Abstract
To assess the sedation level of patients undergoing general anesthesia, many sedation indices based on the electroencephalogram (EEG) have been proposed. In this paper, we calculate basic elements for determining sedation indices using wavelet transform, and compare the results with those using short-term Fourier transform. Also, we propose novel basic elements using wavelet transform and study their availability for the sedation index.
