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
Scuba diving components of the diver's breathing gas accumulate in the tissues during exposure to elevated pressure during a dive, and must be eliminated during the ascent to avoid the formation of symptomatic bubbles in tissues where the concentration is too high for the gas to remain in solution. This process is called decompression. Most recreational and professional scuba divers avoid obligatory decompression stops by following a dive profile which only requires a limited rate of ascent for decompression, but will commonly also do an optional short shallow decompression stop known as a safety stop to further reduce risk before surfacing.
