The arterial resistivity index (also called as Resistance index, abbreviated as RI), developed by Leandre Pourcelot, is a measure of pulsatile blood flow that reflects the resistance to blood flow caused by microvascular bed distal to the site of measurement. The RI is altered not by vascular resistance alone but by the combination of vascular resistance and vascular compliance. resistive_index.txt Last modified: 2024/06/07 03:00by 127.0.0.1
