Abstract
Today there are some kinds of diagnostic methods to measure the degree of health under hemodialysis for patients in chronic renal failure, but on the other hand they have a many of indefinite symptoms in this treatment indeed. We hope to get a new index to catch timely their physical conditions at ease. As a clue we notice the pulse wave-responses based on circulatory kinetics in hemodialysis patients and investigate Fuzzy features of their test data.
