Apparatus for controlling gas or drug delivery to a patient, said delivery being adapted to matintain effective respiratory function. The apparatus includes means for monitoring one or more physiological variables such as breathing airflow sound, EEG, EOG, EMG and/or patient position associated with the patient. The apparatus also includes means for deriving from the variables, data representing a physiological state associated with the patient and means for determining from the data, a gas pressure or drug quantity which substantially prevents a deterioration in the state. The determining means may include an algorithm adapted to generate a gas pressure signal which is substantially 180 out of phase relative to the phase of the patient breathing and/or sound. The apparatus may include a gas delivery means for delivering gas to the patient in accordance with the determined gas pressure. The apparatus may include a drug delivery module for delivering a drug to the patient. |
