Yup, that's what I meant.
Here are some stats from Everest taken from my journal:
Basics: normal illnesses: cough, digestive stuff, cuts do not heal, no oxygen to breath - you know: the usual.
Blood and heart rate:
April 19th after 3 nights at base camp 17,600 ft 91 o2, 77 HR
April 27th after 5 nights at Camp 2 21,500 ft 75 o2, 94 HR
May 2 after one night at Camp 2 64 o2, 94 HR
(stays same for five nights) so climbed Lhotse Face with these readings!
May 6th hiked from Camp 2 to Base camp 72 o2, 82 HR
May 8th after one night in Dingboche 13,500 ft 89 o2, 70 HR
I was not very happy with my O2 Sat the last round at Camp 2 and the Lhoste Face but I did OK.
Here are the oxygen levels in air (as compared to at sea level) - continued:
15000 ft - 58%
21500 ft - 45% (camp 2)
23500 ft - 42% (camp 3)
26100 ft - 38% (camp 4)
29035 ft - 33% (summit)
This is without supplemental oxygen. So it shows just how dangerous it is to climb at these higher altitudes without it and my hat's off to those who have and lived.
I would never attempt it for one major reason: the disease I have is vasculitis (imflammation of the blood vessels). Even Dr. Peter Hackett (world's leading high-altitude medical researcher) did not know what was going to happen when I went to altitude.
