Several evidences in the literature suggest sleep interruption in critical care patients. Nowadays, the amount and the quality of sleep phases during the length of stay in the intensive care unit are largely unknown. In this study, the amount of time spent by the patients in N1, N2 N3 and REM phases during sleep is quantified.
Study Type
OBSERVATIONAL
Enrollment
72
Patients are observed through a Sleep profiler, routinely used in the intensive care unit (ICU). This device is applied at every patient in the ICU and it acquires EEG, electrooculography, and electromyography from three frontopolar EEG signals.
