Claim 13:
14. A system for delivering a pressurized flow of breathable gas to a patient, the system comprising:
a patient interface configured to contact the patient's head, the patient interface comprising a frame and a cushion supported by the frame and configured to sealingly connect the patient interface to the patient's face and form a chamber between the frame and the patient's face, an inlet port in the frame is configured to receive the pressurized flow of breathable gas;
a flow generator mounted on the patient interface, the flow generator being configured to generate the pressurized flow, capable of creating a pressure of about 2-40 cm H2O in the chamber, the patient interface and the flow generator together forming a pressurized airflow path;
a pressure sensor assembly configured to determine a pressure of pressurized gas flowing through the patient interface, the pressure sensor assembly comprising a pressure sensor located at the flow generator, a pressure port in the patient interface, and a tube connecting the patient interface to the pressure sensor at the flow generator; and
a vibration dampening and/or noise absorbing material positioned between the pressure sensor and the flow generator,
wherein the flow generator is connected to the patient interface by way of a support arm that is configured to minimize the transmission of vibrations between the patient interface and the flow generator,
wherein the pressure port and the tube connecting the pressure sensor to the pressure port are located superior to the inlet port and inferior to the support arm, and
wherein the support arm is a first support arm and the system further comprises a second support arm, the first and second support arms being positioned in a side-by-side arrangement and superior to the inlet port.
