Paper Abstract

We evaluate the degree of oxygen saturation for several explicit wavelengths in the spectral interval from 650 to 1050 nm (therapeutic window). We analyze the effect of selecting a particular wavelength pair to calculate oxygen saturation considering the known absorption specific coefficients of oxy- and deoxy-hemoglobin. Also, we design a heart simulator to determine the most useful wavelength couple for oxygen saturation for all wavelengths in the therapeutic window. We present a selection map to facilitate wavelength choice. Furthermore, we examine the random noise sensitivity of the trans-illuminated irradiance. This information will be used to determine accurately the illumination sources for NIR spectroscopy and oximetry.
