Pregnant women can start using a fetal heart rate monitor from 12 weeks. This is because the fetus has not yet moved, so it is best to use a Doppler fetal heart rate monitor once a day. In the second trimester, the fetus has fetal movement, and the mother can combine it with the fetal movement. If the fetal movement is more regular, the fetal heart rate monitor can be used every two or three days.
After 4 months of pregnancy, it is generally necessary to listen to the fetal heart rate every time you go to the hospital for a prenatal check-up. Prenatal check-ups are generally once a month. After 37 weeks of pregnancy, you need to go to the hospital for fetal heart monitoring once a week. The fetal heart rate is 120 to 160 beats per minute. If the fetal heart rate is too fast or too slow, it may indicate that the fetus is hypoxic in the uterus, and it is necessary to listen to the fetal heart rate again.
When it comes to the third trimester, the fetus is relatively large, and pregnant women are prone to umbilical cord around the neck, respiratory distress, fetal intrauterine hypoxia and other conditions. It is best to use the fetal heart rate monitor 2-3 times a day, or use the fetal heart rate monitor at any time when you feel uncomfortable.
1. The number of times to monitor the fetal heart rate every day is not absolute. It depends on the stage of pregnancy. Moreover, the situation of each pregnant woman is different, and the number of times is also different.
2. Generally, pregnant women can use the fetal heart rate monitor from the twelfth week, but the baby has no fetal movement at this time, so it is necessary to monitor at least once a day. After the twelfth week, if the baby's fetal movement is more regular, it is appropriate to monitor once every two to three days.
3. In the late pregnancy, the baby is prone to intrauterine hypoxia caused by the umbilical cord around the neck. Therefore, you should understand the baby's condition every day. If the heartbeat is weak, you should seek medical attention in time. If your baby has stopped having fetal heartbeat, it is best to monitor more times a day.
