The Empirical Mode Decomposition (EMD) is a

method to decompose non linear, non stationary time series into

a sum of different modes, named Intrinsical Mode Functions

each one having a characteristic frequency. In the present work

we used the EMD to investigate the properties of the recorded

sounds from the Arteriovenous fistula on hemodialysis patients.

Phonoangiographic signals coming from two different vessel

conditions, stenotic and non-stenotic, were analyzed by using

EMD, the mean energy and mean instantaneous frequency per

IMF proved to be good features for classification. Three types

of classification schemes were tested on data from the first IMf

features achieving good results.
