The ROX index as a predictor of standard oxygen therapy outcomes in thoracic trauma.

Background: Thoracic trauma is commonplace and accounts for 50-70% of the injuries found in severe trauma. Little information is available in the literature as to timing of endotracheal intubation. The main objective of this study was to assess the accuracy of the ROX index in predicting successful standard oxygen (SO) therapy outcomes, and in pre-empting intubation.
