Severe TBI pts require definitive airway protection (risk pulm aspiration, compromised resp drive/fxn)
Normal ventilation (w/ PaCO2 35-45 mmHg) is currently the goal in absence of cerebral herniation
Prolonged prophylactic hyperventilation (PaCO2 ≤25 mmHg) not recommended
Hyperventilation may be used as a temporizing measure to ↓ ICP (ex if cerebral herniation)
