FIGURE 1
Distribution of observed and predicted SO2 values in COVID‐19 patients. (A) SO2 is reported as a function of observed PaO2. and (B) as a function of PaO2 corrected for arterial blood pH and PaCO2. Red marks represent the expected SO2 value for any given PaO2 according to Doyle equation; blue dots correspond to experimental data.
