If the s/d value is high, it is necessary to induce labor if the fetus is found to have abnormalities; if the fetus is not found to have abnormalities, it is not necessary to induce labor, and oxygen can be given. High s/d value is caused by high blood flow in the umbilical cord, which leads to intrauterine oxygen deprivation of the fetus. When an abnormally high s/d value is found, it is necessary to carry out anomalous examination, as well as to test the fetal heartbeat, fetal movement, and the maturity of the placenta. Elevated s/d values can lead to intrauterine hypoxia and developmental delay. If there are no fetal malformations, the patient should go to the hospital in time and be treated with oxygen. The pregnant woman should pay attention to reasonable rest, avoid over-exertion, and pay close attention to the fetal heart and fetal movement in the uterus. If the fetus is found to have malformations, it is necessary to terminate the pregnancy and induce labor.
