from my experience in assisting an unconscious non-breathing rebreather diver to the surface, all this talk of diagnosis underwater is a waste of time! I got to see from 6 inches away a diver convulse, recover try to bail out to OC reg, convulse again without reg in mouth, stop breathing, turn blue rapidly at 42m. Me and his buddy took him to the surface as fast as we could (to our own personal detriment). the diver was revived on the boat, choppered out (revived again) and taken to hospital.
Here you have a circumstance warranting immediate surfacing... convulsing with loss of airway. This is appropriate for that particular circumstance.
Peculiar about Rebreather's is there are scenarios where an unconcious buddy, but breathing (thanks to either a FFM or good neckstrap) should undergo an alternative rescue procedure in order to avoid further unnecessary injury.
This is particularly important for me as I apply the advice from this forum in advising my skilled OC buddies on how to rescue me. I have a BOV, and a good neckstrap that firmly holds my mouthpeice in. If I'm found convulsing, or unconcious, with a deco obligation, why should OC rescue techniques apply?
