A single use mask having an adhesive gasket is provided. The mask is of a two piece construction including a relatively hard attachment shell and a flexible gasket. The shell serves at the air chamber covering the mouth and nose of the patient as well as the point of attachment for the therapy tubing set. The flexible gasket and adhesive layer serves as the attachment means for affixing the mask to the patients face. In contrast to the masks of the prior art, the gasket is formed from a sheet of foam material.
