In 1949-50, he evaluated the various methods of artificial ventilation with arm maneuvers and chest compressions used at the time, and found them to be of marginal benefit.

Dr. James Elam published the first scientific paper (1956) showing that oxygen could be delivered into a non-breathing patient's lungs from a rescuer's exhaled breath, using a tube.

Dr. Peter Safar followed with a simple gadget-free method, exhaling air directly into the mouth of a non-breathing person (1957). At the University of Southern California, quickly repeated the experiments in children.

Within a year, these three doctors convinced the world to change artificial breathing methods.
