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
CMAS* SCUBA Diver CMAS* SCUBA Diver CMAS * SCUBA Diver, CMAS one-star Scuba diver, or just CMAS * is an entry level diving certification for recreational SCUBA issued by Confédération Mondiale des Activités Subaquatiques (CMAS), enabling divers to undertake accompanied no-decompression dives to a maximum depth of twenty meters. CMAS describes that a One Star Diver shall be deemed "to have sufficient knowledge, skill and experience to procure air, equipment, and other diving services and to plan, conduct, and log open-water dives that do not require mandatory in-water decompression stops, without the supervision of a CMAS Instructor or CMAS Dive Leader, when properly
