SYSTEM FOR INDEX CALCULATION OF ANESTHESIA DEPTH USING EEG SIGNAL AND RESOPNSE CHARACTERISTIC OF NEUROMUSCULAR

摘要

PURPOSE: An anesthesia depth determining system using the response characteristics of an EGG signal and a nerve root stimulus improves the accuracy of determination by using a standard parameter. CONSTITUTION: An anesthesia depth determining unit (50) determines anesthesia depth 1 based on a standard parameter. An EGG signal analyzing unit analyzes a measured EGG signal. A nerve root stimulus generating unit (100) generates multiple nerve root stimulus patterns. The nerve root stimulus generating unit transmits the nerve root stimulus pattern to a predetermined position of a patient. A response characteristic transmitting unit (300) transmits a response signal of the patient for each nerve root stimulus pattern.
