Abstract

A method for estimating evoked potentials (EPs) in a critical care environment where unpredictable transients may occur is presented. Timely detection of these transients may prevent neurological injury. A dynamic Fourier-series model for EPs and an adaptive estimator based on the least mean square and exponentially weighted least squares algorithms were developed. Through computer simulations, it is shown that this technique is effective in removing high electroencephalogram noise and in tracking rapid transients. Cerebral focal ischemia experiments confirmed the effectiveness of this technique. Dispersion of EP spectral power was observed, which suggests the importance of frequency content in diagnosis.
