Minneapolis surgeons had been getting good results with their "cross-circulation technique" for delicate surgery inside the heart-using another human being's heart and lungs to take the load off the patient's while they operated (TIME, May 10). But it was a tricky business, and they would have liked to cut out the danger to a second human being. Why not a mechanical heart and lungs, which several research teams have tried? For one thing, the Minneapolis doctors reasoned, strange things can happen to human blood in a mechanical oxygenating system; it may undergo mysterious changes...
...inefficiently back and forth. The University of Minnesota's team of heart repairmen, headed by Dr. Clarence Walton Lillehei, needed a "dry field" (the heart drained of blood) if they were to operate successfully. A Toronto-born colleague, Dr. Gilbert Campbell, 31, offered them the dog's lung to attain this. (He had already used lungs in 100 experimental operations with animals...
...hour before Calvin was to be ready, surgeons anesthetized a big dog (what breed, if any, is a secret) and removed an entire lung. The animal was then painlessly put to death with more anesthetic...

It is not likely that she would be. Compressed air, not oxygen, is used with an Aqua-Lung, and oxygen breathed at depths of more than about 35 ft. becomes highly toxic to the human body, resulting in convulsions, blackout, and eventully death...
