Hyperbaric chamber: a pressurized chamber used to deliver high-pressure oxygen therapy. Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a closed environment in which the air pressure is 1.5 to 3 times greater than normal air pressure. The entire body is placed inside a hyperbaric chamber for HBOT.
Hyperbaric oxygen therapy is the accepted treatment for decompression sickness that can occur following scuba diving. Other conditions that are treated with hyperbaric oxygen therapy include certain infections, poorly healing wounds, carbon monoxide poisoning, and air emboli (bubbles of air) in the blood vessels.
A hyperbaric chamber is a medical device that has been cleared by the US FDA.
