Calcolo del KT/V
• The spKt/V is a dimensionless ratio representing fractional urea clearance. K is the dialyzer blood water urea
• clearance (L per hour), t is dialysis session length (hours, hr), and V is the distribution volume of urea (liters, L).
• K × t = L/hr × hr = L
• V = L
• (K × t/V = L/L = dimensionless ratio
• If we deliver an spKt/V of 1.0, this implies that K × t, or the total volume of blood cleared during the dialysis
• session, is equal to V, the urea distribution volum
