How does a decompression chamber work?

A decompression chamber, also known as a hyperbaric chamber, is used to treat conditions related to pressure changes, such as decompression sickness in divers. It works by allowing patients to breathe pure oxygen at higher-than-normal atmospheric pressures, which helps dissolve nitrogen bubbles in the blood and tissues. The chamber gradually reduces pressure after treatment, allowing the body to safely eliminate excess nitrogen. This controlled environment promotes healing and reduces the risk of complications associated with rapid decompression.
