摘要：
A patient interface can have a frame supporting a sealing member. Various features of the sealing member can improve comfort and sealing performance in the context of forming seals with the nares of a user, as well as contact with other facial surfaces. The sealing member can include convex portions, concave portions and thickness variations for providing various sealing, comfort, and deformability effects.
