Study Arms:
- Airway Pressure Release Ventilation:APRV (Type: None): Each participant will serve as his/her own control using our observational crossover study comparing the effects of Airway Pressure Release Ventilation and Low Tidal Volume Ventilation on patient intracranial pressure and hemodynamic values.
- Low Tidal Volume Ventilation:LOTV (Type: None): Each participant will serve as his/her own control using our observational crossover study comparing the effects of Airway Pressure Release Ventilation and LOTV on patient intracranial pressure and hemodynamic values.

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