WebEjection fraction refers to how well your heart pumps blood. It is the amount of blood pumped out of your heart’s lower chambers (ventricles) each time it contracts. To … WebSep 7, 2010 · Void fraction is related to Slip Ratio S by the equations: (1) where U G and U L are the superficial velocities of the gas and liquid phases, p L and p G the liquid and gas densities and x the flow quality (see article on Multiphase Flow for definitions). For a homogeneous flow, S = 1 and: (2) where β is the volume flow fraction of the gas phase.

WebThe ejection fraction (EF) formula equals the amount of blood pumped out of the ventricle with each contraction (stroke volume or SV) divided by the end-diastolic volume (EDV), the total amount of blood in the ventricle. To express as a percentage, you would multiply by 100. So, EF = (SV/EDV) x 100. In other words, the ejection fraction is 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. WebThe filtration fraction (FF) is the ratio between the glomerular filtration rate (GFR) and renal plasma flow (RPF). A healthy individual has a GFR of around 120 ml/min (milliliters per …
