As the name suggests, a hyperbaric chamber, also known as a Hyperbaric Oxygen Therapy Chamber, is a chamber used for hyperbaric oxygen therapy. In simple terms, this chamber is used to treat patients for lack of oxygen-related issues in the body or for the purpose of rejuvenation by breathing in fresh oxygen. Highly pressurized oxygen is filled in the chamber for the body to breathe in pure oxygen, which is not usually available naturally. The use of hyperbaric chambers is used to treat medical issues like decompression sickness, which is usually an issue caused due to scuba diving; infections within the body because of lack of oxygen in the blood levels; to treat stored bubbles in blood vessels; and other problems which does not require medical supervision.
