A nasal positive airway pressure device is provided having a plenum chamber, a pair of nasal delivery members, and a variable orifice venting aperture member. The variable orifice venting aperture member preferably is mounted to the plenum chamber, but may be mounted at other locations in communication with the nasal delivery members. The variable orifice vent aperture member expands under increased pressure, e.g., during exhalation, and contracts to its original diameter at lower pressures, e.g., during inhalation, to provide variable venting capacity during positive airway pressure treatment.
