The fetal heart rate monitor cannot hear the fetal heartbeat

A fetal heart monitor is an instrument for detecting fetal heart rate. Some expectant mothers may purchase this kind of fetal heart monitor to check whether the baby is healthy. It is convenient to use and can be tested at home. Through this test, the baby's fetal heart rate can be observed. The normal fetal heart rate should be around 120~160. If it is too high or too low, you should be vigilant. If you can't hear the fetal heart rate, it is best to do corresponding examinations.

The fetal heart rate monitor cannot detect the fetal heart rate

1. Go to the hospital for fetal heart monitoring

During the prenatal check-up, the doctor uses Doppler to check the fetal heart rate. Normal fetal heart monitoring takes about 20 minutes. High-risk pregnant women undergo fetal monitoring, which may take more than 1 hour. 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.

2. Monitor your fetal heart rate at home

There are currently three methods for monitoring fetal heart rate and fetal movement at home: stethoscope, fetal heart (heart) monitor, and fetal talk monitor.

1. Stethoscopes are very common and cheap, but they require high technical skills to be used to find the fetal heart rate, and the sound is relatively small, so it is difficult for ordinary people to hear it.

2. Both fetal heart rate monitors and fetal talk monitors use Doppler auscultation technology. Fetal heart rate monitors can be used to listen to the fetal heart rate, and some can display the fetal heart rate through LED or LCD screens;

3. The fetal talker is a smart device that can basically meet the standards for monitoring the fetal heart rate at home. It is used to listen to and record fetal sounds, count heart rates and fetal movements, draw monitoring curves, and allow doctors to listen to the fetal heart rate remotely. It needs to be connected to a mobile phone application and is suitable for pregnant women with Apple and Android phones.

Apply coupling agent, water or cooking oil on the belly. The reason for applying coupling agent is that ultrasound waves are easily dissipated in the air. Its function is to squeeze out the air in the skin pores and make the probe in close contact with the skin. Turn on the fetal heart monitor, place the probe on the belly, and start looking for the fetal heart rate.
