Most of the frequent fetal movements found during fetal heart monitoring are normal, because the baby can sense the external stimulation, so the fetal heartbeat will also increase a little during fetal heart monitoring, in a few cases it may be caused by intrauterine hypoxia, which needs timely medical treatment. 1, normal situation: during fetal heart monitoring, there is a probe attached to the fetal heart part, the fetus can also hear the sound of regular heartbeat, the stimulation of sound may cause increased fetal movements, generally 2, intrauterine hypoxia: if the number of fetal movements exceeds the normal number within a period of time, frequent fetal movements, or no intermittent agitation, it may also be a manifestation of intrauterine hypoxia, and should be combined with ultrasound to understand the situation of the fetal indicators for judgment. You can first increase the maternal blood oxygen level through oxygen inhalation to improve the fetal growth and development environment and relieve the symptoms of hypoxia to ensure smooth fetal development. If the cause of intrauterine distress cannot be removed, delivery should be ended within a short period of time so that the fetus can be removed from the intrauterine hypoxic environment and treatment can be given after birth. In a normal pregnancy, fetal heart monitoring is done once a week starting from the 34th week of pregnancy. The fetal movement is measured for 1 hour in the morning, midday and evening, and the fetal movement count for 12 hours is obtained by adding up the 3 fetal movement counts and multiplying them by 4. The fetal movement count is 3-5 times per hour, generally 30 times in 12 hours, which is beyond the normal range of frequent fetal movement. The movement, posture, emotion, strong sound, strong light and touching the abdomen of the pregnant woman can cause the change of fetal movement, which should be observed closely.
