Decompression sickness 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 be experienced in other depressurisation events such as emerging from a caisson, flying in an unpressurised aircraft at altitude, and extravehicular activity from spacecraft. DCS and arterial gas embolism are collectively referred to as decompression illness. Since bubbles can form in or migrate to any part of the body, DCS
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,
