An integrated nasal mask is adapted for delivering gas to a patient and comprisesa mask body and a pair of elongate nostril-engaging stems. The mask body is generallytriangularly shaped and includes a nasal opening sized and configured to substantiallyenvelope a patient's nose. The nasal opening opens to a nasal cavity. Thenostril-engaging stems extend outwardly from the nasal cavity. Each one of thestems defines a fluid passageway for delivering gas to the patient's noseand for allowing discharge of exhalation gasses during the exhalation phaseof the breathing cycle.
