An Automatic Peak Detection and Evaluation Program for Somatosensory Evoked Potential (SSEP) Monitoring

  • K. Schwerdtfeger

Summary

An almost fully automatized program for evaluation of somatosensory evoked potentials (SSEP) is described. It is suitable for intraoperative monitoring of SSEP as well as for continuous recording in the intensive care unit. The principles of peak detection, the reliability of peak amplitude and latency measurements, and possibilities to reduce the complex information of evoked potentials to a few parameters are shown. As yet, there has been little clinical experience; however, in practice, a good applicability of the softeware could be shown.
