This is the typical non-diver-ophthalmologist party line. Anyone with even a high-school physics education would know that while diving, the PO2 is *higher* than normal so arguments about insufficient O2 on the eyes are baseless. I'm always amazed at how little MDs actually know outside the procedures they've memorized. A friend of mine *thought* he had an elbow pain after dive a few months ago. DAN told him he had to go for a chamber ride. He didn't want to because he thought it was more likely just soreness (and it was 2am), but he went anyway. He was made to sit in the ER for hours because the physician trained in hyperbarics was not available. When he asked for O2, the universally accepted standard treatment, he was denied it because the attending wasn't sure if it was a good idea. She had her nose buried in a book trying to figure out what to do. The slightest education in physics would have told her what to do. Anyway, my point is that you shouldn't believe everything your doctor tells you. Most of the time, they're going to quote you some standard hyper-conservative line that will keep you safe, but may not be realistic. -Mike Rodriguez <mikey@ma*.co*> -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
