1. A mask for use in a patient interface device for delivering a flow of breathing gas to an airway of a patient, the mask comprising:
a first portion formed from a pliable material, the first portion having at least one aperture defined therethrough;
a cavity defined at least in-part by the first portion and accessible via a port defined in the mask, the cavity being structured to receive the flow of breathing gas provided to the port and to communicate the flow to the airway of the patient; and
a member formed from another pliable material, the member disposed in the cavity and coupled to the first portion, the member movable from:
a first position in which the member is directly sealingly engaged with the pliable material of the first portion about a periphery of the at least one aperture and is structured to prevent passage of the breathing gas from the cavity through the at least one aperture, and
a second position in which at least a portion of the member is spaced from the periphery of the at least one aperture and is structured to allow passage of a gas external to the cavity into the cavity through the at least one aperture,
wherein the member comprises a sheet-like pliable member,
wherein the at least one aperture comprises a plurality of apertures, and
wherein the sheet-like pliable member includes:
a first portion movable from a first position in which the first portion is sealingly engaged about a periphery of a first aperture of the plurality of apertures thus preventing passage of a fluid through the first aperture and a second position in which at least a portion of the first portion is spaced from the periphery of the first aperture such that the fluid is able to pass through the first aperture; and
a second portion movable independently from a first position in which the second portion is sealingly engaged about a periphery of a second aperture of the plurality of apertures thus preventing passage of the fluid through the second aperture and a second position in which at least a portion of the second portion is spaced from the periphery of the second aperture such that the fluid is able to pass through the second aperture.
