HBOT chambers/clinics are everywhere. They are often affiliated with Wound Care clinics that serve diabetic clients.

They cost $150 to $200 per session. Usually 40 sessions are needed to start to see a difference.

The primary value to HBOT is in encouraging capillary growth. If there is a lack of capillary blood flow, then HBOT could be helpful. There has not been any evidence yet that shows nerve tissue growth/healing.

The tests on severe TBI patients showed a faster coma recovery and recovery of some motor functions but there was a minimal or a mixed result in the long term.
