Simplified equations for monitoring Kt/V, PCRn, eKt/V, and ePCRn
JT Daugirdas - Advances in renal replacement therapy, 1995 - Elsevier
Although computer solution of the differential equations used in urea kinetic modeling has its
advantages, simplified formulas that are actually approximate algebraic solutions to the
same equations in the clinically useful range are also useful. The Kt/V can be resolved from
the predialysis to postdialysis urea nitrogen ratio (R), the weight loss (UF), session length in
hours (t), and anthropometric or modeled volume (V) using the equation: KtV= In (R-0.008×
t)+(4-3.5× R)× 0.55 UF/V. The equilibrated Kt/V (eKTV) can be estimated from the single …
