Abstract
Previously, we analyzed the classical theory for oxygen saturation in blood. We proposed a novel model to reduce noise effects, and a methodology based on standard deviation oxygen saturation maps to select the optimal wavelength zones to improve oximetry measurements. We evaluate the oxygen saturation measurement for different wavelength pairs in the spectral range from 650 to 1050 nm looking for accurate saturation values. We perform a cross-talk analysis in hemoglobin absorbance spectra in order to find out the optimum center wavelength for light sources of extended spectrum like a led. We compare the oxygen saturation results obtained with different peak wavelengths considering the cross-talk effect between oxy- and deoxy-hemoglobin signals.
