Abstract :
Arterial oxyhemoglobin saturation (SpO2) values are currently computed using weighted moving average techniques. Digital signal processing algorithms were explored to identify improved algorithms for SpO2 computation. The fast Fourier transform and discrete cosine transform were identified as potentially superior algorithms. Improvements to the original algorithm using combinations of overlapped processing and averaging techniques were also explored
