Can state or response entropy be used as a measure of sleep depth?

Can state or response entropy be used as a measure of sleep depth?

Summary In this prospective observational study we examined the potential of the spectral entropy measures ‘state’ and ‘response’ entropy (Entropy™ monitor), as measures of sleep depth in 12 healthy adult subjects. Both median state and response entropy values varied significantly with sleep stage (...

Zusammenfassung:Summary In this prospective observational study we examined the potential of the spectral entropy measures ‘state’ and ‘response’ entropy (Entropy™ monitor), as measures of sleep depth in 12 healthy adult subjects. Both median state and response entropy values varied significantly with sleep stage (p = 0.017 and p = 0.014 respectively; ANOVA). Median state or response entropy did not decrease significantly during the transition from awake to stage I sleep (p > 0.017). State entropy values decreased significantly between sleep stages I and II (p
