Oxygen Transport on Mount Everest: The Effects of Increased Hematocrit on Maximal O2 Transport
the decreased arterial O2 pressure (PaO2) and blood O2 percent saturation (O2aHb%) of which, however, the latter may be more than compensated for in the acclimated, by the increased RBC and blood hemoglobin (Hb) concentration;
hypoxia of the myocardium, that may reduce maximal cardiac output (Q̇max) both in acute and chronic hypoxia;
limited to the acclimated, the effects on Q̇max of the increased blood relative viscosity (frem 5 to 11, according to personal measurements by the Ostwald viscometer) brought about by the high increase in the hematocrit (Hot).
