Abstract
In one embodiment, a nasal cannula is shaped to fit within a user'"'"'s nares, where the nasal cannula includes at least one prong allowing high flow delivery of humidified gases and creates positive airway pressure in the patient'"'"'s airway. The prongs have angled ends such that, in use, gases flowing through the prongs are directed to the user'"'"'s nasal passages. The nasal cannula body is partially swivelling and preferably has a ball joint connector. In another embodiment the nasal cannula may have at least one flared end prong that preferably seals within a patient'"'"'s nare.
