...deep-sea divers. Now, with the craze for skindiving, with Aqua-Lungs, snorkels and similar gadgets sold in the corner store, civilian doctors are daily confronted with unfamiliar problems. In the New England Journal of Medicine, one of the Navy's top underwater medicinemen, Lieut. Edward H. Lanphier, offers a primer. Dr. Lanphier, of the Navy's Experimental Diving Unit in Washington, D.C., is principally concerned about amateurs who use "scuba"-the skindiver's abbreviation for self-contained underwater breathing apparatus...
...environment as a man dives deeper is the increase in pressure: equivalent to a whole atmosphere (15 lb. per sq. in.) for every 33 ft. of salt water (34 ft. of fresh water) through which he descends. Much nonsense has been written about this "tremendous crushing force," Dr. Lanphier notes, but "the body as a whole, being made up of solids and fluids, is no more likely to be crushed than a bucket of water lowered into the depths." Damage can occur only when there is an unequalized difference of pressure-and that means where there...
...diver who holds his breath while ascending is in a far worse plight: instead of a low-pressure pocket, a high-pressure pocket forms in his lungs, which may burst as a result. The diver is, says Dr. Lanphier, "immediately a candidate for one of the most serious of all diving accidents: air embolism." Apart from the danger of a lung bursting, the abnormal pressure can force air bubbles through the pulmonary veins and into the heart. The bubbles usually travel to the brain, causing convulsions and unconsciousness, and unless the victim is treated promptly by recompression, he is almost...
...Lanphier prefers prevention to cure: by Navy standards, skindivers should not spend more than two hours under water at 40 ft., not more than 30 min. at 90 ft., and not more than 15 min. at 130 ft. The rate of ascent should not exceed 60 ft. a minute...
