Zusammenfassung:A patient interface includes a cushion assembly adapted to form a seal around the patient's nose and/or mouth and a gas washout vent configured to allow a flow of patient exhaled CO2 to an exterior of the patient interface to minimise rebreathing of exhaled CO2 by the patient. The cushion assembly defines a plenum chamber pressurised at a pressure above ambient pressure in use. At least one volume reducing member is provided within the plenum chamber to reduce an effective internal volume of the plenum chamber. The at least one volume reducing member is arranged to separate a main volume of the plenum chamber for delivery of the therapy pressure from deadspace volume provided at least superior the entrance to the patient's nasal passages. The main volume is adapted to be in direct fluid communication with the patient's nose and/or mouth and the vent.
