ABSTRACT:
A mask (10) for supplying gas under pressure to the nasal airway of a human includes a manifold (30) including means (36) for connection to a gas supply means, a gas supply element or elements (26) for providing said gas to the nasal airway without pressurising the exterior of the nose and a flexible strap (12) formed from an elastomeric material for securing the manifold (30) in position. The strap (12) extends either side of the manifold (30) and is shaped to generally conform with the shape of the upper lip and adjacent cheek area to act as a distributed anchor means for the mask (10).
