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 (DCS), which results from metabolically inert gas dissolved in body tissue under pressure precipitating out of solution and forming bubbles during decompression. It typically afflicts underwater divers on poorly managed ascent from depth or aviators flying in inadequately pressurised aircraft.
Dysbaric osteonecrosis, also known as aseptic bone necrosis, is generally a longer term effect on the bones and joints of divers caused by decompression bubbles and may occur even if no clinical decompression sickness has been diagnosed. [6] [7]
NASA accidentally broadcast a simulation of astronauts being treated for decompression sickness on the International Space Station (ISS) on Wednesday, prompting speculation of an emergency in ...
The principal conditions are decompression illness (which covers decompression sickness and arterial gas embolism), nitrogen narcosis, high pressure nervous syndrome, oxygen toxicity, and pulmonary barotrauma (burst lung). Although some of these may occur in other settings, they are of particular concern during diving activities. [1]
The physiology of decompression is the aspect of physiology which is affected by exposure to large changes in ambient pressure. It involves a complex interaction of gas solubility, partial pressures and concentration gradients, diffusion, bulk transport and bubble mechanics in living tissues. [1]
Starting decompression while bubbles are present appears to be the significant factor in many cases of otherwise unexpected decompression sickness during routine saturation decompression. [ 112 ] Application of a bubble model in 1985 allowed successful modelling of conventional decompressions, altitude decompression, no-stop thresholds, and ...
Engel chooses to sacrifice himself to save Jones, sharing a story of how his selfishness in the past cost a young boy his life. Though Jones develops bleeding from the mouth due to decompression sickness given his fast ascent, he reaches the surface and is rescued by teams from the Marlborough. After learning that Jones has been rescued and ...
