Eskesen TG, et al. - In this prospective, observational study of trauma patients ≥16 years of age, researchers determined the use of supplemental oxygen and occurrence of hyperoxemia in the initial phase of trauma management at two level 1 trauma centers, TC1 and TC2. They analyzed data on pre- and in-hospital supplemental oxygen, arterial oxygen tension (PaO₂), and outcomes (in-hospital mortality, hospital- and intensive care unit length of stay). They noted that, the initial treatment was accompanied with the receipt of supplemental oxygen in approximately 50% of trauma patients. In patients treated with supplemental oxygen, the occurrence of hyperoxemia was commonly detected. Its occurrence was more pronounced in intubated patients.
