ABSTRACT A nasal adaptor device and seal for delivering gases under pressure to the nasal airway of an individual including an aerodynamically contoured manifold to receive gases from an inlet and to divide the gases for flow to a pair of flange members, preferably having a nonspherical curved "egg-shaped" surface, which members are complementary to the nares of an individual without cannulating the nares to provide a seal to withstand positive pressure of gases to be distributed to the nasal airways. The devices and nares seals of this invention are especially useful in treatment of obstructive sleep apnea and in ventilation of individuals for whom positive pressure ventilation is indicated.
