Decompression sickness (DCS; 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 decompression.
Decompression sickness is usually avoidable by following the requirements of decompression tables or algorithms regarding ascent rates and stop times for the specific dive profile, but these do not guarantee safety, and in some cases, unpredictably, there will be decompression sickness.
Inner ear decompression sickness, (IEDCS) or audiovestibular decompression sickness is a medical condition of the inner ear caused by the formation of gas bubbles in the tissues or blood vessels of the inner ear. Generally referred to as a form of decompression sickness, it can also occur at constant pressure due to inert gas counterdiffusion ...
Altitude decompression may occur as a decompression from saturation at a lower altitude, or as decompression from an excursion to a lower altitude, in the case of people living at high altitude, making a short duration trip to low altitude, and returning, or a person decompressing from a dive at altitude, which is a special case of diving ...
1868 – Alfred Le Roy de Méricourt described decompression sickness as an occupational illness of sponge divers. [3] 1873 – Dr. Andrew Smith first used the terms "caisson disease" and "compressed air illness", describing 110 cases of decompression sickness as the physician in charge during construction of the Brooklyn Bridge.
Risk management for decompression sickness involves following decompression schedules of known and acceptable risk, providing mitigation in the event of a hit (diving term indicating symptomatic decompression sickness), and reducing risk to an acceptable level by following recommended practice and avoiding deprecated practice to the extent ...
Andreas Grassl (born 25 October 1984) is a German man found in England in April 2005, who remained unidentified for a long time due to his refusal to speak, communicating instead through drawing and playing the piano.
The risk of decompression sickness after diving can be managed through effective decompression procedures and contracting it is now uncommon, though it remains to some degree unpredictable. Its potential severity has driven much research to prevent it and divers almost universally use decompression tables or dive computers to limit or monitor ...
