Oxygenation at high pressure (OHP) has been used to treat a range of conditions, including decompression sickness, peripheral obstructive disease, anaerobic infection, and sudden deafness. Recently the effect of OHP on spinal lesions was reported.
We used OHP to treat seven patients with spinal disorders. In the OHP chamber, we gradually increased the atmosphere up to 2.5 atmospheres absolute (ATA) over fifteen minutes and kept it at this level for 60 minutes.
We then reduced the atmosphere to 1.0 ATA. This treatment was given once a day. However improvement in symptoms was observed in only one case, and we concluded that this therapy was not effective for treatment of spinal lesions.
