<p>A method for monitoring the depth of anesthesia experienced by a patient includes identifying a change in one or more evoked bio-potentials (100) using a wavelet transform, and calculating at least one index (108) indicative of the depth of anesthesia experienced by the patient based on the changes in the evoked bio-potentials (100) over a period of time during which anesthesia is administered to the patient. Optionally, changes in random electroencephalogram activity, pulse oximetry measurements, and blood gas measurements are combined with the changes in the evoked bio-potentials (100) in calculations of the index. The resulting indices are optionally displayed in a graphical representation (110) of the level of anesthesia experienced by the patient.</p> |
