Thanks Wopperhead. I noticed that the rescue diver covered the mouth of the distressed diver. It's little bits of info like that that rookies like me may miss and as a result muck things up worse. That should probably be a step in the video. I've crossed over that step in my research and it seems there is some disagreement as to whether it is more important to cover the mouth or to get the diver to the surface quickly. The prevailing opinion, however, seems to be that covering the mouth is the best move.
