No, Harvey. That wasn’t the point I was discussing at all. I made a statement about acclimatization. You apparently didn’t understand my point, “extrapolated” what I said, and “clarified” by basically saying that I was wrong. My second post explains my thinking in more detail. Your second post adds more information, but doesn’t really refute anything I have said. I stand by everything I have said here.

Yes. I had Cheyne Stokes breathing at 14,700’ on Denali. I woke up several times gasping for breath. Half of a 250mg tablet (and a quarter of a tablet every 12 hours after that) eliminated my symptoms for the rest of the trip. Most of the others had a similar experience at 12,800’.
