Tool/software:
We use AFE4404 sensors in our smartwatches, and have two questions.
First, Is the algorithm AFE4404 sensors estimating SpO2 based on the paper "Source–Detector Spectral Pairing-Related Inaccuracies in Pulse Oximetry: Evaluation of the Wavelength Shift"? If not so, could you tell me the estimating algorithm?
Second, what precautions should I take to measure SpO2 accurately?
Third, how much measurement time is required to measure SpO2 using AFE4404 sensors?
