Abstract
A nasal cannula can be 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 can have angled ends such that, in use, gases flowing through the prongs are directed to the user's nasal passages. The nasal cannula body can be partially swiveling and preferably has a ball joint connector. The nasal cannula can have at least one flared end prong that preferably seals within a patient's nare.
