During my bachelor’s thesis I examined if EEG markers could serve as a real-time index of consciousness for patients undergoing propofol-sedated endoscopy.
- These features were compared with clinician annotations (including RASS) using ROC/AUC analysis to identify the most discriminative markers.
- Band-limited amplitudes—especially within the β range, with α supporting transitions between relaxed wakefulness and light sedation—proved most informative, whereas phase-synchronisation metrics generalised poorly across subjects.
The results support multi-feature, personalised approaches for closed-loop sedation monitoring and highlight the need for larger, standardised corpora.
