Maternal hyperoxia is associated with increased fetal oxygenation. Scatter plots showing the extent of increase in fetal PaO₂ (A) and oxygen content (B) after maternal hyperoxia with 100% oxygen for 6 h. Data are presented as mean ± S.E.M and analyzed with Welch’s t-test; *p ≤ 0.05 and **p ≤ 0.01 (n = 3 per treatment condition).
