Abstract
The present disclosure provides systems and methods for calibrating for errors dependent upon spectral characteristics of tissue for a medical device by estimating a spectral characteristic of tissue providing error due to scattering or absorption of emitted light based upon operating the sensor in reflectance mode to generate a first SpOreading and estimating error due to spectral characteristics of skin therefrom, operating the sensor in transmissive mode to generate a second SpO2 reading, and applying a correction to a pulse oximetry transmissive mode measurement to correct for the error dependent upon the estimated spectral characteristic of tissue.
