Question

The equation: Y/1-Y=(pO2/P50)^n

allows the calculation of Y (the fractional saturation of hemoglobin with O₂) given P₅₀ and n.

Let P₅₀ = 26.0 torr, and n = 2.80. Calculate Y in the lungs where pO₂ = 91.0 torr, and Y in the capillaries where pO₂ = 50.0 torr.

Ylungs= ?

Ycapillaries= ?

What is the efficiency of O₂ delivery under these conditions (expressed as Y_lungs - Y_capillaries)?

Efficiency of O₂ delivery =
