Описание: By Richard Vann, Ph.D. Decompression sickness (DCS) may develop after a dive when very small bubbles grow as nitrogen diffuses into them from surrounding supersaturated tissue. If the bubbles remain small enough, the diver never knows they are there, and another successful dive goes into the logbook. DCS occurs if the bubbles become too large, are too numerous or are located at sensitive sites. The chances of developing DCS are normally low, but they increase with extensive bubble growth. DAN® has observed DCS incidence rates ranging from two DCS cases in 50,000 dives (one case per 25,000 dives) for Caribbean liveaboard diving to 28 DCS cases in 16,887 dives (one case per 600 dives) for cold-water wreck dives.
