Abstract

A nasal cannula (10) for delivering air to a patient's nare (14). Two delivery tubes (20) and (21) are provided to supply air to a pair of nasal inserts (12) and (13) each of which conform to the shape of the nare (14). Properly placed bleed ports (16) and (17) reduce noise and reduce carbon dioxide retained in the system. The cannula (10) is positioned on the face with the aid of a strap system (18).
