Two Ohio families have discovered the therapeutic benefits of hyperbaric treatments for their autistic children. Back in 2009, Northeast Ohio coworkers drove down to North Carolina to give their autistic children hyperbaric treatments for autism. During the treatments, cells receive more oxygen than normal and blood vessels and nerves are built.

Treatment facilities are generally associated with hospitals, however there are HBOT chambers that are now available to rent or purchase.
