The criteria for passing the fetal heart rate monitoring is that the fetal heart rate has a stable baseline of 120-160 beats per minute within 20 minutes, and the fetal heart rate accelerates at least twice during activity, at least 15 beats per minute faster than the fetal heart rate baseline, each time lasting at least 15 seconds, and there is no deceleration of the fetal heart rate or occasional variable deceleration, but the duration is shorter than 30 seconds, then the fetal heart rate monitoring result is normal This also means that the fetus is in good condition. If the fetal heart rate fails occasionally, it can often be improved through adequate rest, balanced nutrition and psychological regulation. If the fetal heartbeat fails several times, it may indicate intrauterine distress. To avoid affecting the normal growth and development of the fetus in the womb, appropriate treatment should be given according to the doctor’s requirements. In addition, pregnant women should eat a full meal before the fetal heart monitoring to avoid starvation state that leads to fetal heart monitoring failure. In the process of fetal heart monitoring, you can mainly lie on your left side. If you do not feel any obvious fetal movement during fetal heart monitoring, it is possible that the fetus is in a sleeping state, so the pregnant woman can put on relaxing music or slight swaying to wake up the baby, which is also conducive to the successful passing of fetal heart monitoring.
