Mask and mask-mounted flow generator system

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 detect a gas pressure within the patient interface, the pressure sensor assembly comprising a pressure sensor located at the flow generator and a conduit that pneumatically connects an interior of the patient interface to the pressure sensor;
• 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 sensor is positioned 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.
