Abstract
A mask adapted to be placed over the mouth of a subject during mouth-to-mouth resuscitation includes a fibrous, central, air-permeable filter portion, a transparent portion surrounding the filter portion, and a stiffening portion surrounding the transparent portion, so that the mask may be grasped by the stiffening portion and visually adjusted through the transparent portion to locate the filter portion over the mouth of the subject.
