When Is The Best Time To Use A Doppler Fetal Heart Rate Monitor?

If the fertilized egg implants in the female uterus, the woman will experience morning sickness and other symptoms. It takes about ten months for a woman to give birth to a baby. The fetus will have a fetal heartbeat at about three months. If you go to the hospital for a check-up at this time, the doctor will use the fetal heartbeat to determine whether the baby is healthy. When should the fetal heart rate monitor be used?
1. The Doppler fetal heart rate monitor is generally used at 12 weeks of pregnancy. At this time, because the uterus is enlarged beyond the pelvic cavity, the fetal heartbeat can be heard above the pubic symphysis. During each prenatal examination, the doctor will listen to the fetal heartbeat in the pregnant woman's abdomen. The normal value is 110 to 160 times per minute. Some pregnant women will have a home fetal heart rate monitor at home, and they can self-test the fetal heartbeat after 12 weeks of pregnancy. If the fetal heartbeat is too fast or too slow, you need to see an obstetrician and gynecologist, and if necessary, an obstetric B-ultrasound examination to understand the status of the fetus in the uterus.
2. Under normal circumstances, during pregnancy, before 15 weeks of pregnancy, ultrasound Doppler fetal heart rate monitors are not used for self-monitoring. For pregnant women between 15 and 28 weeks of pregnancy, it is safe to measure 3 times a day for 1 minute each time. For pregnant women after 28 weeks of pregnancy, the fetus is fully differentiated, and the monitoring time and frequency can be extended. For high-risk pregnant women after 35 weeks of pregnancy (for example, pregnant women with gestational hypertension, hyperthyroidism, etc.), they should be hospitalized and continuously monitor the fetal heart rate with a fetal heart monitor. If necessary, continuous monitoring can be performed for a long time (more than 1 hour).
3. Expectant mothers can hear the fetal heart rate with a fetal heart monitor, and can use the fetal heart monitor at home to monitor fetal heart rate changes, and can also count fetal movements. If the fetal heart rate and fetal movements are normal, there is no need to worry. Usually pay attention to strengthening nutritional balance, eat more meat and vegetables to supplement nutrition, and go to the hospital for regular prenatal check-ups to confirm that the fetus is developing normally.
