WebFractional flow reserve (FFR) is a physiological index of the severity of a stenosis in an epicardial coronary artery, based on the pressure differential across the stenosis. Clinicians are increasingly relying on this method because it is independent of baseline flow, relatively simple, and cost effective. The accurate measurement of FFR is predicated on maximal … WebWith a simple manipulation of the void fraction equation for homogeneous flow (eq.

WebFractional flow reserve is defined as the pressure after (distal to) a stenosis relative to the pressure before the stenosis. The result is an absolute number; an FFR of 0.80 means that a given stenosis causes a 20% drop in blood pressure. In other words, FFR expresses the maximal flow down a vessel in the presence of a stenosis compared to the ... Flow Fraction (FF) = dialysate flow rate/blood flow rate (Q d /Q b ). As a result, the lower the Q d is, the lower the FF and the more saturated the dialysate will be. FF prescribed tend to range from 0.2 to 0.5. At a FF of 0.2 for example, dialysate saturations of urea and creatinine are approximately 95% and 90%, respectively.
