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 ...
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.
Decompression sickness is caused by inert gas bubble formation in supersaturated tissues, barotraumas of decompression are usually caused by rapid decompression where gas spaces are not able to equalise pressure with the surroundings, and ebullism occurs only in cases of decompression to very low ambient pressures.
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 ...
Divers are exposed to raised partial pressures of oxygen in normal diving activities, where the partial pressure of oxygen in the breathing gas is increased in proportion to the ambient pressure at depth, and by using gas mixtures in which oxygen is substituted for inert gases to reduce decompression obligations, to accelerate decompression, or ...
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.
A USN experiment using symptomatic decompression sickness as the endpoint, compared two models for dive working exposures on air using the same bottom time, water temperature and workload, with the same total decompression time, for two different depth distributions of decompression stops, also on air, and found the shallower stops to carry a ...
