| Abstract | ||||
| Monitoring of depth of anaesthesia (DOA) is essential and a challenge to anesthetists because it aims to prevent patients perception of pain, awareness, and recall. However, DOA is very hard to define and not readily measurable. Therefore, a number of monitoring modalities have been considered in an attempt to assess anaesthetic depth and / or the risk of awareness. The mid -latency auditory evoked response (MLAER) has been proposed as the most suitable for monitoring DOA. In this paper, an approach is proposed to enhance the raw auditory evoked response (AER) signal for monitoring the changes in amplitudes and latencies of MLAER waves, which are related to DOA. | ||||
