How to monitor fetal heart rate during pregnancy

Pregnant women will undergo many tests to determine the development of the fetus and understand the condition of the fetus. These examinations include fetal heart rate monitoring. Fetal heart rate monitoring is a test conducted by the hospital on the fetal heart rate of pregnant women. It has no major impact on the fetus. In addition to testing the fetal heart rate, pregnant women will also undergo various B-ultrasound and color ultrasound tests. Below we will tell you some content and issues about fetal heart rate monitoring during pregnancy.

What is fetal heart rate monitoring?

Fetal heart rate monitoring is the abbreviation of fetal heart rate, fetal movement and uterine contraction chart. It is a graph that uses an electronic fetal heart rate monitor to record the fetal heart rate curve and uterine contraction pressure waveform for clinical analysis. It is the main detection method for correctly evaluating the condition of the fetus in the uterus. Using microwave technology, no harm to the fetus.

What does fetal heart rate monitoring check?

Fetal heart rate monitoring is regulated by the sympathetic and parasympathetic nerves. By recording the instantaneous changes in the fetal heart rate through the curve of the monitoring graph, we can understand the reaction of the fetal heart rate during fetal movement and uterine contraction, so as to infer whether the fetus in the uterus is suffering from hypoxia. In a normal pregnancy, fetal heart rate monitoring should be performed once a week starting from the 37th week of pregnancy. If there are comorbidities or complications, it can be performed from the 28th to 30th week of pregnancy. Attention should be paid to whether the rhythm of the fetal heart rate is fast or slow. The normal fetal heart rate is 120 to 160 beats/minute. If the fetal heart rate is above 160 beats/minute or lasts for 100 beats/minute, it indicates intrauterine fetal hypoxia and should be treated promptly.

What is the normal fetal heart rate?

The normal fetal heart rate is strong and powerful, at 120-160 beats per minute, with a regular rhythm and moderate strength, like the "ticking" sound of a clock. The fetal heart rate may increase by 10 to 20 beats per minute when the fetus moves. If the heart rate is continuously higher than 160 times/minute or lower than 110 times/minute, it is abnormal.

If the expectant mother is nervous or tired, it may cause a faster fetal heart rate. At this time, lying on the left side can alleviate the phenomenon of a fast fetal heart rate. If it is still too fast, you should consider whether the fetus is suffering from intrauterine hypoxia. It is best to consult a doctor for advice.

The above is the relevant content about fetal heart rate monitoring for pregnant women. Fetal heart rate monitoring can help us understand the fetal movement, as well as the fetal development and health status in the mother's body. For many people, fetal heart rate monitoring is convenient and reliable. It has gradually become a must-do examination for pregnant women. Currently, there are many home fetal heart rate monitoring methods that are simple and convenient.
