Abstract
A resuscitation mask has a base member with an inflatable bladder about its periphery which will rapidly and effectively seal against the face of the patient upon initial flow of air into the mask from the rescuer. A delivery member causes air to flow to the bladder to effect the inflation and then a valve member precludes further inflation. A one-way valve and filter in the conduit from the delivery member to the base member precludes flow of air and body fluids from the patient to the mouthpiece, and diverts exhaled air to the atmosphere about the mask.
