Abstract
The effect of posture on maternal capillary blood Po(2) and Pco(2) was studied in pregnant and non-pregnant women. There was a significant decrease of Po(2) (mean 13.0 mm. Hg) and significant decrease of Pco(2) (mean 2.4 mm. Hg) when pregnant women sat up, but these changes did not occur in the non-pregnant. These findings may be relevant to debate on the optimum posture for labour.
摘要
研究了姿势对孕妇和非孕妇母体毛细血管血中氧分压（Po₂）和二氧化碳分压（Pco₂）的影响。孕妇坐起时，氧分压显著下降（平均13.0毫米汞柱），二氧化碳分压也显著下降（平均2.4毫米汞柱），但非孕妇未出现这些变化。这些发现可能与关于分娩最佳姿势的争论有关。
