Tpr hemodynamics
SpletThe Mobil-o-Graph ® is an oscillometric blood pressure measurement validated device able to measure vascular hemodynamics such as central and peripheral blood pressure, augmentation index (AIx), and PWV. 17 Measurements of PWV and AIx are based on the pulsatile pressure changes in the brachial artery.
