1. An air delivery system, comprising:
- an air flow generator to provide a pressurized flow of air;
a patient interface to provide a seal with the patient'"'"'s face in use;
an air delivery conduit to interconnect the air flow generator and the patient interface; and
a controllable vent valve to control venting from the patient interface, wherein the vent valve is controlled to maintain a substantially constant air flow in the air delivery conduit and the air flow generator.
