One thing I was wondering about that I haven't found much about with various googling around - I get the idea that many climbers use supplemental Oxygen above 8km or so. Are they using Oxygen all the time, even when sleeping, or only when doing strenuous activities? And how long do those bottles last anyways if you're using it all the time? I guess nobody's carrying SCUBA-tank sized tanks around, but will a couple of bottles the size of a 2L bottle last multiple days of continuous use?
- ghaff 9y agoHere's a pretty good summary: http://www.mounteverest.net/expguide/oztech.htm http://www.mounteverest.net/expguide/oztech.htm I don't have personal experience as I've never been that high. They're relatively small tanks (mostly 3 liter) that weigh about 2.5 kg full.
- ufmace 9y agoThanks, that's pretty interesting. Seems they recommend bringing 12 bottles at 2.6kg for about 70 pounds of just oxygen tanks total for the whole climb, and 5 on the actual summit attempt, for ~30 pounds. That's already a lot of weight before you get to all of the clothes, food, water, climbing gear, and other supplies.
- stirlo 9y agoInteresting the OPs article says 5 bottles while the link above says take 12. I guess it depends upon the climber and their fitness.
