The "saturation system", "saturation complex" or "saturation spread" typically comprises either an underwater habitat or a surface complex which includesof a living chamber, transfer chamber and submersible decompression chamber, [45] which is commonly referred to in commercial diving and military diving as the diving bell, [46] personnel ...
Diving disorders are medical conditions specifically arising from underwater diving. The signs and symptoms of these may present during a dive, on surfacing, or up to several hours after a dive. The principal conditions are decompression illness (which covers decompression sickness and arterial gas embolism ), nitrogen narcosis , high pressure ...
In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives.
A Saturation system or saturation spread typically comprises at minimum a living chamber, transfer chamber and submersible decompression chamber, which is commonly referred to in commercial diving as the diving bell and in military diving as the personnel transfer capsule, [104] PTC (Personnel Transfer Capsule) or SDC (Submersible Decompression ...
This is most likely in technical divers, saturation divers, and anyone who is treated with hyperbaric oxygen on several occasions. The mortality rate in recreational diving is very low, and the risk of accidental drowning is unlikely to have a significant influence on the average life expectancy of divers.
Chris Lemons spends 28 days living in a pressurized chamber at the bottom of a ship, working on oil fields on the floor of the North Sea.
Normal diving decompression procedures range from continuous ascent for no-stop dives, where the necessary decompression occurs during the ascent, which is kept to a controlled rate for this purpose, [16] through staged decompression in open water or in a bell, [17] [18] or following the decompression ceiling, to decompression from saturation ...
Diving mode where the divers remain pressurised for long enough for the slowest tissues to saturate with the inert components of the breathing gas, usually for periods of several days or weeks, and decompress only at the end of the period. Decompression from saturation is controlled only by the slowest tissue. [75] [76] saturation diving system ...
