Abstract
An automated EP analysis apparatus for monitoring, detecting and identifying changes (adverse or recovering) to a physiological system generating the analyzed EPs, wherein the apparatus is adapted to characterize and classify EPs and create alerts of changes (adverse or recovering) to the physiological systems generating the EPs if the acquired EP waveforms change significantly in latency, amplitude or morphology.
Claims16
An automated evoked potential (EP) analysis apparatus for automatic monitoring, detecting, and identifying of changes (adverse or recovering) to a physiological system generating EP waveforms, wherein the apparatus is adapted to:
- analyze the signal-to-noise ratio of acquired EP waveforms;
- update the baseline using EP waveforms that are analyzed to have an adequate signal-to-noise ratio;
- exclude each EP waveform having an inadequate signal-to-noise ratio;
- track the number of inadequate EP waveforms;
- and
- generate an alert if the number of inadequate EP waveforms exceeds a threshold.
