Renal Blood Flow [RPF1]

$RBF = [( U_"PAH" * V_U ) / P_"PAH" ] / (1 - "HCT" )$

$"Hematocrit"$

$"Concentration of PAH in Plasma"$

$"Concentration of PAH in Urine"$

$"Volumetric Flow Rate of Urine"$

This equation computes the renal blood flow, RBF, from the renal plasma flow (as computed via the equation-in-equation for RPF1) and the volume percentage or red blood cells (the hematocrit).

Inputs to this equation are:

U_"PAH" - the urine concentration of para-aminohuippurate in the urine sample
P_"PAH" - the plasma concentration of para-aminohuippurate in the blood samplesample
P_"PAH" - the plasma concentration of para-aminohuippurate in the blood samplesample
HCT - the hematrocrit, also known as the packed cell volume (PCV) and the erythrocyte volume fraction (EVF)
