..My 2 cents
At around 03:00 on the 24th May, an hour above the balcony I came across 'Chris'. A client with IMG, who was sitting on a ridge. He was covered in wind packed snow ice. I asked him if he was OK.
He replied he couldn't get any oxygen and I realised all his vents on his top out mask were completely frozen up. I snapped off the icicles. and checked the inside of his mask to make sure there was no ice on the inside.
I asked the Sherpa with me - pemba, to check his regulator and at this point we had a disconnect as he wanted to continue climbing and Pemba said that Chris had a sherpa. The problem was I couldn't see any other sherpas, all I could see was a guy sitting down, covered in snow and complaining of no oxygen.
The way that Chris spoke (very slowly)and his apparent apathy, I assumed he was in a slow spiral to serious trouble. I asked for the radio from Pemba and called Adventure consultants and Altitude Junkies. I couldn't remember IMG's or the HRA's frequency. I understandably couldn't get a hold either companies (Mike or Phil) as both groups had summit-ed the day previously and were most likely asleep
Not getting in contact with anyone and Chris still sitting down. I told him that we had to descend. My wife with such a good sherpa, that I didnt really mind leaving them behind. Chris was agreeable to going down and got up and I helped him disconnect his jumar.
As we were starting our descent, Justin from IMG appeared, realizing he was missing one of his group. I told Justin that I thought Chris was hypothermic and needed to descend. Chris was quiet and I assumed acquiesced. I learnt later that Chris did descend with another sherpa. Subsequently talking to Justin, the IMG guide, he said Chris always talked slow and was 'just kinda like that" so perhaps was not as hypothermic as I suspected.
..moving along...by the time I had hit the south summit, I had caught up with my wife. We ascended the Hillary Step together and summit together. By the time, we had got to the Hillary Step, my wife was not 100% completely lucid, having occasional 'panic attacks' and took a big slide off the summit ridge to be saved by the fixed line.
In contrast to my performance past the balcony in aiding and assisting in someone needing rescue, I was in no position whatsoever to aid my wife, apart from utter occasional encouragement. The word I use to describe myself from summit descent basically to halfway down to the balcony is feeble. Basically having the energy to sustain myself down but having nothing in reserve. By the time we were on the ridge between south summit and balcony, we had both improved, to the point we I had some more 'horsepower' over to assist if necessary..but prior to that point, I had absolutely nothing. For a couple of hours, I couldn't help my wife.
We had heaps of oxygen as well, probably between 3-4 l/min above the south summit. (I cant of course verify this.)
Personally, if I got in trouble. I would be devastated if people died trying to save me. I say this with some conviction, as I fell of a abseil line on Ama Dablam and limped back in to Camp 1 as a search team commenced looking for me. I was horrified at the the though of my climbing colleagues putting themselves in danger because of my own stupidity. Of course I wold have been horrified if they had done nothing. As for helping others, I know know that when I can I will help people and it is a reason why I have completed and maintained my WFR.
I also know that at one stage, I was totally unable to help my own wife.
