Thirty-one pregnant women divided into three groups (AGA prepartum, SGA prepartum without distress, AGA in labor) were examined using Doppler ultrasonography before, during and after oxygen administration to mothers via a face mask. The aim of the study was to find out if there was any effect on the blood flow values in the fetal aorta, the umbilical artery, the fetal common carotid artery and the uterine arcuate arteries. The resistance index (RI) did not change in those vessels during maternal hyperoxygenation with one exception: in the group of SGA fetuses the RI in the fetal aorta increased significantly. Blood flow velocity and volume blood flow remained unchanged in the fetal aorta during oxygen administration.
31名孕妇被分为三组（产前适于胎龄儿、产前小于胎龄儿且无窘迫、产时适于胎龄儿），通过面罩给母亲吸氧前、吸氧期间和吸氧后，使用多普勒超声对她们进行检查。该研究的目的是确定对胎儿主动脉、脐动脉、胎儿颈总动脉和子宫弓形动脉的血流值是否有任何影响。在母体高氧期间，这些血管中的阻力指数（RI）没有变化，但有一个例外：在小于胎龄儿组中，胎儿主动脉的RI显著增加。吸氧期间胎儿主动脉的血流速度和血流量保持不变。
