Changes in EEG frequency characteristics during sevoflurane general anesthesia: feature extraction by variational mode decomposition

2023-02-22

Abstract excerpt

<h4>Purpose: </h4> Mode decomposition is a method of extracting the characteristic intrinsic mode function (IMF) from various multidimensional time-series signals. Variational mode decomposition (VMD) searches for IMFs by optimizing the bandwidth to a narrow band with the norm while preserving the online estimated central frequency. In this study, we applied VMD to the electroencephalogram (EEG) analysis during ge...
