Issues regarding patient populations monitoring duration and timing nocturnal versus continuous as well as practical problems encountered in critical care studies using polysomnography are considered with regard to future interventional studies on sleep. Polysomnography is the gold standard in objectively measuring the quality and quantity of sleep. However it is difficult to undertake particularly in patients recovering from critical illness in an acutecare area. Therefore other objective actigraphy and bispectral index and subjective nurse or patient assessment methods have been used in other critical care studies. Each of these techniques has its own particular advantages and disadvantages. We use data from an interventional study to compare agreement between four of these alternative techniques in the measurement of nocturnal sleep quantity. Recommendations for further developments in sleep monitoring techniques for research and clinical application are made. Also methodological problems in studies validating .
