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 practice unknown about how inert gases enter and leave the human body. In addition, every individual's body is unique and may absorb and release inert gases at different rates. For this reason, dive tables typically have a degree of safety built into their recommendations. Divers can and do suffer decompression sickness while remaining inside NDLs, though the incidence is very low. Each NDL for a range of depths is printed on dive tables in a grid that can be used to plan dives. There are many different tables available as well as software programs and calculators, which will calculate no decompression
