Abstract

A multi-chamber mask includes a shell and a partition. The shell is adapted to cover portions of a user's face including the mouth and at least portions of the nose including the nostrils, the shell adapted to contact the face surrounding the covered portions of the face to substantially prevent gas from escaping between the shell and the contacted portions of the user's face, and the shell is adapted to couple to a gas supply source. The partition is coupled to the shell and cooperates with the shell to define a first chamber and a second chamber, the first chamber adapted to be positioned proximate the user's nose to direct inflow of gas from the gas supply source to the user's nasal passages, the second chamber adapted to be positioned proximate the user's mouth, the partition adapted to restrict flow of gas between the first and the second chamber.
