Abstract :
The latency and amplitude of the midlatency auditive evoked potential´s (AEP) Nb-trough has been found to indicate the depth of anaesthesis. The aim of this paper is to present a system that reliably estimates these parameters without a long time delay. The result shows that it is possible to estimate and track changes in latency and amplitude of the Nb-trough with a delay below 1 minute at a stimulus rate of 8.4 Hz
