First, please understand I do not want to get into an argument here - I truly want to understand why "y'all" think the buddy did the wrong thing.
1. Diver is unconscious underwater . . . Pretty P-poor outlook already.
2. I (assuming the place of the dive buddy) have incurred a [serious?] deco obligation.
3. I know the two divers are already "up".
4. I assume I will execute my part of the CPR taking the victim in.
5. An unconscious diver cannot hold his or her breath. Expanding gas will vent unless the head is locked forward somehow.
So, if I 'escort' this victim to the surface, and decide to take the DCI hit, so then I am possibly paralyzed or in so much pain I am worthless and another victim . . .
How is that the 'right' thing to do? Please help me understand why that would be a better course of action?
I don't think anyone is saying what the buddy did was wrong - but perhaps not what many consider to be the ideal action (if there is such a thing in this type of situation) . If you send someone to the surface and the folks on the boat aren't expecting the victim they might not notice him hit the surface right away, or they might not be able to get to them immediately. Meanwhile the victim is laying face down in the water with or without a reg in and possible drowning. I don't think it is fair yet to say how much deco obligation (if any) was present. From the reports, it sounds like the buddy simply inflated the BC and sent the victim to the surface, even with deco obligations the buddy should have been able to bring them part way up in a controlled manner with a reg held in place (if it was still in the victims mouth).
Getting the victim to the surface quickly is very important but I think what people are saying is that getting them to the surface in an uncontrolled and unexpected manner is not how many of us believe a rescue should be performed.
