Trial Title: Correlation of Cerebral State Index With the Richmond Agitation-Sedation Scale in Mechanically Ventilated ICU Patients

Study Design Characteristics:
- Allocation: None
- Intervention Model: None
- Observational Model: CASE_ONLY
- Primary Purpose: None
- Time Perspective: PROSPECTIVE
- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria:~* Admission the surgical-trauma intensive care unit at the Charleston Area Medical Center General Hospital~* Adult (18-85 years of age)~* Anticipated duration of mechanical ventilation of at least 72 hours~Exclusion Criteria:~* Patients admitted with paralysis or a brain injury~* Patients who are deaf, blind, or have pre-existing dementia/delirium

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 85 Years
- Healthy Volunteers: f

Study Arms:
- Cerebral State Monitor (Type: None): A cerebral state monitor will provide a cerebral state index for mechanically ventilated intensive care patients. Recorded cerebral state indexes will be correlated with clinical assessments of sedation using the Richmond Agitation-Sedation Scale.

Based on this trial design, predict the completion outcome and termination type (if applicable).
