Abstract

A pulmonary resuscitating device designed for single time use and for use with administering cardiopulmonary resuscitation to a heart failure patient. The device includes an endotracheal tube for insertion in the patient's trachea, a mouthpiece for a rescuer, and an air passageway therebetween. Included in the air passageway is a two-way valve which allows exhaled air from a rescuer to pass to the patient's lungs while diverting the patient's exhaled air to the atmosphere. An oxygen tap is provided between the rescuer's mouthpiece and the valve to allow oxygen enriched air to be administered to the patient.
