Frequently Asked Questions and Precautions

What does a fetal heartbeat sound like?
The fetal heart sound is like a "choo-choo-choo", similar to that of a small train or a horse's trot ("da-da-da"), with a very constant and defined rhythm.

Why is it necessary to move the position probe?
Because the fetus is constantly moving inside the uterus, the position of its heart also changes. If the heartbeat is not clearly audible or is very weak, you should gently move the probe until you find the spot where the sound is clearest.

How often can the test be done? Can it affect the baby if it's done too often?
The device's fetal heart rate and other indicators meet national safety standards. You can use it with confidence to monitor fetal heart rate daily. Under normal conditions, it is recommended to measure two to three times a week. Pregnant women of advanced age or with a history of miscarriage can increase the frequency of use if desired.

How do you find the fetal heartbeat correctly?
To locate the heartbeat, move the probe slowly and within a small range (approximately one centimeter) and hold it at each point for two or three seconds. It's important to be patient, as moving the probe too quickly can make it difficult to find the heartbeat. Once you hear the heartbeat, continue moving the probe slowly until you find the position where the sound is loudest and clearest. At that point, the measurement will be most accurate and interference-free.
