A disease usually caused by staying for some time in an environment of high pressure, such as caissons, scuba diving bells, etc. It's characterized by neuralgic aches and paralytic symptoms. It is due to the production of bubbles of fuel, typically nitrogen, from body fluids into the blood and tissues, when one, having experienced an environment with a high air pressure, moves to a lower stress environment too quickly for the extra dissolved gases to be released through typical respiration. It could be fatal, but could be reversed or relieved by returning the affected individual to a high air stress, after which gradually reducing pressure to allow the gases becoming circulated from the human anatomy fluids. Its a danger well-known to scuba divers. Furthermore called the bends and decompression nausea. It can be avoided in divers by a slow come back to typical stress, or by using a breathing blend of oxygen combined with a gas having low solubility in water, such helium.
