|Full Title||Acute Lung Injury Ventilator Evaluation (ALIVE) Trial: Biomarkers of Lung Injury With Low Tidal Volume Ventilation Compared With Airway Pressure Release Ventilation in Trauma Patients|

This study will compare two ventilator modes in mechanically ventilated patients with acute lung injury.
Acute lung injury (ALI) is a condition in which the lungs are badly injured and are not able to absorb oxygen the way healthy lungs do. About 25% of patients who are ventilated get ALI. ALI causes 75,000 deaths in the US each year.
Ventilators can be set to work in different ways, called modes. One mode, called ARDSNet, pumps a small amount of air into the patient’s lungs and then most of the air is released prior to the next breath. Another mode, called Airway pressure release ventilation (APRV), keeps air in the lungs longer between breaths. Both of these modes are currently used at this hospital. The investigators think APRV may help patients with ALI, but we do not know for sure.
