Decompression sickness DCS, and there is some evidence that marine mammals such as cetaceans and seals may also be affected. AW Carlsen has suggested that the presence of a right-left shunt in the reptilian heart may account for the predisposition in the same way as a patent foramen ovale does in humans. Decompression sickness Decompression sickness (DCS; also known as divers' disease, the bends, aerobullosis, or caisson disease) describes a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation. DCS most commonly refers to problems arising from underwater diving decompression (i.e., during ascent), but may
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
