Abstract

A method and system for measuring a physiological parameter, comprising collecting a first absorbance at a first wavelength, chosen to be primarily absorbed by water; collecting a second absorbance at a second wavelength, chosen to be primarily absorbed by hemoglobin; and combining the first signal and the second signal to generate a combined plethysmograph signal which is proportionate lower in noise caused by motion-related interference.
