Abstract
It is convenient and useful to be able to obtain the blood concentration from the dialysate concentration alone. We have already reported the usefulness of this concept.
In this paper, the useful formulas were derived by applying the single pool model to SP system (plate type dialyzer and hollowfiber dialyzer) and RSP system (coil dialyzer) with ultrafiltration.
Satisfactory results could be obtained by this method. However, the dialysate concentration was so low that this method led to some errors in clinical therapy. If the accuracy of assay is improved, the results will become more favorable.
The formulas for hemodialysis along this concept were also derived on the basis of 2-pool model, and those for hemofiltration and hemodiafiltration were further derived on the basis of single pool model.
