<unk>  (abbreviated<unk> ; also called divers' disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during<unk> .<unk>  most commonly occurs during or soon after a<unk>  ascent from underwater diving, but can also result from other causes of depressurisation, such as emerging from a caisson,<unk>  from saturation, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft.<unk>  and arterial gas embolism are collectively referred to as<unk>  illness. Since bubbles can form in or migrate to any part of the body,<unk>  can produce many symptoms, and its effects may vary from joint pain and rashes to paralysis and death. Individual susceptibility can vary from day to day, and different individuals under the same conditions may be affected differently or not at all. The classification of types of<unk>  by its symptoms has evolved since its original description in the 19th century. The severity of symptoms varies from barely noticeable to rapidly fatal. Risk of<unk>  caused by diving can be managed through proper<unk>  procedures and contracting it is now uncommon. Its potential severity has driven much research to prevent it and divers almost universally use dive tables or dive computers to limit their exposure and to monitor their ascent speed. If<unk>  is suspected, it is treated by hyperbaric oxygen therapy in a<unk>  chamber. Diagnosis is confirmed by a positive response to the treatment. If treated early, there is a significantly higher chance of successful recovery.
