Other researchers believe high-pressure oxygen may be useful in destroying lingering tetanus bacilli, and doctors at Maumee Vallery Hospital, Toledo, report that in some cases it is effective against oxygen-breathing microbes, including Staphylococcus aureus-"hospital staph." There is even evidence that high-pressure oxygen may help to dispel massive blood clots in the lungs, help to reverse the effects of severe heart attacks, and enhance the effectiveness of certain drugs in the treatment of certain skin cancers (melanomas...
...since May 1 this year. Once inside the pressurized chambers, Dr. Hitchcock reported, the hospital staff and patient share all the dangers of the deep-sea diver. There is nitrogen narcosis, or Cousteau's "raptures of the deep"-also known as "the martini effect"-caused by excess nitrogen; "oxygen ebullience," a kind of euphoria resulting from excess oxygen; and finally, "the bends" or "caisson disease," from too-rapid decompression...
Keeping the water out of the hamster's container was an all-but-invisible silicone rubber film. But what was truly remarkable was that the film was acting like a membrane, drawing oxygen out of the water for the hamster to breathe. Just as remarkable, the porous film was also carrying the hamster's exhaled carbon dioxide into the water...
Robb now had what amounted to an artificial membrane. Just as the lining of the lungs blocks out liquid blood but lets oxygen in and carbon dioxide out, Robb's membrane was able to filter through its gossamer skin the tiny dissolved bubbles of oxygen-rich air from water without drawing any of the liquid with it. Robb's membrane works best in a tank or stream of running water, where bubbles of oxygen are plentiful to draw on. Then the artificial membrane can operate as a gill does when it filters oxygen into a fish...
...with 35% Oxygen. General Electric says that the silicone membrane is more than a laboratory stunt, and G.E. engineers foresee half a dozen practical applications, not all of which will be water-bound. The membrane's natural preference for oxygen over most other gases (G.E. scientists, including Robb, do not yet know why) may soon result in a revolutionary unit to supply an enriched mixture of 35% oxygen for military field hospitals as well as in improved breathing systems for spacecraft and submarines. Other possibilities: space suits that cool off astronauts even as they perspire; a substitute...
