Oxygen therapy has undisputed importance in the care of critically ill patients to prevent secondary complications related to hypoxemia. Although routine, the practice of excessive over-oxygenation may be harmful. An expert panel was convened and developed the strong consensus to target normoxemia at an oxygen saturation (SpO2) range of 90-96%, an arterial oxygen (PaO2) range of 60-100 mmHg (when applicable), and a fraction of inspired oxygen (FiO2) of 21% for mechanically ventilated patients or room air for nonmechanically ventilated patients.
Specific Aim: The purpose of this study is to determine the effectiveness of a multimodal educational intervention to reduce supplemental oxygen use in critically injured patients. Investigators will also evaluate the safety and clinical effectiveness of the more targeted use of oxygen therapy.
Hypotheses: Clinical efforts to through a multimodal educational intervention will:
1. Improve the proportion of time spent within target normoxemia thresholds (oxygen saturation \[SpO2\] 90-96% and/or arterial oxygen \[PaO2\] 60-100 mmHg \[when applicable\]
2. Limit use of excessive supplemental oxygen
3. Reduce exposure to hyperoxemia without a substantive increase in hypoxemic episodes or adverse effects
