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

phathophysiology Paul Wheat (PW) is a 23 y/o male who suffered a hit-and-run auto-pedestrian accident and sustained multiple abrasions, a concussion, and a deep laceration of his left thigh. He was discovered approximately 2 hours after the incident and is now in the emergency room [ER]. Paul’s initial diagnostic workup, vital signs and lab work reveal a 2500 mL blood loss. A urinary catheter is inserted to monitor urine output. Currently, Paul’s urine output is 15 mL/hr and is clear but dark amber in color. What type of renal failure is PW likely developing? What is the underlying cause?
