ABSTRACT:
Disposable apparatus for administering oral artificial respiration to a victim which protects the rescuer administering the artificial respiration from communicable disease contact with the victim. A shield having a substantially central opening disposed therethrough is provided, this shield being contoured for positioning on the face of a human or mannikin victim with the central opening thereof being disposed over the mouth of the victim. A one way valve is operatively associated with the opening to prevent discharge of air from the victim's mouth to the rescuer. Additionally, an air deflector which projects from the shield is provided, the air deflector being positioned adjacent to the nostrils of the victim when the shield is disposed thereon so that the deflector can deflect air expelled from the nostrils in a direction away from the person giving the ventilation. The shield and air deflector along with the one-way valve totally isolate the administering individual from the victim. Resilient elements may be provided for biasing the shield away from the victim's face to permit exhalation through the victim's mouth when the rescuer removes his mouth from the shield.
