Utility of Pulse Oximetry Oxygen Saturation (SpO₂) with Incorporation of Positive End-Expiratory Pressure (SpO₂10/FiO₂PEEP) for Classification and Prognostication of Patients with Acute Respiratory Distress Syndrome

Figure 3

Receiver operating characteristic curves to predict survival for P/FP10 and S/FP10 at baseline, day 1, and day 3. The P/FP10 (D3) has an AUC of 0.900 and a cut-off ≥257.5 to predict survival, followed by S/FP10 (D3) with a cut-off ≥243.75 and an AUC of 0.872.
