Abstract: A disposable mouth to mouth resuscitation device includes a one way valve for preventing the victim's breath, saliva, mucus or disease agents from contact with the resuscitator's mouth or respiratory tract. The one way valve is in a plastic body from which extends a curved airway tube for placing in the victim's mouth. At the other end of the plastic body is a flexible tube leading to a mouth piece at its opposing end, for insertion into the mouth of the resuscitator. A mouth and nose mask is connected to the plastic body, adjacent to the curved airway tube, for sealing over the nose and mouth of the victim during resuscitation. When the victim exhales, his breath and other exhaled materials are exhausted through a side port in the plastic body and into the atmosphere.
