The following data describe the binding of oxygen to human myoglobin at 37oC.

P02 (mm Hg) = 0.5 1 2 3 4
Theta = .161 .277 .434 .535 .605

P02 (mm Hg) = 6 8 12 20
Theta = .697 .754 .821 .885

From these data, estimate:

a). P50
b) the fraction saturation of myoglobin at 30 mm, the partial pressure of O2 in venous blood.

I donâ€™t know how to start and go about solving this problem.

Should I use this formula to calculate P50? Y=[S]^n / [S]^n + [S50]^n
