At how many weeks of pregnancy can I use a fetal heart monitor

The fetal heart rate is relatively important for the fetus. If the fetal heart rate develops normally, it can ensure the normal development of the fetus. Many pregnant women use fetal heart monitors to measure the fetal heart rate during pregnancy. Of course, the fetal heart monitor cannot be used at any time, and many pregnant women are afraid to use it because they are worried about the radiation from the fetal heart monitor. Next, I will introduce you to some relevant knowledge about fetal heart rate monitoring!

1. At how many weeks of pregnancy can I use a fetal heart monitor?

1. Generally, the fetal heartbeat can be heard after 12 weeks of pregnancy. Before 12 weeks of pregnancy, it can only be detected by B-ultrasound. After 12 weeks of pregnancy, the fetal heartbeat may be strong or weak, which is related to the development of the fetus.

2. It is recommended to use a Doppler fetal heart monitor to monitor the fetal heart rate after 12 weeks. It is also recommended to cooperate with B-ultrasound to observe the condition of the child, etc. In addition, you need to pay attention to nutritional supplements and rest on time!

2. Does the fetal heart monitor have radiation?

1. The fetal heart monitor uses the principle of ultrasound to collect the heartbeat information of the fetus. It does not emit any radiation signals or any radiation. Now we advocate more scientific fetal home monitoring, the main content of which is to use a fetal heart monitor three times a day, morning, noon and evening, each time for 2 to 3 minutes, to monitor whether the fetal heart rate is within the normal range: 120 to 160 beats per minute, so as to understand the health of the fetus.

2. If you have enough time, you can also monitor the correlation between fetal heart rate and fetal movement changes at home to understand the fetus's reserve function. The market has recently launched a fetal talker that is more intuitive and can help expectant mothers detect the health of the fetus. It can draw the fetal heart rate curve and record fetal movements on smart terminal devices, making it easier to analyze the health of the fetus.

3. Does the fetal heart rate monitor have any effect on the baby?

The fetal heart monitor mainly uses ultrasonic detection technology to complete fetal heart rate detection. Its function is to reflect the condition of the fetus in the mother's body by monitoring fetal movement and fetal heart rate. Pregnant mothers can roughly judge the health status of the fetus based on the data displayed on the fetal heart monitor. Regarding pregnant mothers' concerns that the sound waves of fetal heart monitors will affect the fetus, experts explained, "Sound waves are a physical factor, a kind of energy, and there is a question of safe dose. Whether ultrasound is harmful or harmless to the human body or the fetus depends on the dose of ultrasound. When the dose of ultrasound used is less than this value, it is harmless." The ultrasound dose of fetal heart monitors is far below the safety index requirements, so it generally does not affect the fetus.

However, expectant mothers need to note that it is not appropriate to listen to the fetal heart rate too frequently during pregnancy, otherwise it will affect the normal rest of the fetus.
