MEDICAL SYSTEMS AND METHODS FOR DETECTING CHANGES IN ELECTROPHYSIOLOGICAL EVOKED POTENTIALS

An automated evoked potential analysis apparatus for improved monitoring, detecting and identifying changes to a patient's physiological system, wherein the apparatus includes an input device for obtaining electrical potential data from the patient's physiological system after application of stimulation to a patient's nerve and a computing system for receiving and analyzing the electrical potential data. The computing system includes a processing circuit configured to: generate a plurality of evoked potential waveforms (EPs) based on the electrical potential data and calculate an ensemble average waveform (EA) of a subset of the plurality of EPs. The computing system is further configured to apply a mathematical wavelet transform to the resultant EA, attenuate noise components from the transformed EA, and apply an inverse transform to the transformed EA to generate a denoised EA.
