What is the normal value of umbilical artery 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 standard value of the umbilical artery SD at 30 weeks of pregnancy? How much is the standard value of the umbilical artery at 30 weeks of pregnancy? Let's have a simple understanding and understanding of this issue. I hope the following points will be helpful to everyone!

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 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.

Under normal circumstances, the standard value of umbilical artery SD is less than 3 at 30 weeks of pregnancy. The sd value is the ratio of the fetal umbilical artery systolic pressure to the systolic pressure. Careful observation of the changes in the sd ratio can help us discern the growth and development of the embryo. If the SD ratio exceeds 3, it means that the pressure of the fetal blood circulation system is relatively high, and there is a possibility of intrauterine hypoxia.

It is recommended to conduct regular pregnancy checkups. If the SD value is abnormal, oxygen can be given under the guidance of a doctor to relieve the symptoms. Pregnant women can also choose to sleep on their left side when sleeping. Pay close attention to the baby's fetal movements at ordinary times, and seek medical attention immediately if any abnormalities are found.
