This is what I am wondering. Everybody is on their high horse assuming people making an out of control ascent is holding their breath. In all likelyhood I doubt most of them do because it's just not a natural reaction to hold air in as you rise. Everybody is trying to stop AGE because of a breath holding incident when people may be darting to the surface becuase they have a mouth full of water. Regardless of why somebody is bolting to the surface, if you don't know why, you should at least try to figure out if they are breathing/don't have a mouth full of water before you stop them. AGE from a breath holding incident is a theory that may or may not happen to that particular person as you have no idea if they are holding their breath -- you are just making a wild guess. Holding somebody down in the water without knowing their breathing state is basically drowning them. AGE seems to be pretty uncommon from the stats and there are plenty of out of control ascents. I lost a flipper at 140ft. Tried to fin up but couldn't get much further than 130ft without A LOT of trouble. Put a little too much air in the BCD to compensate, my dump valves didn't seem to work, and I took a ride to the surface. Classic case for DCS but no problem -- I was letting my air out of my lungs. Had I had a mouthful of water and somebody stopped my ride, I would have drowned. Don't just hold people underwater unless you have a guess why they are bolting.Do you really mean people holding their breath or people who are ascending without a regulator in their mouth?
