Many pregnant mothers will prepare some instruments about their babies at home, one of which is the fetal heart rate. This is a product that can be used to monitor the fetal heartbeat, so how to use it correctly and what should be paid attention to? After all, all the instruments about the baby should be very careful, so let's take a look.
How to use fetal heart rate 1 1 correctly. Lie flat when using fetal heart rate.
Mothers who use fetal heart, please find a comfortable, quiet and undisturbed environment to lie flat, with their heads slightly raised and their legs straight and relaxed. Why do you have to lie flat? Because the fetal heart position will be closer to the abdominal wall of pregnant women when lying down, and the distance from the probe is also close, and the fetal heart sound is easier to hear.
2. Apply coupling agent.
Apply a coupling agent to the stomach (if not, you can apply water or cooking oil, the effect will not be so good), because ultrasonic waves are easily lost in the air, and its function is to squeeze out the air in the pores of the skin and make the probe closely contact with the skin. After drawing, start the fetal heart, put the probe on the stomach and find the position of the fetal heart.
3. Find the location of the fetal heart
Finding the position of fetal heart is the most difficult to control in fetal heart monitoring, and it is an important step to determine whether listening to fetal heart is successful or not. The position of the fetal heart will change with the age of the fetus. Generally speaking:
1 and 6 months ago, the fetal heart was often located in the middle or both sides of the midline of the hypoumbilical abdomen.
2, 6-8 months, with the growth of the fetus, the position of the fetal heart will also move up.
Because fetal movement is usually the movement of fetal hands and feet, when the right side feels frequent fetal movement, the fetal heart is generally on the left side; When the left side feels frequent fetal movement, the fetal heart is generally on the right side. Fetal heart sounds are most clearly heard in the abdominal wall of pregnant women near the top of the fetal back.
4. Read the value correctly
If you find the right position of the fetal heart, you can clearly hear the sound of the fetal heartbeat. Generally, every time you listen to 1-2 minutes, calculate the fetal heart rate of 1 minute. The normal range is 120- 160 times per minute. It should be noted that it is a useful signal that the fetal heart probe receives a stable and continuous fetal heart signal, and the displayed value at this time is desirable.
Correct use of fetal heart rate and step 2 1. What is fetal heart rate?
Fetal heart rate is an instrument used to monitor fetal heartbeat and fetal heart rate. It uses the principle of ultrasound, and its physical strength is inherently smaller than ordinary ones. B-ultrasound equipment has an ALARA principle in the international ultrasound medical field, which is to "obtain the required information with the lowest possible sound output". At present, ultrasound diagnosis plays an irreplaceable role in pregnancy care, and has long been regarded as an ideal and reliable painless, non-invasive and non-radiation safety examination and diagnosis method in obstetrics. Using fetal heart rate can help pregnant women find fetal abnormalities and take effective first aid measures. The use of fetal heart rate must be correct, otherwise it will affect the healthy growth of the fetus.
Second, can fetal heart be used every day?
1, fetal heart rate is an electronic instrument mainly used for monitoring fetal heart rate. General obstetrics and gynecology hospitals will provide fetal heart rate monitoring. Home fetal heart rate is a common product in the market at present, which can be used several times a day, depending on the specific frequency of use and the situation of pregnant women.
2. Pregnant women can use the fetal heart rate of 12 weeks. This is because the fetus has no fetal movement, so it is best to use the fetal heart rate once a day.
3. If the fetus has fetal movement in the second trimester, the mother can gradually reduce the frequency of using fetal heart movement. Considering the fetal movement, if the fetal movement is regular, they can exercise with the fetal heart every two or three days. If the fetus is large in the third trimester, pregnant women are particularly prone to umbilical cord around the neck, respiratory distress and intrauterine hypoxia, so it is best to monitor with fetal heart movement every day.
So to sum up, bringing your own fetal heart can not only help you know the condition of the fetus in time, but also reduce the psychological burden of mothers to a great extent. Mother's mood will greatly affect the development of the fetus, so it is very necessary to raise a fetal heart at home. If the pregnant woman's own physical condition is not very good, it is very necessary to raise a fetal heart at home, because some conditions of the mother may greatly affect the healthy development of the fetus, so it is very necessary to monitor the fetal heart in time.
