One of our instructors insists that trainees should be taught to bring up a victim at the standard BSAC ascent rate of 1 minute for the last 6m. He makes them take 30 seconds to bring the victim up from the bottom of the 3m deep pool that we use. In a real life situation, I would have thought it more sensible to use a faster ascent rate to get a non-responsive diver to the surface as soon as practical subject to not causing a massive risk of DCS. If a diver becomes unresponsive shortly after beginning a dive to 10m, there is very little risk in a fairly fast ascent but obviously if the diver is well into deco, the risk is rather different.
BSAC instructor info is not very clear about this subject, at least not that I can find and I would be pleased if anyone can point me to the appropriate instructions.
What does TDF think should be taught?
