Abstract
A nasal mask for applying pressurized gas to a user's respiratory system. The mask includes an inflatable seal which is at least partially filled with a soft open cell foam. The seal includes a manual pump and a pressure release valve for inflating and deflating the seal. The mask includes an brow bar which is connected through a bridge to the mask body. The bridge can be adjusted to position the brow bar against the user's forehead for supporting an upper portion of the mask. Headgear for attaching the mask to the user is attached to the brow bar and is looped over a prong at a lower portion of the mask for securing the lower portion of the mask to the user. The mask can be easily removed from the patient while leaving the headgear and brow bar attached to the user.
