How to Calculate e-Free Water Clearance (eFWC)* 1.Clearance (Cl) of anything (X) = U x*Volume urine/P x 2. Cl (electrolyte, e) = (U Na+ U K) *Volume/P Na Cl (e-free !) = FWC U Na= Urine sodium U K= Urine potassium V = Urine volume = Cl (e) + Cl (e-free !) P Na= Plasma sodium 3. Substitute & rearrange: V = Cl e+ eFWC V = (U Na+ U K)*V/P Na+ FWC ...
