Patient's question:
I am 38 weeks pregnant and had an antenatal check-up where they said the fetal heart monitoring was not qualified and I always had to breathe oxygen. However, I didn't feel any discomfort in my body. Breathing oxygen every day is very uncomfortable because the tube is inserted into my nose, which feels very unpleasant. But I don't know how to read the fetal heart monitoring chart and don't understand where the problem is.What kind of help do I need: How to read the fetal heart monitoring chart?
Doctor's answer:
，，120－160，（20），（160-180/），，。，5-25/，3-8，。，，160/，，。160，120，，，，。，，20mmHg。In fetal heart monitoring, there are mainly two lines. The upper one represents the fetal heart rate, which normally fluctuates between 120 and 160 beats per minute. When the fetus is smaller (less than 20 weeks), the heart rate is relatively faster (it can be between 160 and 180 beats per minute). When the fetus is larger, the heart rate is relatively slower. The difference between each heartbeat is called short-term variability, with a normal range of 5 to 25 beats per minute. The fetal heart rate has 3 to 8 larger fluctuations per minute, which is normal short-term variability. However, after fetal movement, the heart rate may briefly increase and exceed 160 beats per minute, but then quickly return to normal. This indicates that the fetus is in good health. If the fetal heartbeat exceeds 160 beats per minute per minute, is less than 120 beats per minute, or is irregular (with rapid and slow intervals, or intermittent gaps), it is considered abnormal. The lower line represents intrauterine pressure, which only increases during contractions and then remains around 20 mmHg.
