How to monitor fetal heart rate?

summary

In fact, as long as pregnant women regularly do the necessary prenatal examination, and then carefully monitor their own fetal heart sound and fetal movement. The fetus is very sensitive to the changes of internal and external environment. Once there are adverse factors for its growth and development, the fetus will first appear abnormal in fetal heart rate and fetal movement: fast or slow, strong or weak, or even disappear. As the saying goes, "fetal heart, maternal heart, heart to heart", fetal heart and fetal movement can convey a lot of information to expectant mothers.

How to monitor fetal heart rate?

Starting time: fetal heart was formed at the end of 8 weeks of pregnancy, and B-ultrasound could detect the beating of fetal heart. At the end of the 20th week of pregnancy, fetal heart sounds can be clearly heard from the abdomen of pregnant women with fetal heart stethoscope, and the frequency and strength of fetal heart can be judged, so as to understand the growth and development of the fetus in the uterus.

Normal fetal heart rate: normal fetal heart rate is 120-160 beats / min, regular rhythm, moderate strength, like the clock "tick" sound. Fetal heart rate can be increased by 10-20 beats / min during fetal exercise. If it is higher than 160 times / min or lower than 110 times / min, it is abnormal.

Abnormal fetal heart rate: at first, the fetal heart rate will be accelerated compensably, the fetal heart rate will rise obviously, more than 160 beats / min, but the heart sound will be weakened. If the cause of the disease can not be removed in time, the fetal heart rate will slow down to below 110 / min, and the heart sound will be weaker or even disappear - fetal death.

matters needing attention

The father to be only needs to buy a fetal heart rate stethoscope. Under the guidance of obstetricians, he can easily learn and master the methods of listening to fetal heart rate and counting fetal heart rate. Although the expectant mother can't hear the fetal heart beat, she should cooperate with her husband closely, take the best position to help her husband listen to the fetal heart sound, and make records at the same time. Note that the fetal heart rate can be heard most clearly on the abdominal wall of the pregnant woman near the top of the fetal back. Fetal movement can only be felt by pregnant women. Therefore, pregnant women should regularly place their palms on the most protruding part of their abdomen. If necessary, they should measure the fetal movement once in the morning, in the middle and in the evening. One hour each time, they can feel the number of fetal movements. Multiplying the sum of three fetal movements by 8 is the number of fetal movements in a day and night.
