Abstract
In one embodiment, a method for creating a blood oxygen saturation (SpO) value, the method comprises receiving one or more photoplethysmography (PPG) signals for SpOdetection from one or more PPG sensors; receiving one or more PPG signals for characterizing a heart rate from the one or more PPG sensors; using the one or more PPG signals for SpOdetection, forming one or more SpOdatasets wherein the SpOdatasets respectively comprise one or more noise components; removing the one or more noise components from the one or more SpOdatasets that are inconsistent with a feature of the one or more PPG signals characterizing the heart rate to produce one or more filtered SpOdatasets; and using the one or more filtered SpOdatasets, creating and storing the SpO.
