Design outcomes

Primary

MeasureTime frame
To determine the prevalence of sleep deprivation (total sleep time less than 7 hours with Arousal index more than 20 per hour). To determine patterns of sleep disturbances such as changes in sleep stages (N1, N2, N3, REM), wakefulness after sleep onset (WASO), sleep efficiency, sleep onset latency, day time sleep, total sleep (consist of any sleep stages) in 16-24h. Timepoint: Day 2 of ICU admission for 16-24 hours Day 5-7 of ICU admission for 16-24 hours

Secondary

MeasureTime frame
To assess subjective sleep quality using Richard Campbell Sleep Questionnaire (RCSQ). To compare objective polysomnography (PSG) findings with subjective questionnaire responses. To assess the temporal change in the sleep patterns over time. Association of sleep patterns with pain (VAS scores) & ICU delirium (CAM ICU scores). To understand micro-sleep architecture patterns (i.e., EEG spectral patterns, spindle parameters, slow wave parameters, slow-wave-spindle coupling & REM pattern analysis. Timepoint: Day 1-7 of ICU admission
