NIH grant awarded to develop a novel pulse-oximetry method to reduce bias in arterial oxygen saturation measurement, improving accuracy for diverse skin tones.
Description
This research project aims to pioneer a noninvasive and auto-calibrated pulse-oximetry method that more accurately and unbiasedly determines a person's arterial oxygen saturation than conventional pulse-oximetry. The project will develop an inverse model to recover person-specific finger optical properties, spatial mapping of pulsatile hemodynamics, and a custom wearable device for clinical testing.
