Abstract

A respiratory device is disclosed that optimizes delivery of oxygen and detection of carbon dioxide to a user through the use of a flexible lever arm and mouthpiece which may be adjusted to deliver the oxygen toward the user'"'"'s oral and nasal cavities, and detect carbon dioxide, exhaled by the user, from a separate orifice of the mouthpiece. The lever is supported by a rotatable adapter attached to a head mounted brace. The adapter can rotate through 180° for placement of the lever on either side of the user'"'"'s head. The adapter is hinged to eliminate occluding and kinking during rotation. A hose having tubular members therein delivers the gases to and from the user. The hose traverses through the lever arm and adapter, terminating at the lever arm into the mouthpiece. The mouthpiece has a plurality of ports for fluid flow. The hose terminates at the other end in gas detection and delivery equipment. The hose may be segmented or one continuous piece.
