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 4

The ROC of the change in the P/FP10 and S/FP10 ratios from baseline and day one to day three to predict survival. The AUC of the P/FP (D3-B) is the highest (AUC: 0.902, cut-off ≥34.25), followed by the AUC of S/FP (D3-B) (AUC: 0.877, cut-off ≥64.40).
