1. Fetal bypass was established with centrifugal pump at the placental group, and bypass of oxygenator group was established with centrifugal pump and oxygenator.
胎盘组运用离心泵和胎盘建立体外循环；人工肺组运用离心泵和人工膜肺建立体外循环，转流中旷置胎盘。
2. We found the pump oxygenator to be extraordinarily efficient, reliable, of great capacity and also simple to operate.
我们发现这个泵氧合器非常有效、可靠、容量大、操作简单。
3. Methods Eight fetal lambs which weighted 12 kg ± 03 kg had undergone cardiopulmonary bypass with artificial oxygenator and roller pump for one hour.
方法8头胎羊（体重12kg±03kg）运用人工氧合器和滚轴泵建立体外循环，转流60min。

5. Two groups of 15 patientsunderwent BHS during normothermia with assistance of two differentSBS consisting of only blood pump and oxygenator.
另两组各15例病人在两种不同的仅包括血泵和氧合器的 SBS 辅助下常温行 BHS 。
