How much is fetal heart rate normal at 37 weeks of pregnancy?
summary
With the development of pregnancy, various organs of the fetus are gradually growing. In the middle of pregnancy, the heart beat of the fetus can be monitored. At this time, doctors can judge whether the fetus is healthy, whether there is hypoxia or abnormality, and how normal is the fetal heart rate at 37 weeks of pregnancy? Now let me tell you something.
How much is fetal heart rate normal at 37 weeks of pregnancy?
Normal pregnancy from the 37th week of pregnancy to do a weekly fetal heart rate monitoring, if there are complications or complications, can be done from the 28th to 30th week of pregnancy. The normal fetal heart rate is 120-160 beats / min, and it is regular and regular, just like the sound of a clock. Of course, if the child exercises in the stomach, it may speed up 10-20 times / min. If it is found that the fetal heartbeat is not in this range during monitoring, it can be measured again in 15 minutes.
If the fetal heart rate is less than 120 / min or more than 160 points for more than 10 minutes, it indicates that the fetal heart rate is abnormal, indicating that the child may be in hypoxia and need to see a doctor immediately. If it is accompanied by irregular heart rate, the situation is even more serious, and expectant mothers should not slack off.
Most cases of abnormal fetal heart rate is on behalf of fetal hypoxia in the uterus. The more serious the degree of abnormal fetal heart rate is, the more severe the fetal hypoxia is. However, not all abnormal fetal heart rate is caused by hypoxia. The fetus may have no congenital heart disease, or over 40 weeks of gestation. Abnormal development of fetal nervous system may also lead to abnormal fetal heart rate.
matters needing attention
It's good for expectant mothers to learn to calculate fetal heart rate during pregnancy. By calculating fetal heart rate, it can help to find fetal abnormal problems, and can be treated in time to avoid fetal hypoxia. Finally, I would like to remind you that in the second trimester of pregnancy, due to the immature fetal heart development, fetal heart rate will change to a certain extent. In the later trimester of pregnancy, fetal heart rate will gradually become regular.
