Hypobaric chamber at the Biopol'H, in Catalonia (), used with patients and athletes who need treatment or training with reduced atmospheric pressure. A hypobaric chamber, or altitude chamber, is a chamber used during aerospace or high terrestrial altitude research or training to simulate the effects of high altitude on the human body, especially hypoxia (low oxygen) and hypobaria (low ambient ...
A large range of working pressures are used, depending on the application of the chamber. Hyperbaric oxygen therapy is usually done at pressures not exceeding 18 msw, or an absolute internal pressure of 2.8 bar. Decompression chambers are usually rated for depths similar to the depths that the divers will encounter during planned operations.
deck and saturation decompression chambers [broken anchor], [24] and; hyperbaric treatment chambers. [25] The supply of decompression gases, which may be: carried by the diver, [23] supplied from the surface via the diver's umbilical or bell umbilical, [24] or; supplied in the chamber at the surface.

Hyperbaric medicine includes hyperbaric oxygen treatment, which is the medical use of oxygen at greater than atmospheric pressure to increase the availability of oxygen in the body; [8] and therapeutic recompression, which involves increasing the ambient pressure on a person, usually a diver, to treat decompression sickness or an air embolism by reducing the volume and more rapidly eliminating ...
The hyperbaric atmosphere in the accommodation chambers and the bell are controlled to ensure that the risk of long term adverse effects on the divers is acceptably low. Most saturation diving is done on heliox mixtures, with partial pressure of oxygen in accommodation areas kept around 0.40 to 0.48 bar, which is near the upper limit for long ...
Hypobaric decompression is the reduction in ambient pressure below the normal range of sea level atmospheric pressure. Altitude decompression is hypobaric decompression which is the natural consequence of unprotected elevation to altitude, while other forms of hypobaric decompression are due to intentional or unintentional release of pressurization of a pressure suit or pressurized compartment ...
