Thus the careful study of sleep in the ICU is essential to understanding possible relationships with adverse clinical outcomes. Such research however must be conducted using sleep measurement techniques that have important limitations in this unique setting. Polysomnography PSG is considered the gold standard but is cumbersome time consuming and expensive. As such alternative methods of sleep measurement such as actigraphy processed electroencephalography monitors and subjective observation are often used. Though helpful in some instances data obtained using these methods can often be inaccurate and misleading. Even PSG itself must be interpreted with caution in this population due to effects of critical illness and associated treatments. Heralded as the new frontier in critical care medicine sleep in intensive care unit ICU patients is rapidly gaining attention. Researchers now recognize that ICU patients experience poor quality sleep with severely disrupted sleep architecture. The outcomes attributable to poor sleep quality in the ICU are not yet known
