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
Decompression equipment decompression stop. Shot line configurations: A Jonline is a short line used by scuba divers to fasten themselves to something. The original purpose was to fasten a diver to a shot line during decompression stops in current. The line is typically around 1 m (3 feet) long and equipped with a clip at each end. One clip is fastened to the diver's harness, and the other is used to fasten the line to the anchor line. In current this relieves the diver from holding on to the anchor line during the decompression stop. The jonline is named after Jon Hulbert,
