Abstract
Apparatus for delivering pressurized gas to the airway of a patient including: a gas flow generator for providing a flow of gas, a breathing appliance for sealingly communicating with the airway of the patient, and a conduit for delivery of the gas flow to the airway of the patient, the conduit having 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 in fluid communication with the conduit and located substantially at the gas flow generator for detecting conditions corresponding to breathing patterns of the patient and generating signals corresponding to the conditions, and an information processor for receiving the signals and for controlling the output of the gas flow generator responsive to the signals. The apparatus further includes a humidifier connected to the gas flow generator for moisturizing a flow of pressurized gas provided by the gas flow generator and includes an outlet chamber including a diameter transition portion and a dissipation hole for acoustically tuning snoring sounds received by the patient.
