ABSTRACT Accurate in vivo measurement of blood oxygen saturation by fiberoptical means is made possible throughout a wide range of hematocrit or total hemo- globin values by using a single R/IR ratio I and calculating the SO2 value therefrom through the use of a second-order polynomial of the form SO2 = Ak2I2 + BkI + C in which A, B and C are hematocrit or total hemoglobin-dependent coefficients which may be contained in a lookup table accessed by a hematocrit or total hemoglobin value selection, and k is a purely multiplicative calibration constant which can be readily determined for any individual fiberoptic system.
