The effect of maternal short-term inhalation of oxygen (51/min) on intervillous (IVBF) and umbilical vein blood flow (UVBF) was studied in 22 cases during the third trimester of pregnancy. The maternal paO2 levels increased significantly (P less than 0.001) after O2 inhalation. The mean IVBF level was 190 +/- 66 (SD) ml/min per 100 ml of the intervillous space before inhalation and 125 +/- 58 ml afterwards, the decrease being significant (P less than 0.01). UVBF maintained its original level after O2 inhalation. The human fetus seems not to compensate for alterations in oxygen delivery and reduced IVBF after maternal oxygen inhalation, by means of changes in UVBF.
对22例妊娠晚期孕妇进行研究，观察母体短期吸入氧气（5升/分钟）对绒毛间隙血流（IVBF）和脐静脉血流（UVBF）的影响。吸氧后母体动脉血氧分压（PaO2）水平显著升高（P<0.001）。吸入前每100毫升绒毛间隙的平均IVBF水平为190±66（标准差）毫升/分钟，吸入后为125±58毫升/分钟，下降显著（P<0.01）。吸氧后UVBF维持原有水平。母体吸氧后，人类胎儿似乎无法通过改变UVBF来代偿氧输送的变化和IVBF的降低。
