If it is severe hypoxia, pregnant women will feel abnormal fetal movement. In case of mild fetal hypoxia, pregnant women generally have no obvious symptoms. It is often found during fetal heart monitoring that if the hypoxia worsens, pregnant women may experience frequent fetal movements. If the hypoxia is severe, fetal movements will decrease and weaken. In addition, in the case of hypoxia in pregnant women, the fetus is also prone to hypoxia. For example, long bathing time, high water temperature, poor air circulation, pregnant women with heart disease, etc. are also prone to hypoxia. Therefore, it is very important to count fetal movements in the third trimester of pregnancy. The number of fetal movements shall be recorded within one hour in the morning, in the middle and in the evening, and shall not be less than 3-5 times per hour. If the number of fetal movements within 12 hours is less than 10 times, the fetus may suffer from hypoxia, and it is necessary to go to the hospital in time.
