	What stats exist on the difference between Normo and Hyperbaric
oxygen for DCI treatment? 100% O2 on the surface is easy to apply and
common (even amongst us not-so-technical divers); everyone recognises
that the risks of having a pure O2 kit around, and misapplying it are
minimal compared to the benefits (Ok, BSAC require a medical which would
pass you for pure O2 use anyway - I don't know if anyone else requires
that).

	Do we get 50% greater success rates for IWR? 20%? 200%? Any
comments on lab/field studies or even in vitro/ex vivo work would be of
interest. 

	Jason. No clan at all, they were a victorian invention.

	PS *any* database for IWR would be useful. Given that most IWR
users appear to be techies, would it be worth approaching IANTD/ANDI/joe
blows happy helium house to disseminate information - either to recieve
replies themselves or to forward to another party?
