...main trouble with deep diving is that when the diver breathes ordinary air under too much pressure, nitrogen dissolves in his blood and tissues, causing dizziness and other kinds of trouble. Below about 240 ft., the air pumped down to the diver is replaced by a mixture of oxygen and helium. The helium penetrates the tissues, but does not have the bad effects of nitrogen. When the diver comes to the surface, however, he must be decompressed slowly lest bubbles of helium give him painful, sometimes fatal "bends...
When Boatswain Wookey was lowered into the water, he was breathing ordinary air, but when he reached 40 ft., the pump began supplying a mixture of oxygen (8.5 parts) and helium (91.5 parts). Going down was comparatively easy. In spite of the 273 Ibs. of pressure on every square inch of his body (39,312 Ibs. per sq. ft.), he felt fine. "I felt no more effect from the helium," he says, "than I would from nitrogen at shallow depth. My mind was clear. I did the job I was sent down to do." His token job, to prove that...
...breathes a small proportion of all the molecules of nitrogen and oxygen are ionized by cosmic rays-they become positive ions if they lose an electron, negative ions if they gain one. Philadelphia researchers have found that almost two-thirds of hay fever victims won quick relief in air that was heavily negative-ionized, snuffled and sneezed far more in air that was artificially positive-ionized. As a result, Philco Corp. plans to market a negative-ionizing air conditioner. ¶Automobile-accident victims often report "brain concussions" and are admitted to hospitals for study, but in 30% of cases studied...
...early morning hours from 4 to 6 a.m.? My own research has shown that these thoughts coincide with a fall in the blood sugar level to the lowest point of the day, an abnormal physiologic state known as hypoglycemia. During this state, the entire body suffers a reduced oxygen consumption, and the organ most vulnerable is the brain. It is caused by faulty diet, namely, eating too much sugar (and foods containing sugar) and starchy foods during the night and day preceding...
...Santa Monica Hospital how much barbiturate he had taken, and the empty pill bottle told what kind. It was too late for stomach pumping to do any good. He was promptly put on the standard treatment for such cases: an injection of picrotoxin to stimulate the nervous system, and oxygen by mask...
