How is the increase in fetal umbilical blood pressure caused

Patient's question:

No

Doctor's answer:

Okay, here is the translation following your instructions:
The umbilical cord can be compressed, which may lead to poor umbilical blood flow and cause fetal hypoxia. It's important to get oxygen immediately until the fetal heart rate is normal or fetal movement is normal. Just follow the doctor's instructions for oxygenation and follow-up checks.
