Well, to put in my 0.05 cents worth (and someone MUST have said it already) 
the main danger associated with IWR from a medical point of view is the risk 
of O2 induced convulsions.  If you have a protocol which can contain this 
risk then I believe prompt treatment of DCI, even using the "slighly more 
risky" IWR method is preferable to delaying treatment.

Too bad about DAN.  I commend to you the task of keeping data on IWR, 
although I imagine this will be a difficult task.  I suspect you will find 
the percieved risk is much greater than the actual risk, but you won't know 
to you analyse the data.
