ABSTRACT The depth of anesthesia is generally considered adequate if the patient neither moves in response to surgical stimulus nor shows any signs of autonomic reflexes. So the measuring of depth of anesthesia is very important because it helps the anesthetist to monitor the anesthetic state of the patient from the start of giving the anesthetic drugs up to the patient awareness and helps him to control the required amounts of the anesthetic drugs during the surgery. The middle latency auditory evoked response (MLAER) was seemed to be the most promising measure of DOA, which is independent of the agent being used; the monitoring of DOA is complex and dependent on many factors, which vary between patients and operating procedures. Fuzzy set theory can be adapted for handling complex and inexact knowledge (DOA). This paradigm seems to be suitable for medical process, since it depends upon expert experiences which are not precisely quantifiable such as patients' subjective sensations, interpretation of clinical signs and effects of instrumental accuracy. The aim of this paper is to extract significant features from the processed auditory evoked response (AER) signal using ARX model which, describing the changes in amplitudes and latencies of MLAER waves and merging together using fuzzy logic to create a reliable index for DOA every 30 sec.
