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. |
