Abstract
An integrated nasal mask is adapted for delivering gas to a patient and comprises a mask body and a pair of elongate nostril-engaging stems. The mask body is generally triangularly shaped and includes a nasal opening sized and configured to substantially envelope a patient's nose. The nasal opening opens to a nasal cavity. The nostril-engaging stems extend outwardly from the nasal cavity. Each one of the stems defines a fluid passageway for delivering gas to the patient's nose and for allowing discharge of exhalation gasses during the exhalation phase of the breathing cycle.
