Sleep Fragmentation Indices as Predictors of Daytime Sleepiness and in nCPAP Response in Obstructive Sleep Apnea

摘要

Sleep fragmentation and respiratory disturbance measures are used in the assessment of obstructive sleep apnea(OSA) but have proved to be disappointingly poor correlates of daytime sleepiness. This study investigates the ability of electroencephalograph(EEG) and non-EEG sleep fragmentation indi- ces to predict both presenting sleepiness and the improvement in sleepiness with subsequent nasal continuous positive airway pressure(nCPAP) therapy(nCPAP responsive sleepiness).
