Overview
Brief Summary
The purpose of this study is to collect physiologic data from patients with severe brain injury who require mechanical ventilation in order to describe the impact of ventilation, specifically positive end expiratory pressure (PEEP), on intracranial pressure (ICP).

Eligibility Criteria
Inclusion Criteria
- •Patients with severe brain injury (GCS 8 or less)
- •Receiving mechanical ventilation
- •Receiving intracranial pressure monitoring
Exclusion Criteria
- •Esophageal varices
- •Esophageal trauma
- •Recent esophageal surgery
- •Coagulopathy (Platelets \< 80k or INR\> 2 )
- •Other contraindication for esophageal manometry
- •Already receiving PEEP \> 15 cmH2O at enrollment

Outcomes
Primary Outcomes
Association between PEEP and ICP
Time Frame: Change from baseline to 20 minutes
Intracranial pressure will be measured and recorded using the existing intracranial pressure monitoring device placed previously as part of the patient's routine care. The association between positive end expiratory pressure and intracranial pressure will be analyzed as the primary outcome.
Secondary Outcomes
- Association between transpulmonary pressure and ICP(Change from baseline to 20 minutes)
- Association between PEEP and cerebral hemodynamics(Change from baseline to 20 minutes)
