On the subject of the chamber, If any of you folks doubt the narcotic properties of O2: I recently had a chance to participate in three chamber rides in Houston, TX. The first time down, somewhere between 40 and 60' on pure O2, I got higher than a kite. Stupid. Made my widest nitrogen induced drool-faced grin look like a mere smirk. I'm talking silly. The attending nurse said she sees it all the time when I asked her about it later. john.r.strohm@BI*.co* wrote: > The guest speaker at the local dive club last night was Dr. Jeff Stone, > director of the hyperbaric chamber at Presbyterian Hospital here in Dallas. > His talk was about wound treatment using adjunct hyperbaric oxygen > therapy. > > One of his slides showed their standard treatment profile.
