Fetal heart is normal, umbilical blood flow is normal, bad acceleration of fetal monitoring has an effect, and there may be a risk of fetal hypoxia. Fetal heart rate monitoring is an indispensable prenatal examination, which can continuously monitor the dynamic changes of fetal heart rate. When the late pregnancy obstetric examination suggests that the fetal heart is normal, the umbilical cord blood flow is normal, but the fetal monitor acceleration is not good to suspect that there may be fetal hypoxia, follow the doctor’s instructions to give oxygen, change the position, rehydration and other intrauterine resuscitation treatment is still not improved, the need for timely admission to the hospital for observation, and terminate the pregnancy at the appropriate time. Fetal heart is normal, umbilical cord blood flow is normal does not indicate that the fetus has no chronic hypoxia, when the acceleration is not good and after the initial treatment does not improve, need to follow the doctor’s advice to give the contraction stimulation test to understand the intrauterine reserve of the fetus, when there is an abnormal positive result, need to terminate the pregnancy in a timely manner.
