An apparatus is provided for controlling gas delivery to a patient, to maintain effective respiratory function. The apparatus includes sensors for monitoring one or more physiological variables such as breathing airflow sound, EEG, EOG, ENG, and/or patient position. The apparatus includes a determining component for deriving, from the sensed variables, data representing a respiratory event and a component for determining from the data a gas pressure or modulated gas pressure to counteract tissue vibration associated with the respiratory event, thereby tending to cancel the respiratory event. The determining component may include an algorithm adapted to generate a gas pressure signal substantially 180 degrees out of phase relative to the tissue vibration. The apparatus may include a drug delivery module operable to deliver a drug in accordance with the sensed physiological variable and the determining component.

1. An apparatus for controlling gas delivery to a patient to maintain effective respiratory function, said apparatus including:a monitoring component adapted to monitor at least one 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 physiological variable; and a processing component including a deriving component in communication with the monitoring component, adapted to receive the monitoring information and, based on the monitoring information, to derive data representing a respiratory event characterized by a vibration of body tissue along the airway; said processing component further including a determining component coupled to receive said data and including an algorithm operable to generate a control signal based on said data, said control signal being substantially 180 degrees out of phase relative to said data and being applicable to control a gas delivery device to modulate said positive gas pressure in a manner to counteract said vibration of the body tissue, thereby tending to cancel the respiratory event.
