Hyperbaric oxygen therapy is also called hyperbaric medicine. It is the usage of oxygen at a higher level compared to the normal atmospheric pressure.
Hyperbaric oxygen treatment is approved to treat diseases such as gas embolism or air, carbon monoxide poisoning, wound problems, crush injuries, outstanding blood loss, skin grafts, burns, and autism, compartment syndromes, inflammatory bowel disease, hearing loss, decompression sickness, and many others.

The therapy treats decompression sickness and gas embolism by increasing pressure. The high concentration of oxygen keeps the oxygen-starved tissues living and eliminates nitrogen in the bubble which makes it smaller until it only consists of oxygen, which can be reabsorbed then by the body.
After eliminating the bubbles, then the strain is slowly reduced back to atmospheric levels. Patients have been treated usually in hospital clinics. An hour of HBOT session could cost between $108 and 250$ privately clinics and more than $1,000 in hospitals.
The type of hyperbaric chamber used for HBOT was a hard-shelled pressure vessel. It can be a semi-portable, one-patient unit to multi-patient units that can handle eight or more patients.
With the latest advances, portable soft chambers were manufactured. Hard and soft chambers differ in their attributes, efficacy, and safety.
At present, the chambers could accommodate both individual and medical staff within the room. The patient breathes from oxygen helmets which is a soft plastic helmet with a seal around the neck or from oxygen masks.
Patients breathe 100 percent of oxygen through treatments and most of the time with regular air breaks to minimize the risk of oxygen toxicity.
