Abstract

This invention is an apparatus (110) for delivering pressurized gas to the airway of a patient including the following: a gas flow generator (114) for providing a flow of gas, a breathing appliance (120) for sealingly communicating with the airway of the patient, and a conduit (118) for delivery of the gas flow to the airway of the patient. The conduit has a first end connected to the gas flow generator, and a second end connected to the breathing appliance. The apparatus further includes at least one sensor (126) in fluid communication with the conduit, located substantially at the gas flow generator for detecting conditions corresponding to breathing patterns of the patient, which generates signals corresponding to the conditions, and an information processor for receiving the signals that controls the output of the gas flow generator responsive to the signals.
