An integrally molded ventilation interface (1300) includes a hollow bellows-like structure (1320) and two nasal prongs (1310) extending from a top surface of the bellows. A pair of headgear strap flanges can also be molded integrally with the ventilation interface. The nasal prongs provide a first sealing interface between an outer surface of the nasal prongs and an inner surface of the patients nares. The bellows provides a second sealing interface between a top surface of the bellows-like structure and a bottom surface of a patients nose. The headgear strap flanges provide a third sealing interface between the ventilation interface and a mustache region of the patients face as well as a bottom surface of the patients nose.
