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
Professional diving rarely use scuba equipment. Scuba equipment is not commonly used in civilian commercial diving, but is often employed by scientific, media and military divers, sometimes as specialized equipment such as rebreathers, which are closed circuit SCUBA equipment that recycles breathing gas instead of releasing it into the water. It is the "re-breathing" of gas that makes rebreathers ideal for long duration dives, efficient decompression when the gas mix is adjustable, and for the observation of animals in the wild due to the lack of noisy bubbles. These characteristics also make rebreathers ideal for military use, such as when military divers
