Since pregnancy, expectant mothers have become sensitive to everything about their babies, especially the health of their babies. Although the fetus has been living in the womb, but the expectant mother can not see him, it is inevitable that there will be inexplicable worry. Fetal heart monitoring can detect the health of the fetus, so that mothers-to-be can understand the development of the fetus in the first time, to eliminate the anxiety of mothers-to-be. How often can you measure fetal heart? What are the factors contributing to abnormal fetal heart rate? Does the expectant mother know? Mothers can also monitor their fetal heart by using their own family plans. Let’s look at the knowledge of fetal heart monitoring.

How often can you measure fetal heart?

It can be detected at least 42 days after menopause.

For normal intrauterine pregnancy, the general B-ultrasound examination in menopause 42 days, you can clearly see the embryo bud in the uterus, and fetal heart tube pulsation. Some women with irregular menstrual cycles, late ovulation, and late implantation of fertilized eggs have fetal buds in their uterus, and the fetal heart tube pulsation time will be relatively late, but not more than 49 days after menopause, not later than 56 days at the latest. If more than 56 days, no intrauterine embryo is found, fetal heart tube pulsation should be diagnosed as embryo. Stop breeding.

How much pregnant can you listen to fetal heart?

It can be heard in the first 6-7 weeks.

Usually 6-7 weeks of pregnancy, in the B-ultrasound examination, the mother-to-be can see the baby’s fetal heart beat from the B-ultrasound fluorescent screen, but at this time the fetal heart beat is very weak, is not suitable for home fetal heart monitor.

If a prospective mother wants to listen to her fetal heart at home with a fetal heart meter, she usually needs to be 16 weeks pregnant, but there are also some that can be measured at less than 16 weeks. Others need about 20 weeks to monitor the fetal heart rate with a home fetal heart meter, depending on the situation, such as the improper method of the pregnant mother, or the abdomen of the prospective mother. Fat is thick and so on, will affect the monitoring of fetal heart.

What are the important functions of fetal heart monitoring?

Fetal heart rate monitoring is the abbreviation of fetal heart rate, fetal heart rate and uterine contraction pressure waveform recorded by electronic fetal heart rate monitor for clinical analysis of the graphics, is the correct assessment of fetal conditions in the uterus of the main means of detection. It plays an important role in early detection of abnormal fetal heart rate and timely treatment and reduction of perinatal mortality.

Fetal heart monitoring is mainly based on two lines:

The above shows that the fetal heart rate fluctuates between 120 and 160 under normal conditions. In general, the baseline heart rate line shows a wavy line. When the fetal movement occurs, the heart rate rises, and there is an upward curve. After the fetal movement, the fetal heart rate slowly drops. The fetal movement count > 30 times per 12 hours is normal, and < 10 times per 12 hours indicates the fetus. The child is anoxic.

The next one indicates that the intrauterine pressure will increase as long as the child shrinks, and then it will maintain about 20mmHg.

In addition to the fetal heart rate monitoring carried out at each birth check-up, usually at home can also have a home fetal heart rate meter to detect fetal heart rate, expectant mothers can always detect the growth and development of the baby.

What are the factors contributing to abnormal fetal heart rate?

1, emotion: if a mother is mentally excited, angry or sleepless, it will affect fetal heart rate monitoring. Therefore, expectant mothers should maintain a good sleep and a good state of mind, try to relax their emotions, to avoid great joys and sorrows.

2, diet: expectant mothers drink strong tea coffee or too hungry can make fetal heart abnormalities. Therefore, expectant mothers should eat a reasonable diet, try to eat lighter, less tea and coffee, eat less pepper and other stimulating food.

3. Hyperthyroidism: If the mother-to-be suffers from hyperthyroidism, her heart rate is fast, which is also the cause of affecting fetal heart rate monitoring.

4. Drugs: If the expectant mother takes Shuchuanning, Atropine drugs, may also cause fetal heart rate abnormalities, fetal heart rate acceleration.

5. Fever: Feeling fast heartbeat is normal when you have a fever. This is a metabolism of the body. Body temperature is directly proportional to the fetal heart rate. The higher the fever degree of the expectant mother, the faster the fetal heart rate.

For the health of the fetus, expectant mothers please control their emotions, reasonable diet, pay attention to rest, do not use drugs casually, take good care of themselves, is to take good care of the baby. Mother-to-be also do not give themselves too much pressure, oh, baby and mother will stand in the United Front, work together.
