Abstract

In this paper a method for identifying and classifying hemodialysis patients based on the relative blood volume (RBV) is presented. A group of 42 hemodialysis patients were treated with a special ultrafiltration pattern. The response in RBV to this pattern was recorded and analysed. Using the steady state and time constant of a fitted and estimated function, the patients can clearly be separated into 4 different groups. The analysed parameters give information about the fluid-status, the hemodynamic stability and the physiologic and pathologic patient conditions
