n: a highly painful and potentially fatal condition in which air or other breathable gases come out of solution in the bloodstream and cause distress or death. So named because the bending joints of the body are most often affected. Also called decompression sickness.

n: a rapid dive with a very short bottom time to minimise decompression time.

abbr: deck decompression chamber.

n: a chamber in which excessive pressure can gradually be reduced to atmospheric pressure. It is especially equipped to help divers complete their decompression schedules and may also be used to treat diving casualties. One or more of the compartments may be installed on the deck of a work boat or barge.

n: the process of gradually lowering elevated ambient pressure to eliminate dissolved gases from a divers blood- stream and tissues.

when pressure is dropped rapidly, gas that has permeated the elastomers and some plastics may rupture the surface of a material when the gas expansion caused by the decompression is faster than the gas can pass through the substance. Most severe in weak t

n: a condition resulting from the formation of gas bubbles in a divers blood or tissues during ascent. Failure to rid tissues of the inert gas may cause a wide variety of symptoms, including pain, nausea, paralysis, unconsciousness, temporary blindness, and even death. Also called the bends.

n: a profile of ascent rates and breathing mixtures that safely reduce the pressure on a diver to atmospheric after a dive. The table shows depths, bottom times, decompression stops, and total decompression times.
