“…Drouot and colleagues devised a new classification for sleep analysis that incorporates visual scoring and spectral analysis of the EEG (21). Two new states of sleep are proposed: pathologic wakefulness and atypical sleep.…”

“…Two new states of sleep are proposed: pathologic wakefulness and atypical sleep. Pathologic wakefulness is determined and graded visually by assessment of the EEG reactivity (21). This method visually examines the background EEG rhythm in the occipital channel while the patient is awake with eyes closed followed by the patient's EEG reactivity to eye opening plus the peak EEG frequency using spectral analysis.…”

“…This method visually examines the background EEG rhythm in the occipital channel while the patient is awake with eyes closed followed by the patient's EEG reactivity to eye opening plus the peak EEG frequency using spectral analysis. Atypical sleep is defined by the absence of K complexes and sleep spindles with the presence of highamplitude, continuous irregular delta frequency EEG without superimposed fast frequencies or rapid eye movements and with low-amplitude chin EMG (21,22). This system was devised in ICU patients who were not on any sedation.…”

“…Such a strategy for sleep analysis expands upon existing strategies using visual inspection and quantitative spectral analysis of EEG. Using this approach in the ICU, atypical sleep was predicted with a sensitivity of 100% and a specificity of 97% (21).…”

Sleep is an important physiologic process, and lack of sleep is associated with a host of adverse outcomes. Basic and clinical research has documented the important role circadian rhythm plays in biologic function. Critical illness is a time of extreme vulnerability for patients, and the important role sleep may play in recovery for intensive care unit (ICU) patients is just beginning to be explored. This concise clinical review focuses on the current state of research examining sleep in critical illness. We discuss sleep and circadian rhythm abnormalities that occur in ICU patients and the challenges to measuring alterations in circadian rhythm in critical illness and review methods to measure sleep in the ICU, including polysomnography, actigraphy, and questionnaires. We discuss data on the impact of potentially modifiable disruptors to patient sleep, such as noise, light, and patient care activities, and report on potential methods to improve sleep in the setting of critical illness. Finally, we review the latest literature on sleep disturbances that persist or develop after critical illness.

“…The distinction between wake and NREM sleep is made by visual analysis of a 30-second portion of an electroencephalogram (EEG): during waking, the EEG shows a mix of fast oscillations (>16 Hz) and alpha rhythm (8)(9)(10)(11)(12) of low amplitudes (<10 mV). During light NREM sleep (stages 1 and 2), the background EEG is characterized by slow theta oscillations (frequency between 4 and 7 Hz) and sleep spindle and K complexes.…”
