Decompression (diving) If the concentration gets too high, it may reach a stage where bubble formation can occur in the supersaturated tissues. When the pressure of gases in a bubble exceed the combined external pressures of ambient pressure and the surface tension of the bubble-liquid interface, the bubbles grow, and this growth can damage tissue. If the dissolved inert gases come out of solution within the tissues of the body and form bubbles, they may cause the condition known as decompression sickness, or DCS, also known as divers' disease, the bends or caisson disease. However, not all bubbles result in symptoms, and
Ratio decompression by the body from breathing gases under pressure has never been definitively established, particularly in relation to the formation of bubbles in the body's tissues, and a number of different algorithms have been developed over the years, based on simplified hypotheses of gas transport and absorption in body tissues, modified to fit empirical data, to predict the rate of off-gassing to reduce the risk of decompression sickness in divers to an acceptable level. However, these models do not describe the individual physiology of the diver accurately: divers have been known to suffer symptomatic decompression sickness whilst diving within the limits
