I'm guessing the only thing that would have saved him would be to get him off the mountain.. and fast. Hypothermia + O2 deprivation, no way they were going to revive him up there. :(
If they had tried and got themselves killed (most likely outcome) we could at least say they died heros and the Mt would have racked up a couple more kills.
The fact that there were 40 people up there, and they all knew there was nothing they could do. It food for thought alright.
It's just not a sane place to be
