Fetal heart rate monitoring is an important examination for expectant mothers in late pregnancy. During this period, the fetus has limited space for movement and is prone to hypoxia. Therefore, in order to ensure the healthy growth of the fetus, fetal heart monitoring must be done well. So what is the reason for stable fetal heart rate in fetal heart monitoring?
The normal baseline fetal heart rate is between 120 and 160 beats per minute, and as the fetus moves, an increase in fetal heart rate can be observed. The duration should be greater than 15 seconds, and the rise rate should be greater than 15 times per minute. During a 20 minute fetal heart rate monitoring, there should be 3 to 5 fetal movements and corresponding acceleration reactions. If the fetal heart rate monitoring is stable, that is, there is no fetal movement during the monitoring time or the fetal heart rate does not increase after fetal movement. This may indicate that the fetus is in a sleep period, or it may indicate poor placental function and fetal intrauterine distress.
If there is a fetal heart rate test and it is found that the fetal heart rate is stable only once or twice, then there is no need to worry too much, it may be because the baby is sleeping. However, it should be noted that there are many stable fetal heart rates detected during fetal heart rate testing, which is often caused by hypoxia. Therefore, pregnant women should receive timely oxygen therapy.
Pregnant women should also pay attention to rest well and avoid vigorous exercise. When undergoing fetal heart rate testing, pregnant women should also control their emotions and not be too nervous. If they are in an anxious state for a long time, it will be even more detrimental to the growth of the fetus.
