Abstract
Abstract A shield for use in mouth-to-mouth or mouth-to-nose resuscitation. The shield is constructed of a one piece sheet of thin flexible material capable of assuming complimentary sealing relationship over a patient's face and includes dimensions sufficient to cover the face from ear-to-ear and from the bridge of the nose to the bottom of the chin. The shield includes a mouth opening located substantially centrally thereof and adapted to fit over a patient's mouth to permit air to be blown therethrough into the patient's lungs in mouth-to-mouth resuscitation. A lip flap can be optionally provided around the periphery of the mouth opening and a second opening can be provided in spaced relationship with the mouth opening for use in mouth-to-nose resuscitation.
