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.
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.
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 number of half times chosen to assume full saturation depends on the decompression model, and typically ranges from 4 (93.75%) to 6 (98.44%). [20] [21] Tissue compartment half times used in decompression modelling range from 1 minute to at least 720 minutes. [22]
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 uptake of gas by the tissues is in the dissolved state, and elimination also requires the gas to be dissolved, however a sufficient reduction in ambient pressure may cause bubble formation in the tissues, which can lead to tissue damage and the symptoms known as decompression sickness, and also delays the elimination of the gas.

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 ...
