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.

A pulmonary resuscitator for use by a single rescuer administering artificial respiration to a patient while simultaneously administering an external cardiac massage to the patient including: (a) an elongate air tube means having a first end and a second end and defining an airflow passage therethrough between said ends; (b) a mouthpiece attached to said first end of said air tube means adapted to communicate with the mouth of the rescuer; (c) patient air flow means attached to said second end of said air tube means, said air flow means providing communication between the lungs of the patient and said air tube means and including securing means to hold said air flow means to said patient so as to free the hands of a rescuer; (d) bipositional valve means positioned within said air tube means intermediate said first and second ends and near said second end, said valve means including: (1) a valve body having an inner chamber therein, said chamber communicating through said air tube means with said patient air flow means; (2) a passageway interconnecting said chamber with said air tube means and said mouthpiece and defining an opening leading into said chamber; (3) an exhaust port through said valve body and communicating said chamber with ambient air surrounding said valve body; (4) a butterfly flap positioned within said valve body and including an outer surface and an inner surface; said flap being alternatively positionable between a first position, wherein said flap outer surface sealably abuts against said passageway opening and blocks air flow from said chamber to said passageway such that air exhaled from said patient is directed through said exhaust port and prevented from passing through said valve body passageway to said rescuer, and a second position, wherein said flap inner surface sealably abuts against said exhaust port such that air exhaled by said rescuer passes through said chamber of said air tube means to the lungs of said patient and is prevented from exiting said exhaust port; (5) hinge means connecting said flap to said valve body and maintaining said flap within the air flow stream passing through said valve body such that reciprocal breathing motivates said flap to rotate between said first and second positions; and (6) positional means for maintaining said flap within the air flow stream passing through said valve body such that a directional change in the air flow stream motivates said flap to rotate from one of said flap positions to the other of said flap position; and (e) a compressed oxygen tap adapted to be connected to a compressed oxygen source and communicating freely and without restriction with said air flow passage of said air tube means to provide continuous flow from said compressed oxygen source to said airflow passage; said tap being located near said valve means and said tube means being valveless between said tap and said mouthpiece so as to allow continuous filling of said tube means through said tap; said air tube means providing a reservoir for said oxygen between said mouthpiece and said tap; and said air tube means providing substantially unrestricted and free flow of said oxygen between said mouthpiece and said tap.
