ABSTRACT:
An apparatus includes a respiratory mask and a seal. The mask is adapted to encircle the mouth of a user and convey gasses to and from the mouth of a user through a port therein. The seal is a hydrogel seal that is relatively sticky and resilient so as to provide a tight seal between the mask and the user during usage thereof.
