Climbers on Everest usually acclimate at base camp (~18,000') for five weeks! (Guess they read a lot of books). This increases the red blood cell count (for improved 02 capture ). Besides Oxygen starvation at this altitude, there is the problem of edema (in its many forms) due to low atmospheric pressure. Renal and pulmonary functions can adjust over this period. The problem with rapid decompression at high altitudes ( >25,000' ) is compounded by the effects of gases in tissues and the blood stream coming out of solution rapidly due to the high pressure gradient between the body and the exterior. If the aircraft doesn't descend quickly after sudden decompression, passengers (and crew) may suffer from decompression sickness, stroke, and respiratory failure -- irrespective of supplemental O2.
