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 illness its two components: "Decompression Sickness" and "Arterial Gas Embolism". Many signs and symptoms are common to both maladies, and it may be difficult to diagnose the actual problem. The dive history can be useful to distinguish which is more probable, but it is possible for both components to manifest at the same time following some dive profiles. First aid is common for both DCS and AGE: Treatment for the "Decompression Sickness" and the "Arterial Gas Embolism" components of DCI may differ significantly. Refer to the separate treatments under those articles. Decompression illness Decompression Illness (DCI) describes a range of symptoms
