Decompression illness, or DCI, is a term used to describe illness that results from a reduction in the ambient pressure surrounding a body.
Because of this, evaluation of a diver for possible decompression illness must be made on a case-by-case basis by evaluating the diver's signs and symptoms and not just based on the dive profile.
Decompressionsickness (DCS, also called the bends or caisson disease) is the result of inadequate decompression following exposure to increased pressure.
Decompressionsickness, (DCS), diver's disease, the bends, or caisson disease is the name given to a variety of symptoms suffered by a person exposed to a reduction in the pressure surrounding their body.
Decompressiontables and dive computers have been developed that help the diver choose depth and duration of decompressionstops for a particular dive profile at depth.
Decompression time can be significantly shortened by breathing nitrox (or pure oxygen if in very shallow water), during the decompression phase of the dive.
