I believe many female friends pay close attention to the development of their baby during pregnancy, and it is necessary to undergo various examinations on time at this time. During this period, everyone should also pay attention to the fetal heart rate and promptly go to the hospital for fetal heart rate monitoring. So, what should we do with fetal heart rate monitoring?
The occurrence of positive waves in fetal heart monitoring is serious and poses a threat to the life of the fetus. Zhengxuan wave is a smooth, sine wave like oscillation of fetal heart rate baseline, with a fixed frequency of 3 to 5 beats per minute and a duration greater than 20 minutes. It belongs to the third category of electronic fetal heart rate monitoring. The Zhengxuan wave pattern indicates the presence of acid-base imbalance and fetal hypoxia in the fetus. Immediate measures should be taken to correct fetal hypoxia, including changing the pregnant woman's position, administering oxygen, stopping the use of oxytocin, inhibiting uterine contractions, and correcting maternal hypotension. If fetal heart monitoring does not improve after these measures, active surgical termination of pregnancy should be performed.
If the pregnant woman is healthy during pregnancy, does not suffer from diabetes, hypertension and other diseases, and the various indicators of the fetus and baby are also normal, the fetal heart rate monitoring is generally carried out at 36 weeks of pregnancy. If there are no abnormalities in the fetus, pregnant women can undergo fetal heart rate monitoring once a week.
If a pregnant woman has symptoms such as high blood pressure, or if there is poor fetal development, such as inadequate fetal height and weight, or intrauterine growth restriction, fetal heart rate monitoring should be carried out from around 30 weeks, and the pregnant woman should regularly monitor the fetal heart rate every day.
