Based on the data, answer the following questions
a). Estimate the fractional saturation of whole blood and stripped hemoglobin at the pO
2
found in the lungs (100 mm Hg) and in the tissues (30 mm Hg).
pO2
whole blood
stripped
hemoglobin
100 mM Hg
30 mm Hg
b). Under these conditions, what percentage of the oxygen bound in the lungs is delivered
to the tissues?
percentage delivered
whole blood
stripped hemoglobin
c). Based on the above answers, what would happen to the recipient if we were to use
stripped hemoglobin in a blood transfusion?
