In this paper the phenomena in tissue optics that influence reflectance pulse oximetry are described systematically for the purpose of making the subject accessable to those who are involved in pulse oximetry but less familiar with tissue optics. The results of Monte Carlo simulations have been used to show that reflectance pulse oximetry does not only depend on the differences in absorption coefficient caused by the blood volume changes, but also by changes in the reduced scattering coefficient, and by the pulse-independent parts of the absorption and reduced scattering coefficients.
