A new model of pulse oximetry: Two-dimensional pulsation



Shao Yang, Paul B. Batchelder, Dena M. Raley


We developed a two-dimensional pulsation model of pulse oximetry. Instead of a one-dimensional single layer as in the conventional theory, the arteries pulsate in two dimensions taking into account the effect of probing light that does not pass through the arteries. Computer simulation results based on this model agree well with human test results.
