Extract
Sleep is markedly altered in intensive care unit (ICU) patients under mechanical ventilation [1–4]. Sleep in these patients is fragmented by numerous arousals and awakenings and mainly comprises light sleep. The deep sleep allowing physical restoration and the rapid eye movement (REM) sleep allowing neurobehavioral restoration may completely disappear. In some ICU patients, normal sleep architecture may disappear and be replaced by electroencephalogram aspects suggesting atypical sleep [5–7]. Whereas it has been shown that sleep deprivation could alter physical and cognitive functions in animals [8], the potential deleterious effects of such sleep disturbances in critically ill patients are unknown.
Abstract
A strong relationship might exist between sleep and weaning from mechanical ventilation in the ICU, and sleep alterations may be an underexplored aspect of weaning difficulties http://ow.ly/TzQq30ktNB5
