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.
