A decompression chamber is a sealed environment used to safely manage pressure changes for individuals, particularly divers. It allows for controlled ascent from deep underwater, helping to prevent conditions like decompression sickness, also known as "the bends." Inside the chamber, air pressure can be adjusted to simulate different depths, enabling divers to breathe normally while their bodies adjust. This process helps eliminate excess nitrogen absorbed during deep dives, ensuring a safer return to the surface. Decompression chambers are commonly found in hospitals, research facilities, and diving centers, often operated by trained professionals.
