Mortality Prediction Using SaO₂/FiO₂ Ratio Based on eICU Database Analysis

Figure 3

SHAP table demonstrating feature importance ranked in descending order on y-axis. x-axis with the SHAP values. Negative SHAP value predicts a low probability of death at a high or low value of that feature value (blue = low value; red = high value). Positive SHAP value demonstrates a high probability of mortality at that feature value. Low S/F values (blue) predict a high likelihood of death, whereas high values (red) predict a low likelihood. PaO₂: partial pressure of oxygen; FiO₂: fraction of inspired oxygen; SaO₂: oxygen saturation; P/F: PaO₂ and FiO₂ ratio; S/F: SaO₂ and FiO₂ ratio; S/F: SaO₂/FiO₂, P/F: PaO₂/FiO₂; Vent: mechanical ventilation.
