The application of Taguchi methods to parameters optimization for preventing coagulation in artificial kidneys

Abstract

This paper aims to illustrate an application of Taguchi method to identification of the setting optimized for factors affecting coagulation in a hemodialyzer as the benchmark of operations for improved quality and reduced coagulation. In this article, robust parameter designs based on Taguchi methods in association with discussions with the nursing staff apply to the study for investigating the key variables influential to hemodialysis. This paper attempt to improve the quality of hemodialysis by identification of the optimal set of variables and levels involved. The results show that the defect rate dropped from 35 to 8%. Thus, Taguchi methods that did improve the quality of hemodialysis are advised to apply to prevention of clotting during hemodialysis.
