Self-calibrated pulse oximetry algorithm based on photon pathlength change and the application in human freedivers

Pulse oximetry estimates the arterial oxygen saturation of hemoglobin ( ) based on relative changes in light intensity at the cardiac frequency. Commercial pulse oximeters require empirical calibration on healthy volunteers, resulting in limited accuracy at low oxygen levels. An accurate, self-calib...
