Fetal heart monitoring, a fetal heart rate between 110-160 beats per minute is considered normal. After 32 weeks of pregnancy, it needs to be done once a week and the fetal heart monitoring needs to be done for 20 minutes. If the fetal heart rate is normal and the variation is good, it indicates that the fetus will not have abnormalities within 1 week. If the fetal heart rate is normal and the variability is good, it means that the fetus will not have any abnormality within 1 week. When doing fetal heart monitoring, not only the variability of the fetal heart rate should be observed, but also the variability of the baseline should be within the normal range. If the fetal movement is too fast or too slow, the woman should use the left-sided position and oxygen to improve the situation. If this is not relieved, an obstetric ultrasound should be performed to prevent fetal distress. Fetal heart monitoring is a clear indicator of fetal growth and development in the uterine cavity in the late stages of pregnancy.
