What is the normal fetal heart sound per minute?

summary

Fetal heart rate monitoring is the abbreviation of fetal heart rate, fetal movement and uterine contraction diagram. It is a graph that uses the fetal heart rate electronic monitor to record the fetal heart rate curve and uterine contraction pressure waveform for clinical analysis. It is the main detection method to correctly evaluate the fetal intrauterine condition, Through the curve of monitoring figure formed by the instantaneous changes of fetal heart rate recorded by signal tracing, we can understand the reaction of fetal heart rate during fetal movement and uterine contraction, so as to infer whether there is hypoxia in the fetus. What is the normal fetal heart sound per minute? Let's talk about my views.

What is the normal fetal heart sound per minute?

First: the normal fetal heart sound should be 120-160 times per minute, more than 160 times should be alert to hypoxia, less than 120 times is more dangerous, because if the fetal hypoxia, first the heart rate is faster, then slowly slower, so fetal heart rate monitoring is very important.

Second: after 28 weeks of gestation, you should listen once a day, one minute at a time, so as to monitor the health of the fetus. Listen to fetal heart sound should pay attention to distinguish with the mother's heartbeat and bowel sounds, fetal heart rate is fast, mother's heartbeat is slow.

Third: twins can also be distinguished by fetal heart sounds. The heartbeat of two fetuses is not exactly the same. Two fetal heart sounds were heard in different parts, the difference was more than 10 times per minute, or there was no sound area between the two fetal heart sounds.

matters needing attention

1. Check fetal heart sound before, avoid bad rest, improper diet, excessive fatigue. 2. Before listening to fetal heart sounds, expectant mothers had better urinate first, then lie flat on the bed, and actively cooperate with doctors. 3. After 28 weeks of gestation, fetal heart sounds can be heard by using a common earpiece, which should be listened to once a day for one minute each time, so as to monitor the health status of the fetus.
