What is the normal SD value at 30 weeks of pregnancy?

The umbilical artery SD ratio is mainly used to reflect the condition of the fetal embryo and the fetal umbilical cord, and to further observe the growth and development of the embryo. It is necessary to ensure that the SD value is within the normal range. So, how much is the 30-week umbilical artery SD standard worth?

As the pregnancy time of pregnant women increases, the SD ratio also changes. Generally, when a pregnant woman reaches 30 weeks of pregnancy, the standard value of SD is unlikely to exceed 3.0. If the SD value exceeds 3.0, it means that the fetus is facing greater resistance to blood circulation and may be experiencing a lack of oxygen. At this time, you need to lie on your left side or give oxygen under the guidance of a doctor to reduce the fetal intrauterine hypoxia.

Pregnant women are 30 weeks pregnant, which is basically the late stage of pregnancy. In addition to paying attention to the SD value, you also need to pay close attention to the fetal movement. Fetal movement is the most direct way to observe whether the fetus is healthy in the uterus. At 30 weeks of pregnancy, the baby's fetal movements are generally no less than 3-5 times per hour.

However, due to the individual differences of fetuses, the frequency of fetal movements will also vary relatively, but as long as the fetal movements are regular and the changes are not too large, the fetus is normal. However, if the fetal movement of the baby is significantly reduced or increased, it is still necessary to go to the hospital for examination in time. Therefore, pregnant women must attach great importance to every prenatal check-up to ensure their own physical and mental health, and the good growth and development of the fetus.

What should I do if the SD value is high at 30 weeks of pregnancy?

The standard value of SD during pregnancy is between 2.5 and 4. If the SD is higher, it may cause fetal intrauterine hypoxia. For mild SD, you can observe first. If you feel difficulty breathing, you need to give oxygen operation and go to the hospital for a reexamination after one month. Generally speaking, a high SD is a bad omen, and pregnant mothers need to find out the cause and actively cooperate with treatment.

In addition, regular B-ultrasound examinations should be carried out to determine whether the fetus has the umbilical cord around the neck or fetal development is incomplete. Especially in the late pregnancy, if the placenta is severely aged, it will cause insufficient oxygen to the fetus and the mother. Therefore, in the late pregnancy, try to sleep on the left side to ensure the supply of nutrients to the embryo.

Different pregnant women may encounter different problems during pregnancy, so they should carefully observe their own physical abnormalities and do a good job of follow-up work during pregnancy. In addition, appropriate calcium and zinc supplementation in the second half of pregnancy can alleviate the degree of embryonic fragility and ensure the nutrition of the fetus.
