By means of tcPO2 measurement, a total of 297 FHR accelerations from 55 oxygen cardiotocograms were analysed with regard to their association with changes in fetal oxygen pressure sub partu. It could be demonstrated that the transcutaneous oxygen pressure of 2.3 kPa (17.1 mmHg) with occasional accelerations was significantly (alpha less than 0.05) higher than that of 2.2 kPa (16.6 mmHg) with periodic accelerations. Oxygen pressure with occasional accelerations with "classical parameters" (amplitude greater than or equal to 15 bpm, duration greater than or equal to 15 sec) did not significantly differ from that with one or both parameters below these minimal values. Furthermore, our results suggest the production of periodic accelerations by pressorreceptor reflex due to intermittent disturbance in umbilico-placental perfusion.
通过经皮氧分压（tcPO2）测量，对来自55份氧合胎心监护图的总共297次胎心率加速进行了分析，以研究它们与分娩期胎儿氧压变化的关联。结果表明，伴有偶尔加速的经皮氧分压2.3 kPa（17.1 mmHg）显著（α<0.05）高于伴有周期性加速的2.2 kPa（16.6 mmHg）。伴有“经典参数”（振幅≥15次/分钟，持续时间≥15秒）的偶尔加速的氧压与一个或两个参数低于这些最小值时的氧压没有显著差异。此外，我们的结果提示，由于脐-胎盘灌注的间歇性干扰，压力感受器反射导致了周期性加速的产生。
