ADAPTIVE CALIBRATION PULSED OXIMETRY METHOD AND DEVICE

摘要

A method for determining an arterial blood oxygen saturation level according to this invention includes measuring the light transmittance through tissue of light of a first wavelength, and a second wavelength (20). A steady-state component of the measured light transmission is used to select an appropriate calibration curve (30). A pulsatile component of the measured light transmission is used to determine the arterial blood oxygen saturation level using the selected calibration curve (40). An oximetry system is also provided.
