Intelligent method and system for monitoring elderly anesthesia target control based on electroencephalogram signals

The invention provides an intelligent method and system for monitoring elderly anesthesia target control based on electroencephalogram signals, and the method comprises the steps: obtaining the injected anesthetic dosage of a target elderly at different target time points, and collecting the electroencephalogram signals of the target elderly at different target time points in real time; determining a consciousness index and an injury index of the target old person under different anesthetic dosages based on the electroencephalogram signal, and determining an initial anesthesia loss perception critical point and a deep and shallow sedation critical point of the target old person based on the consciousness index and the injury index; and determining physiological parameters of the target old person at the critical point, and performing integrated recording on the critical point, the dosage of the anesthetic corresponding to the critical point and the physiological parameters. By determining the consciousness ac
