Figure 3.

Correlations between total bilateral intrapulmonary shunting and systemic oxygenation measurements. Figures show XY scatter plots with linear best-fit slopes for (A–C) all patients (n = 72), (D–F) patients with Fontan circulation during testing (n = 23), and (G–I) patients with Glenn or Kawashima circulation during testing (n = 49). r_s indicates Spearman’s rank correlation coefficient. SpO₂—peripheral oxygen saturation, DAo SO₂—descending aorta oxygen saturation, DAo PO₂—descending aorta partial pressure of oxygen.
