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
SS Edmund Fitzgerald can in "Edmund Fitzgerald"s pilothouse. That same year, Terrence Tysall and Mike Zee set multiple records when they used trimix gas to scuba dive to "Edmund Fitzgerald". The pair are the only people known to have touched the "Edmund Fitzgerald" wreck. They also set records for the deepest scuba dive on the Great Lakes and the deepest shipwreck dive, and were the first divers to reach "Edmund Fitzgerald" without the aid of a submersible. It took six minutes to reach the wreck, six minutes to survey it, and three hours to resurface to avoid decompression sickness, also known as "the
