Abstract:
Three calculation methods to estimation of the total clearance of dialysis patients are evaluated. The basis of calculation are concentration values of urea in blood versus dialysate. The variation coefficient of the measurement errors is 5 percent. The error formation in three estimation formulas is examined. The formula [formula: see text] is most suitable, if as evaluation criteria the variation coefficient of the estimation error are used. The parameters like dialysate flow, blood flow, ultrafiltration rate and dialysate volume are of relative value.
