Strategy to Avoid Excessive Oxygen for Critically Ill Trauma Patients

Post-implementation of targeted normoxemia through oxygen titration for individual patients. Interventions for treatment of hypoxemia will follow usual local practice. Interventions for treatment of hyperoxemia (SpO2 \>96% or PaO2 \>100 mmHg) will involve down titration of FiO2 (or supplemental oxygen for non-mechanically ventilated patients) within a time frame based on local site preferences-typically in increments of no greater than 0.10 until goal oxygenation in the normoxemia range is achieved (including room air \[no supplemental oxygen\] for non-mechanically ventilated patients).
