding to each one of the sleep states, said gas pressure values being applicable to control a gas delivery device to control said positive gas pressure in accordance with the gas pressure values.
