简要总结
The purpose of this study is to compare a 2-lead frontal electroencephalogram recording to a formal polysomnography (PSG) in detecting sleep vs. wake and depth of sleep in both healthy and ICU patients.
详细描述
Sleep in the intensive care unit (ICU) is poor and not well understood. Formal polysomnography (PSG) is the gold standard measure, but impractical for critical care. The relative influence of environment, illness and interventions on sleep in critically ill patients is therefore essentially unknown. Interventions to improve sleep have been pragmatic and outcomes subjective or indirect, and uninformed. When it is done, formal PSG in critical illness demonstrates fragmented, shortened, interrupted and non-circadian sleep, with environmental noise, light, and frequent physical stimulation causing arousals.
