What does the term "hyperbaric chamber" refer to?

The term "hyperbaric chamber" specifically refers to a pressurized environment designed for the treatment of decompression sickness, which, commonly known as "the bends," can occur when divers ascend too quickly after being underwater. In a hyperbaric chamber, pressure is increased above normal atmospheric pressure, allowing for greater absorption of oxygen by the body and facilitating the removal of nitrogen that has accumulated during the dive. This treatment is crucial for reducing symptoms of decompression sickness and accelerating recovery.

This understanding highlights the unique role of hyperbaric chambers in medical treatments related to diving, distinguishing them from other options like storage facilities for diving gear, training environments, or protective suits.
