A nasal cannula apparatus is provided for use by patients desiring a
comfortable arrangement. The nasal cannula apparatus is particularly
suited for long-term oxygen users, for extended wear in both standing,
resting and supine positions. The nasal cannula apparatus has headgear
and retainers for holding the gas supply tubes, which are adjustable to
allow fast and easy adjustment to size. The headgear and retainers allow
the cannula tubes to be held in a position which prevents skin discomfort
and irritation, and which promotes healing of such irritation, injuries
and sores.
