Abstract
The aim of this study was to propose an improved method for accurate dialysis dose evaluation and extrapolation by means of Kt/ V from online UV-absorbance measurements for real time and continuous treatment monitoring. The study included a total of 24 treatments from ten uremic patients, seven of whom were male and three females. All patients were on chronic thrice-weekly hemodialysis therapy. The study included both stable and unstable treatments. A known signal processing algorithm, Levenberg-Marquardt, and the newly developed SMART were utilized for the removal of disturbances not relevant for dialysis dose evaluation. Finally, the results were compared with the Kt/ V values based on the blood samples. The new data processing algorithm, SMART, removes disturbances, helps estimate the online Kt/ V with significant precision increase and without any time delay, and more effectively predicts the end Kt/ V for the treatment than the known algorithms.
