Decompression sickness is treated with recompression in a chamber to 60 FSW or deeper associated with hyperbaric oxygen breathing. The bubbles in the body may form in the venous blood, musculoskeletal system or other body tissues; decompression sickness is the clinical condition that results. http://www.scuba-doc.com/DCSPartI.html   (4731 words)      Decompression Sickness (The Bends) Rashes and itching by itself may be transient and does not require decompression, however marbleization (cutis marmorata) or molting of the skin, should be treated by recompression. As soon as it is believed that the victim has decompression sickness positive pressure oxygen (100%) must be given. Symptoms that develop after 24 hours are probably not the result of decompression sickness. http://www.rescuediver.org/med/bends.htm   (2981 words)      Spinal Cord Decompression Sickness All patients underwent MR examination of the spinal cord (0.5-T, surface coil) and were treated with therapeutic hyperbaric recompressions and auxiliary therapy. Hyperbaric oxygen therapy provided in specially designed pressure chambers is currently the treatment of choice for decompression sickness. This exhibit discuss the value of MR imaging in the detection of pathologic changes of spinal cord decompression sickness, that were previously undetectable by other neuroimaging methods. http://mbox.unipa.it/~radpa/l1/dcs.html   (680 words)      Decompression sickness - Wikipedia, the free encyclopedia The physiologist John Haldane studied this problem in the early 20th century, eventually devising the method of staged, gradual decompression, whereby the pressure on the diver is released slowly enough that the nitrogen comes gradually out of solution without leading to DCS. Even when the change in pressure causes no immediate symptoms, rapid pressure change can cause permanent bone injury called dysbaric osteonecrosis (DON) "bone cell death from bad pressure".

J.S. Haldane in the early 1900's discovered if a person halved their pressure they could have bubble formation. The diver is kept well-informed as to how much time they have left at any depth before a danger of decompression sickness becomes a real threat. For years this author dove with the mistaken notion that if we surfaced properly (then 25'/minute, now 60'/minute), and did not exceed the time allowed on the USN Decompression Table at various depths in order to avoid a ceiling, we would avoid having those horrible nitrogen bubbles form creating decompression sickness. http://www.deep-six.com/page78.htm   (4674 words)      Decompression Sickness: Can exercise before diving prevent illness?, March 29, 2004 This finding may form the basis for a novel approach for preventing serious decompression sickness.

The state of the body that describes the probability of dissolved nitrogen coming out of solution to produce DCS is referred to as "decompression stress." It is thought by many researchers that disordering of the microcirculation can occur in some situations such as multiple or deep dives, thus interfering with predictable off-gassing of nitrogen.
