The following is a list of applications of Hyperbaric Oxygen Therapy (HBOT) being used worldwide. Most are considered experimental and controversial by the mainstream medical community, with only testimonials and anecdotal evidence for benefit. Medical insurance in the United States and elsewhere will often refuse payment.

Conditions marked with an asterisk (*) below might be covered by Medicare and other medical insurance in the U.S. For a list of conditions, click here.
