Effect of postural changes on lower limb blood volume, detected with non-invasive photoplethysmography
This paper describes the effect of passive leg raising on blood volume change in the lower limb, using a dual probe photoplethysmography (PPG) system employing a tissue optics model. The normalized AC/DC ratio and DC value are introduced from the model to evaluate the dynamic pulsation and total blo...
