WebCPO was calculated as (mean arterial pressure×cardiac output)/451, and aortic pulsatility index (API), a novel hemodynamic metric of cardiac function, was calculated as (systolic–diastolic blood pressure)/pulmonary capillary wedge pressure (PCWP). 8 Both were then correlated with preload (end-diastolic pressure), afterload (Ea), Ees, and cardiac … WebJun 25, 2024 · defining the pulsatility index. Pulsatility Index (PI) = (Peak systolic velocity – end diastolic velocity)/(mean velocity) A normal pulsatility index is roughly 0.5 – 1.2 (Nelson, 2024); One advantage of the pulsatility index is that it is robust to alterations in the angle of insonation of the vessel (since off-angle measurement will affect all velocities equally).
