Most airline flights have a cabin altitude of 8,000 feet. At this altitude, the oxygen has a challenge to cross cellular membranes. For those with a brain injury, this challenge is more pronounced. Studies have show a cognitive performance difference between those with and without a head injury history when at 8,000 feet.

It would be interesting to see if a session in an HBOT chamber reduces the struggles after a long flight by helping to push oxygen across the cellular membranes.

It would follow that extended periods of poor oxygen would alter blood chemistry in a variety of ways. O2 levels effect pH levels and other issues.

Bachisimo, if you have access to an HBOT clinic, it would be worth trying a session the next time you take a long flight.
