title: Prediction of PO2 from SO2 using the standard oxygen hemoglobin equilibrium curve.
abstract: We have fitted polynomial equations to three major segments of the standard oxygen hemoglobin equilibrium curve (OHEC) using oxygen saturation (SO2) rather than oxygen tension (PO2) as the independent variable. Hill's transformation contributes substantially to the very small residual errors of PO2, less than 0.21 Torr for all points. This characterization of the OHEC is more precise, and for certain applications more conveniently used than other available equations.
