what exactly happens in the first situation, that results in this condition?
During ascent, the ambient pressure is reduced and at some stage the inert gases dissolved in any given tissue will be at a higher concentration than the equilibrium state and when there is a pressure reduction, excess gas may form bubbles, which may lead to this condition.
Decompression (diving)
During ascent, the ambient pressure is reduced
what happens when a diver gets the bends It forms bubbles inside any part of the body and its effects may vary from joint pain and rashes to paralysis and death. what is the medical term for this condition? Decompression sickness what are some factors that cause it? Underwater diving decompression, caisson, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft.

Decompression (diving) [SEP] Introduction
When a diver descends in the water the hydrostatic pressure, and therefore the ambient pressure, rises. Because breathing gas is supplied at ambient pressure, some of this gas dissolves into the diver's blood and is transferred by the blood to other tissues. Inert gas such as nitrogen or helium continues to be taken up until the gas dissolved in the diver is in a state of equilibrium with the breathing gas in the diver's lungs, at which point the diver is "saturated" for that depth and breathing mixture, or the depth, and therefore the pressure, is changed. During ascent, the ambient pressure is reduced, and at some stage the inert gases dissolved in any given tissue will be at a higher concentration than the equilibrium state and start to diffuse out again.
