BIS-Guided Sedation Monitoring

This study looks to assess whether monitoring sedation status in mechanically-ventilated Medical Surgical Intensive Care Unit (MSICU) patients using Bispectral index (BIS) monitor-augmented sedation monitoring as opposed to Richmond Agitation Sedation Scale (RASS) score is associated with decreased duration of mechanical ventilation. Investigators hypothesize that using BIS monitors to help monitor depth of sedation in mechanically ventilated ICU patient will result in a decreased duration of mechanical ventilation when compared to solely utilizing clinical sedation scales such as RASS.
