Like a Sub. Only a mile away at Westminster Hospital, high-pressure oxygen is producing impressive results for Dr. Richard Ashfield's coronary patients. To administer oxygen under pressure, Dr. Ashfield helped to design a device that looks like a minature submarine with a bubble top. Inside it, the patient lies on a foam-rubber bed or can lean half upright against a back rest. The lid is tightly shut by a series of strong sealing locks around...
...Ashfield reasons that victims of severe heart attacks not only feel and appear breathless-they are actually oxygen-starved because neither heart nor lungs are working efficiently. For his tests he has chosen only patients who have had severe, potentially fatal heart attacks. He puts them in the chamber for a minimum of four days (one man stayed in for ten days). The patient breathes pure oxygen under pressure for two hours; then the lid is opened, and he breathes ordinary air for one hour. This cycle is repeated around the clock. Of Ashfield's first 40 patients, only...
...from all but radio contact with other human beings, confined to a 40-ft.-long chamber and breathing the same limited supply of oxygen over and over, four California college students might as well be in far-off space. And that is the idea. Ever since they were sealed up in a white steel cylinder in an outbuilding behind the McDonnell Douglas Corp.'s Santa Monica plant on Feb. 19, the students have been testing a life-support system designed for future orbital missions t hat could last for 60 days or longer...
...minimize the amount of oxygen necessary to maintain the two-gas atmosphere (44% oxygen, 56% nitrogen) that the student crew breathes, the simulated spacecraft is equipped with a concentrator that pulls exhaled carbon dioxide out of the air. The carbon dioxide is combined in a catalytic reactor with hydrogen and converted into water and methane. An electrolysis system then decomposes the water into oxygen-for breathing-and hydrogen that is used to feed the catalyti c reactor. Reluctant to waste even the squeal of this chemical pig, McDonnell Doug las engineers are working on spacecraft thrusters that can be powered...
Even lung disease, including cancer, may be reflected in the hands, said Dr. Silverman. Emphysema, the currently common disease marked by inadequate oxygen intake at the lungs' surface, may produce clubbing of the fingers. The type of cancer that occurs most commonly in long-term male cigarette smokers may eventually lead to acutely painful clubbing of the fingers and equally painful enlargement of the toe joints...
