Key Points Question Can the prehospital ratio of oxygen saturation measured by pulse oximetry (Sp o 2 ) to fraction of inspired oxygen (F io 2 ) be used to model early in-hospital mortality? Findings Data from 3606 patients were analyzed in a prognostic study. The Sp o 2 to F io 2 ratio had a statistically significant area under the curve of 0.890 for the prediction of 2-day mortality. Meaning This study suggests that the prehospital Sp o 2 to F io 2 ratio allows for the identification of patients at risk of in-hospital deterioration.
