...researchers were well aware that any land animal, including man, suffers irreparable brain damage if his supply of circulating oxygen is cut off for more than four or five minutes, and drowns in a few minutes more. But they also knew that any one of several diving birds (loons, grebes, cormorants and "sea ducks") can endure immersion for more than ten minutes. The warmblooded seal can endure under water for more than 20 minutes, and the equally warm-blooded whale can last for an hour, perhaps even two. Scholander's odd experiments were carefully designed to discover...
...head and another smaller wound-from the second of the three shots-in his throat. Clark and eight other doctors worked over him for 40 minutes, but the President was already as dead as though he had fallen on a battlefield in mortal combat. The doctors gave him oxygen, anesthesia, performed a tracheotomy to help breathing; they fed him fluids, gave him blood transfusions, attached an electrocardiograph to record his heartbeat...
...victim of cystic fibrosis, almost invariably a child because the disease is usually fatal before adulthood, has an inherited enzyme defect that damages the oxygen-exchange cells in his lungs and reduces the elasticity of the lung walls. He does not breathe enough air in, nor let enough out. His windpipe and lungs become clogged with thick viscid mucus. The trick is to loosen and thin this mucus...
Useless Pumping. In transposition, placement of the heart's outflow pipes is reversed. The aorta, the great artery designed to supply oxygenated blood to the entire body, arises from the right lower chamber (ventricle) of the heart instead of from the left. As a result, it carries used blood back into circulation. The pulmonary artery, designed to carry used blood to the lungs for oxygenation, arises from the left ventricle instead of from the right; as a result, oxygen-enriched blood is pumped uselessly back and forth between lungs and heart...
...industry has averaged more than $1 billion a year to expand, modernize and automate; it plans to invest $1.2 billion this year and $1.5 billion next. Last week National Steel opened a $100 million hot-strip mill near Detroit, and in Kentucky, Armco Steel brought in two new oxygen-process steel furnaces and started pouring iron from the largest blast furnace in the Western world (daily capacity: 3,340 tons). The payoff from such new facilities as U.S. Steel's five basic oxygen furnaces now building in Duquesne, Pa., and Gary, Ind., will come later...
