Fetal movement and fetal heart rate monitoring can be used during pregnancy to determine whether the fetus is suffering from hypoxia. 1. Fetal movement: during pregnancy, especially in the late stage of pregnancy, fetal movement can reflect the condition of the fetus in the uterus, if there is a sudden increase or decrease in fetal movement, it should be considered that the fetus in the uterus is suffering from hypoxia. 2. Examination: Fetal heart rate monitoring is to monitor the heart rate of the fetus through electronic monitoring instruments to determine the health of the fetus, this examination can also clearly diagnose whether the fetus has hypoxia. Fetal hypoxia will affect the growth and development of the fetus, or even endanger the life of the fetus, once suspected fetal hypoxia, you need to go to the hospital for examination.
