<< During a recent Dive Con open water, the subject came up about
whether or not to use 100% oxygen for an injured diver diving on
nitrox.
Any comments?

regardless of whether the diver was breathing 21% or 80% there is still a
nitrogen debt . It is the nitrogen (or helium) that causes the DCI -- if the
diver shows signs and symtoms of decompresison illness the first cause of
action after of course checking for ABC's is to put them on oxygen and
arrange for transport to the nearest hyperbaric facility.
If your fear is that the chamber cant treat someone who has breathed nitrox
-- throw that idea out of your head. It doesnt really make a whole lot of
differecne what they were breathing. This will all be accounted for in the
treatment if one is necessary. Treating a diver who has DCI whether from Air
or Nitrox is of no consequence.
