In view of the recent evidence that "mouth-to-mouth" and other forms of expired-air resuscitation are the most effective methods of artificial ventilation, an evaluation of the Venti-Breather oral resuscitator has been performed.Studies recently performed by Gordon and co-workers,1 Elam and others,2 and Greene and co-workers3 have shown that expired-air resuscitation is the only technique assuring adequate ventilation in all cases. In view of this fact, it would be of value if the public were encouraged to accept this type of resuscitative procedure as one of the methods for adults as well as for children. METHODS OF STUDY The valve was first evaluated for durability. It was made to perform during 36 hours of continuous operation under simulated operating conditions. The inhaling side was attached to an intermittent flow source of humidified compressed gas. A test-lung was attached to the exhaling side, simulating resistance of the average
