Thank you for sharing this information, I have been searching for creditable information on Hyperbaric Chambers. I have surviver a Traumatic Brain Injury (TBI) and will continue to research avenues of healing and this is a more natural way than big pharma and is non invasive. I will always be open for others in assisting them in finding their way through the darkness of the current medical care industry that would be more properly titled as "Disease Management" . To all readers may you eat well, may you rest well and chose healthy living over all. Be blessed and breathe!
