WebOct 1, 2009 · Abstract Comparison of entropy (state entropy [SE] and response entropy [RE]) with the bispectral index (BIS) during propofol sedation in monitored anaesthesia care (MAC) was carried out in patients undergoing hand surgery. Thirty candidates for elective hand surgery were pre-medicated with midazolam 0.06 mg/kg and atropine 0.01 mg/kg. … WebJan 20, 2024 · The power spectrum of the EEG indicates the power of each frequency component present in the source time domain waveform. For individual time epochs derived from EEG Signals, BIOPAC’s AcqKnowledge software estimates the power spectrum of that epoch to extract mean power, median frequency, spectral edge, and peak frequency.
