From: Peak and averaged bicoherence for different EEG patterns during general anaesthesia
Examples of EEG states relating to deepening sedation. Ranging from awake (states 1 - 4) to burst suppression (state 10). The raw EEG is recorded via ASCII protocol from the BIS unit. These are typical examples from the current dataset and therefore from an anaesthetic regimen of bolus induction (either propofol or thiopentone) and inhalational maintenance (sevoflurane, isoflurane or desflurane).
