...died at 4:20 a.m. Wednesday, across the room from the recipient baby, who was being kept alive in a respirator that supplied him almost 100% oxygen. Since heart-lung machines are impractical for such small infants, the 22-man transplant team chilled the dead baby's body to retard damage to the heart. The doctors had already begun cooling the recipient baby in a water bath to 59 °F. After 40 minutes, they were ready to cut. One group excised the dead baby's heart while another excised the recipient's. In a mere...
...when the heart has "stopped cold" and there is no more respiration, the condition is often reversible-as is proved countless times every day by first-aid squads and lifeguards as well as doctors. The surgeon wants the donor's heart as fresh as possible, before lack of oxygen causes deterioration or damage-that is, within minutes of death. This has raised the specter of surgeons' becoming not only corpse snatchers but, even worse, of encouraging people to become corpses. The question remains: Where should the line be drawn between those to be resuscitated and those...
...matter. Like practically everything else in nature, the heart has fail-safe protection. It has an internal, independent, electrical "ignition systern" to trigger its beats. This system speeds up in response to outside nervous stimulation (excitement) to meet the body's resulting greater demands for blood and oxygen. But even with no external nerve connections, it responds to excitement in essentially the same fashion through the action of adrenal hormones...
Coming Downhill. In the bright sky over California's Mojave Desert, Adams unhooked from the B-52 mother ship that had carried him aloft to 45,000 ft. Then his ammonia and liquid-oxygen rocket motor ignited with 60,000 lbs. of thrust, hurtling him skyward for 80 sec. until his fuel burned out. Seconds before he glided upward to "go over the top" at his peak altitude of 261,000 ft., Adams radioed calmly to report loss of control of the X-15's pitch-and-roll dampers, twelve small rocket nozzles that guide the craft...
...suitor soon gagged on his wit as a wife. When her father took him into his brokerage office, watching the tape made him physically dizzy, and the securities he recommended for widows and orphans soon became known as "laughing stocks." When he grins into his stricken father's oxygen tent and says, "My God! You must have a strong heart to stand all this," it is a bravely joshing effort to keep mortality...
