Hi Folks
	After following this thread for a while I have a question. If you are
correctly(sic) set up for OWR with a FFM etc and you are down as a tender. If
the diver under treatment does go into convulsions due to O2 tox what is the
correct procedure? Someone mentioned that you should never bring a convulsing
diver to the surface due to the risk of embolism, if you do not have the
ability to switch the gas that the diver is breathing, will the convulsions
continue while the diver is under pressure and breathing O2? Does this mean
that you must have the ability to switch gasses before considering IWR.

					Thanks
						Terry

P.S. has someone done the calculations for the AusIWR table for the aprox
number of cu ft of O2 that would be required to complete the treatment.(I
know I am being lazy but my brain has shut down for the holidays). If you
were to consider the use of an O2 rebreather for the treatment, how often
would you have to flush the loop?
