...severe chest pains. At his bedside was a buzzer so he could summon a Secret Service agent in an emergency. Within minutes Dr. Louis Battey, an Augusta cardiologist, was at his side. He gave Eisenhower a pain-relieving drug, nitroglycerin tablets to dilate the coronary arteries, and some oxygen. The pains were intense for 30 minutes, then faded away...
...hospital, the situation seemed grim. The patient was 75 years old, his heart scarred from his earlier attack. Doctors put him under an oxygen tent and began a series of intensive tests. First results indicated it was no more than a mild attack of angina pectoris, meaning that there was an insufficient flow of blood to the heart muscle, largely as a result of hardening of the arteries. Ike himself was cheerful. The oxygen tent was removed and he even fed himself a light, low-fat breakfast, later sat up in a chair. Everyone perked up; doctors said the general...
Before McNair's discovery, there had been no evidence that advanced forms of life existed until the Cambrian period began, 600 million years ago. Many scientists believed that there was not enough oxygen in the Pre-Cambrian atmosphere to support the development of animals with specialized organs. Now the highly evolved and efficient digestive, locomotive, respiratory and nervous systems of McNair's brachiopods and worms suggest that the earth's atmosphere had an ample supply of oxygen 720 million years ago, and probably for much longer than that...
...materials have changed, the anesthesiologist's equipment has become as complex as the cockpit of a space capsule. Behind the screen that isolates the patient's head from the rest of his body, the anesthesiologist is surrounded by cylinders of oxygen and anesthetic gases, dials and valves to indicate and control their flow rates, electronic equipment to give continuous readings of the patient's pulse, breathing rate, blood pressure, and the oxygen concentration in his blood. One recent addition to the anesthesiologist's kit is an oscilloscope screen across which as many as half a dozen...
...another vital role of the anesthesiologist-where surgery is not involved or at least not scheduled. "Suppose," he said, "a patient comes in with barbiturate poisoning. All his automatic nervous system reactions, including those of his breathing center, are depressed. He may die because he is not getting enough oxygen, or he may be getting enough to keep him alive but so little as to leave him with a damaged brain. Or the respiratory depression may damage his lungs so that pneumonia and death follow. The anesthesiologist goes to work with the same equipment that he uses in surgery...
