...bring about this painless state, or analgesia, which involves the entire body,* Dr. Artusio puts patients through all the usual sequence of anesthetics (barbiturates, thiopental sodium, nitrous oxide, oxygen, ether) until they lose consciousness. Then he gives more oxygen and less ether, so that they edge back across the threshold into consciousness, and holds them at this level. Edna's case, filmed in color by E. R. Squibb & Sons for hospitals and professional groups, was typical of 120 mitral valve repairs on which Drs. Glenn and Artusio have worked-enough, they feel, to establish that ether analgesia is just...
...using themselves as guinea pigs for experiments in low-pressure chambers, on high-speed centrifuges and rocket-powered sleds. They are toiling up the Andes to find out how Peruvian Indians stand the strain of high altitude, breathing radioactive gases, and sweating in 122° chambers on low oxygen...
...field of vision narrow's, so the armed forces require all flyers to breathe extra oxygen above 10,000 ft. in daylight (above 5,000 in darkness). Up to 15,000 ft., most flyers remain conscious without oxygen, but their working efficiency is reduced. After 15 minutes to an hour at approximately 18,000 ft., nearly all (unless acclimatized like Alpinists) lose consciousness. But before a man does so, he may have strange delusions. Classic example: a reconnaissance pilot in the western Pacific in World War II refused to bother with oxygen and thought he was taking magnificently daring...
...room for two hours. The fat men kept their internal body temperatures normal, although their skin temperatures dropped. The thin men maintained higher skin readings, partly by drawing on the body's internal heat supply, partly by shivering more. The shivering was accompanied by increased oxygen consumption, as the thin men burned more food to keep warm...
...hypersonic tunnel is a vacuum chamber at one end and a gas-charged cannon at the other. At the beginning of each test, a strong-walled tube six feet long and three inches in diameter is charged at high pressure with an explosive mixture of hydrogen, oxygen and helium. When the gas is detonated (with a bang like a 37 mm. gun), it ruptures a copper diaphragm. A blast of hot gases preceded by a shockwave races down a long evacuated tube. Pushed by pressure behind and pulled by the vacuum ahead, it expands through two nozzles...
