From: Prenatal prediction of neonatal haemodynamic adaptation after maternal hyperoxygenation
Changes in fetal PA PI and PA AT:ET following maternal hyperoxygenation according to gestational age. a Fetal pulmonary artery pulsatility index percentage change in responders and non-responders to maternal hyperoxygenation according to gestational age. b Fetal pulmonary artery acceleration to ejection time ratio percentage change in responders and non-responders to maternal hyperoxygenation according to gestational age. R = 0 represents no correlation with gestational age, p values not significant
