Please,
I am searching for an algorithm to calculate SpO2 using a AFE4400.
I saw this formula on a forum but i did not understood what ACrms mean..
R = (ACrms of Red / DC of Red) / (ACrms of IR / DC of IR)
Where "DC of Red" and "DC of IR" mean: "Average value over time". And "ACrms" means: alternating amount within the signal values over time
% SpO2 = 110 - 25 × R
Please could somebody help me.
