Doppler Fetal Heart Rate Can Detect Twins

Fetal Doppler can monitor fetal movement and fetal heart rate to reflect the condition of the fetus in the mother’s body. After 35 weeks of pregnancy, pregnant women should perform fetal heart rate monitoring when they go to the hospital for an obstetric examination every week. However, this can only be monitored at a specific time period and cannot be monitored as needed, so expectant mothers are also required to develop the habit of detecting fetal movement by themselves every day.

Can Fetal Doppler Detect Twins?

Yes, because Doppler fetal heart rate is judged by detecting fetal heart sounds, so it can detect twins or multiples, which is a very useful monitoring instrument.

What is the principle of Doppler fetal heart rate?

Doppler fetal heart rate monitor is mainly an electronic instrument used for fetal heart rate monitoring. Generally, maternity hospitals provide fetal heart rate monitoring. The Doppler fetal heart rate monitor is more commonly used in the market, and the ultrasound Doppler technology is mostly used, and the ultrasound dose is small. The Doppler fetal heart rate meter calculates the number of heartbeats in each cardiac cycle of the fetal heart rate, and traces it on the chart in turn to show the baseline variation of the fetal heart rate. Within a certain range, the baseline change of fetal heart rate indicates the establishment of central N autonomic regulation and cardiac conduction function in the fetal heart, and the fetal heart rate has a certain reserve capacity.

Fetal heart monitoring is carried out by two probes tied to the expectant mother, one is tied to the top of the uterus, which is a baroreceptor, and its main function is to know whether there are uterine contractions and the strength of uterine contractions; the other is placed on the fetus’s chest or On the back, the fetal heart rate was measured. The screen of the instrument has the corresponding graphic display of fetal heartbeat and uterine contractions, and expectant mothers can clearly see their baby’s heartbeat. There is also a button, when the expectant mother feels the fetal movement, she can press this button, and the machine will automatically record the fetal movement.
