A nasal continuous positive airway pressure apparatus includes a pair of cannula each having an inflatable cuff to position the cannulae within the nares of a patient. The cannulae are connected to a source of positive air pressure to provide continuous positive nasal airway pressure. The cuffs may be inflated by providing cuff apertures in the cannula so that the positive airway pressure during inhalation and exhalation maintain the cuffs inflated and the cannulae positioned within the nares during treatment. Alternatively, the cuffs may be separately inflated. The apparatus includes an inflatable air strap harness to position and hold the nasal cannulae device relative to the patient\s head. The inflatable air strap harness is soft and flexible and comfortable for the patient to wear. The air strap is inflated and secured, such as with a hook and loop belt, surrounding the patient\s head with the cannulae inserted into the patient\s nares. The cuffs are inflated and air pressure applied to the conduit to administer treatment. The air strap is inflated by the same air pressure being applied to the patient\s airway or is inflated by a separate source such as a hand pump.

A nasal airway pressure device comprising: a pair of naris cannulae made of a substantially rigid material, each said cannulae configurated and dimensioned for insertion into the naris of a patient and having a lumen; a pair of inflatable cuffs, each said cuff surrounding at least a portion of one of said cannulae, each said cuff configured and dimensioned to inflate and come into contact with the interior, naris defining walls of a patient\s nose so as to maintain the position of a portion of said cannulae within a naris of a patient and establish a substantially air-tight seal between said cannular portion and the naris, a second portion of said cannulae configurated and dimensioned to extend out of the naris; at least one aperture providing gaseous communication between said cannulae lumen and said inflatable cuff for inflating said inflatable cuffs; a conduit in communication with said lumen at said second cannular portion for supplying positive gas pressure to said lumen, said positive gas pressure inflating said cuffs through said aperture during inhalation by the patient so that said cuffs engage the interior walls of the patient\s naris in order to maintain the position of said cannulae in the naris and establish a substantially air-tight seal between said cannulae and the naris, said cuffs being inflated during exhalation of the patient by exhaled gas expelled through said cannulae in communication with said aperture, said conduit including at least one vent hole for relieving excess pressure during exhalation.
