An Index of Depth of Anaesthesia Based on Wavelet Analysis of Middle Latency Auditory Evoked Potentials

This paper presents a new method to monitor the depth of anaesthesia using wavelet analysis of middle latency auditory evoked potential (AEP). This method uses much less sweeps comparing to existing methods and make the fast extraction of AEP signal possible. Moreover, the result shows a better relativity with the depth of anaesthesia.
