...Richard V. Ebert told a meeting of the New York Heart Association, emphysema is a more or less permanent inflation of the lungs resulting from the loss of elasticity in their deepest recesses. There the tiny alveoli, or gas-exchange cells, give up carbon dioxide and take in oxygen. Clustered around small arteries, they are so numerous that they create a huge area for gas exchange-about 85 sq. yds. in the average adult...
Squeeze the Heart. But doctors still wanted something more automatic and reliable. Working with engineers of Massachusetts' Brunswick Manufacturing Co., they devised the Thumper, which is basically a small (1½ in. by 3 in.) pneumatic plunger strapped to the chest (see cut). Powered entirely by compressed oxygen (small tanks in portable units, bigger ones in hospitals), the HLR supplies a puff of oxygen twelve times a minute through a face mask, while the plunger, which replaces the rescuer's hands, bounces up and down on the victim's breastbone 60 times a minute. On the downstroke...
...Unknown in nature, these are similar to the innumerable "organic" (carbon-containing) compounds, but have the central chain of carbon atoms replaced by a silicon-oxygen chain. Common sand consists mainly of quartz, which is silicon dioxide...
...adults, oxygen deprivation causes irreversible brain damage within about four minutes. Nature's wisdom gives the newborn an extra ten or 15 minutes...
Oddly enough, the film is most absorbing when Cousteau lets his camera or his commentary dwell on the extraordinary detail of his men's day-to-day existence. In the heavy air, laden with double the normal amount of oxygen, cuts and abrasions heal overnight. Beards almost stop growing. In the 86-ft. Deep Cabin, the male larynx, in reaction to helium, produces shrill chipmunk sounds. The men listen to music, keep house, play chess, pamper a parrot, and begin to feel strangely detached from events in the surface world. Jewel-bright sea creatures hover outside the glass windows...
