Abstract

An apparatus for delivering a flow of breathable gas to a patient for the treatment of Sleep Disordered Breathing (SDB) that is less obtrusive includes a nasal cannula, cannulae (2a, 2b), prongs, or pillows and may be sealed or unsealed with the nares of the patient in use. The cannula, pillows or prongs may be positioned on the face of the patient by a headgear (6). The cannula, pillows or prongs may be smaller, lighter, and/or less visible than other nasal cannula, cannulae, pillows or prongs and may therefore be less obtrusive to the patient.
