Diving chambers provide a controlled environment for divers during decompression after deep-sea dives. They're used to gradually reduce the pressure on divers, preventing the bends or other injuries. Synonyms for diving chambers include hyperbaric chambers, pressure chambers, treatment chambers, and recompression chambers. These terms describe the function of the chamber and emphasize the importance of controlling the pressure. Other related terms include saturation chambers, which allow divers to stay at depth for extended periods, and bell chambers, which are used to transport divers to and from a dive site. No matter the term used, diving chambers are an essential and lifeline safety device for divers operating in deep waters.
