There has not been a simple parameter by which hemodialysis treatment can be measured. Dialysis hours on the machine per treatment or per week is usually difined, but this method is thought to be unsatisfactory. Because important factors are not taken into account if dialysis is expressed in terms of time alone. Hemodialyses of equal length are not necessarily equally effective, since the rates of blood flow, which significantly affects the efficiency of dialysis, are often changed during a treatment and from one treatment to another.
We use the total dialyzed blood volume in liters as a quantitative parameter for the evaluation and prescription of dialysis. The total dialyzed blood volume can be easily measured by counting the revolution of the blood pump which was equipped by a digital revolution counter. Total dialyzed blood volume in liter is correlated with the body weight of the patient in kilogram. We chose a total dialyzed blood volume in liter, which is 117% of body weight in kilogram. The corresponding number of revolutions can be easily determined with relation to either liters of total dialyzed blood volume or kilograms of body weight. The therapeutic effect of dialysis can be maintained on an optimal and even level in 17 chronic hemodialysis patients.
