,

Good point but I think our body labors attempting to get the 40% to 70% we

get from normal oxygen climates and the low 02 levels at on airplanes just

makes our condition worse. This may be why O2 therapy where we're easily

getting 100% 02 is helpful to us. If your theory was valid the 02 therapy

would not be useful. Although we could probably survive (unlike normal

persons) on Everest (if clothed properly), our CFS would probably worsen due

to increased blood alkalinity. Steve B.

That's some funky catch22. We'd survive (a +) but be sick (a -). Thanks

for making clear.

I get very sick in airplanes and at high altitudes, if I am not

breathing supplemental oxygen! I doubt I'd survive very long on Mt.

Everest, no matter how properly I was clothed. ;@)

, Steve et al.,

For what it's worth, here's what I think is going on with the " Mount Everest

phenomenon " in CFIDS: All PWCs operate on glycolysis, even at rest, to a larger

degree than do normal, healthy people. Some PWCs are operating on aerobic

glycolysis at rest, and some are operating on anaerobic glycolysis. The latter

are distinguished by feeling " burning " type pain in their muscles even at rest.

Those operating on aerobic glycolysis use more oxygen than do those on anaerobic

glycolysis, and have a higher basal metabolic rate and more energy. They are

also more vulnerable to the effects of higher altitude. Those operating on

anaerobic glycolysis still need some oxygen to live, but they need less, and the

rate-limiting step in their energy production is not how much oxygen they are

inhaling. Thus, they are not as sensitive to altitude. Unfortunately my files

are in my office, and I'm presently at home, so I can't look up to see whether I

thought you were anaerobic or aerobic, , but I'm guessing that you are

aerobic, based on your experience at higher altitudes. Rich Van K.
