Fetal heart monitoring is very important for pregnant women in the third trimester. It is an examination with fetal heart monitoring equipment, which can not only grasp the heartbeat of the fetus, but also judge whether there is hypoxia in the fetus, so as to carry out follow-up examination and treatment in time.
What is fetal heart monitoring? It is a way to monitor fetal heart rate by using various in vivo or in vitro detection instruments and judge whether the fetus is hypoxic according to uterine contraction and fetal movement.
Clinically, we commonly use in vitro detection instruments, which are generally placed on the pregnant mother's stomach for inspection, and are also relatively common instruments.
Fetal heart monitoring is a very effective method to monitor fetal heart, and it is also one of the methods to master fetal health.
When to do fetal heart monitoring? Fetal heart monitoring usually begins after 34 weeks, because the fetus is too small, we can't easily catch the fetal heart, and it is not fixed, and the space is relatively large, so we can move around.
The earliest fetal heart monitoring also started around 32 weeks, because it is meaningless to do it before 32 weeks, and it cannot be used as a basis for diagnosis.
After 32 or 34 weeks, fetal heart monitoring will be added for each prenatal examination, and once a week after 37 weeks. Of course, if it is a high-risk pregnant woman, we will monitor the fetal heart in advance, so that the doctor can determine the location first and let the pregnant mother monitor her fetal heart at home, which will be more reassuring.
At this time, many pregnant mothers will have a question. Is it really meaningful to do fetal heart monitoring so frequently in the third trimester? And it won't affect the fetus? Actually, it really won't. On the contrary, if you don't do it, there will be problems, because we can't find anomalies in time and check them in time. So check it step by step according to the doctor's advice.
Fetal heart monitoring is the most widely used fetal heart monitoring technology in clinic at present, and it is also a simple and painless prenatal examination, which can evaluate the intrauterine situation of the fetus. Especially in the third trimester of pregnancy, continuous monitoring during delivery can find out whether the fetal heart rate is abnormal and deal with it in time.
The time of fetal heart monitoring is generally about 20 minutes, and the monitor is used continuously throughout the process. If there is any abnormality, it can be found in time, and the monitoring time can be extended to see if the fetal heart is really abnormal.
Normal fetal heart rate is 120- 160 times per minute. If the fetal heart accelerates or decelerates more than three times within 20 minutes of fetal heart monitoring, there may be a danger of hypoxia.
Therefore, it is very important to monitor the fetal heart rate during pregnancy, especially in the third trimester, because we should always know the fetal heart rate. Of course, when we don't go to the hospital, we can use a home monitor to monitor, so that we can hear a "strong heartbeat" and monitor the fetal heart rate at any time to ensure the healthy development of the fetus.
