| abstract |
The present invention provides an apparatus for monitoring the depth of a true anesthetic state of an object. The apparatus includes a memory for storing a program for estimating an anesthetic depth and a processor for executing the program, , Obtains the electroencephalogram data and electrocardiogram data of the object before and after the anesthetic agent is actually input, extracts the causal model by modeling the causal relationship between the electroencephalogram data and the electrocardiographic data, and calculates the true anesthetic depth of the object based on the causal relationship model . |
