ABSTRACT:
A respiration mask (10) including a shield (12) and a valve (14). The valve preferably includes two unidirectional elements (20) and (22) that allow air to flow therethrough, while limiting the reverse flow of contaminants. In use, the mask (10) is placed over a victim's face, with the shield covering the victim's face and the valve in the victim's mouth. A rescuer than performs mouth-to-mouth respiration in the standard fashion, with the shield and valve protecting the rescuer from victim contaminants.
