I was one of the unlucky ones that even had to have ear tubes inserted and still couldn't do the HBO. My ears couldn't hold pressure and you need at least to hold 20 lbs. Mine could do 2 lbs and after the tubes, an instant worse than a migrain headache. They stopped it.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
