Sedated mechanically ventilated patients

Detailed Description:
This is a single center, observational, cross-over design study assessing the impact of daily awakening from sedation on delirium in the ICU. Enrolled patients will receive a daily baseline delirium assessment using the CAM-ICU tool before the awakening from sedation and an assessment during the awakening from sedation. Each patient will thus serve as their own controls for these interventions.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
