Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 80 mm Hg. Assume hemoglobin is 50% saturated with oxygen at a partial pressure of 24 mm Hg and that the Hill coefficient is 3.
Use the Hill Equation to determine the fractional saturation of hemoglobin in equilibrium with blood that has a partial pressure of 1.9 mmHg.
Make a list of the different physiological equations:
Equation to calculate CaO2 (content of oxygen in arterial blood) and assume 100% saturation and no oxygen diffused in solution; all is carried by hemoglobin (what is the hemoglobin binding constant?) =
