Fetal heart monitoring is usually started after 32-34 weeks of gestation, and is recommended after 30 weeks for high-risk pregnancies to assess the status of the fetus in utero. Fetal heart monitoring is performed every 2 weeks before 36 weeks of gestation and once a week after 36 weeks of gestation. The frequency of fetal heart monitoring will also be increased according to the situation after regular contractions occur in pregnant women before delivery. By continuously observing and recording the dynamic changes of fetal heart rate, fetal heartbeat, fetal movement and contractions are understood in relation to each other, so as to assess the fetal well-being. The normal fetal heart rate is 110-160 beats per minute. If the fetal heart rate is abnormal, the fetal heart rate may need to be monitored again after the mother has been placed on her left side to receive oxygen. Before the fetal heart monitoring, the pregnant woman can gently rub her abdomen and eat some food half an hour before the examination to encourage the fetal baby to move around. When performing fetal heart monitoring, pregnant women should choose a comfortable position. Pregnant women should pay attention to the number of fetal movements and seek medical attention for fetal heart monitoring if they feel a decrease in fetal movements or if they have abnormalities such as vaginal bleeding. If the pregnancy cannot continue normally, a cesarean section should be performed in time to terminate the pregnancy.
