RisksBy Mayo Clinic staff
Hyperbaric oxygen therapy is generally a safe procedure, and complications are rare. But, as with any medical procedure, it does carry some risk.
Potential complications include:
- Temporary nearsightedness (myopia) caused by increased blood oxygen levels
- Middle ear and inner ear injuries, including leaking fluid and eardrum rupture, due to increased air pressure
- Organ damage caused by air pressure changes (barotrauma)
- Seizures as a result of too much oxygen (oxygen toxicity) in your central nervous system
