Abstract
A gas delivery apparatus includes a nasal airway having a gas passage therein for insertion into the nose, a swivel connected to the nasal airway and tubing connected to the swivel. The swivel has a gas passage therein that communicates with the gas passage with the nasal airway. Further, the tubing has a proximal portion connected to the swivel so as to be in fluid communication with the gas passage of the swivel. The tubing bends so that an angle is formed between the distal portion of the tubing and the proximal portion of the tubing. The nasal airway preferably includes a nasal vestibular portion that is adapted to fit in a nasal vestibule, a connection portion extending from the nasal vestibular portion and the gas passage that extends through the connection portion and through the nasal vestibular portion. The nasal vestibular portion flares outwardly with respect to the connection part.
