Beschreibung
Zusammenfassung:	An interface device comprises a cushion and a shell coupled thereto which together define an interior space with the face of a user. The shell includes an inlet port structured to have a conduit carrying a flow of treatment gas to the interior space selectively coupled thereto and a first aperture structured to allow the passage of ambient air into the interior space. A first sealing member is operatively coupled to the shell and is positioned such that the first sealing member is movable between a first state in which the first sealing member substantially seals the first aperture, and a second state wherein the sealing member does not substantially seal the first aperture. The first sealing member moves between the first state and the second state responsive to breathing of the patient.
