decompression
(gcide) | decompression \decompression\ n.
1. the process of experiencing decompression; the act or
process of relieving or reducing pressure.
Syn: decompressing.
[WordNet 1.5 +PJC]
2. the reduction of atmospheric pressure experienced by
divers rising from deep water to the surface, thus
reducing the concentration of dissolved atmospheric gases
in the blood; -- especially applied to a gradual reduction
of such pressure.
[PJC]
3. the process, analogous to sense 2, undergone by divers in
a decompression chamber, in which an artificially high
atmospheric pressure is gradually lowered to normal
pressure.
[PJC]
4. a return to a normal, more relaxed state after a period of
intense stress, psychological pressure, or urgent
activity; -- of people.
[PJC]
5. (Computers) the process of converting digitally encoded
data from a more compact (compressed) form to its
original, larger size.
Note: The process of compression and decompression may
completely recover all of the original data (called
lossless compression), or may lose some of the original
data in order to achieve higher degress of compression
(lossy compression). The latter is used especially with
images or video data, which may be of very large size
relative to text, and for which small changes may be
imperceptible to the human eye. The JPEG data
compression format is a lossy format.

decompression sickness
(gcide) | Caisson disease \Cais"son dis*ease"\ (Med.)
A disease frequently induced by remaining for some time in an
atmosphere of high pressure, as in caissons, diving bells,
etc. It is characterized by neuralgic pains and paralytic
symptoms. It is caused by the release of bubbles of gas,
usually nitrogen, from bodily fluids into the blood and
tissues, when a person, having been in an environment with
high air pressure, moves to a lower pressure environment too
rapidly for the excess dissolved gases to be released through
normal breathing. It may be fatal, but can be reversed or
alleviated by returning the affected person to a high air
pressure, and then gradually decreasing the pressure to allow
the gases to be released from the body fluids. It is a danger
well known to divers. It is also called the bends and
decompression sickness. It can be prevented in divers by a
slow return to normal pressure, or by using a breathing
mixture of oxygen combined with a gas having low solubility
in water, such as helium.
