2. Before leaving for Mount Everest base camp, a climber's hematocrit is measured at 40%, PAO2 =100 mm Hg and hemoglobin content and saturation is normal. Following 2 weeks at base camp her hematocrit is measured at 60% and PAO2 = 40 mm Hg and O2-Hemoglobin Saturation is 60%. a. What causes this increase in hematocrit? b. How does the O2 concentration in the blood following 2 weeks of acclimatization compare to the O2 concentration in the blood at sea level? Show your work. C. What effects on blood flow will occur at altitude due to changes in hematocrit? Use the diagram provided as reference. Show quantitative evidence for your answer. Relative Viscosity 8 0 AK 20 Blood Viscosity Measured in a Viscometer 20 40 Hematocrit (%) d. How may you modify blood vessel radius to normalize blood flow under these conditions? Provide a quantitative answer. 60
