4. Conclusions
We describe a four wavelength continuous wave near-infrared algorithm for estimating hemoglobin oxygen saturation in tissue using single depth attenuation measurements. The 40 nm gap second derivative algorithm and in vitro calibration method provided StO2 measurements of reasonable accuracy that were applied across a variety of tissues and probe spacings with no measured or assumed values for optical pathlength or optical scattering.
