Abstract
A valved nasal cannula adapted to provide a positive pressure in the airway using the breathing of the intended user as a source of positive pressure without the need for an external source of energy and/or compressed air. The cannula is designed so as to be relatively easily insertable and retractable into and from the nasal vestibule portion of the nose of the intended user without requiring manual dexterity.
