Umbilical blood flow is a test that pregnant women need to undergo during pregnancy, usually around the 30th week of pregnancy. However, after undergoing umbilical blood flow examination, pregnant women are unsure of the specific indicators to be examined and want to clarify what the examination is for. What indicators should pregnant women check for umbilical blood flow?
Pregnant women's examination of umbilical blood flow mainly focuses on indicators such as the ratio of the lowest diastolic blood flow velocity to the highest systolic blood flow velocity of the umbilical artery, pulsatility index, and resistance index to reflect the condition of blood flow. It mainly checks the blood supply and oxygen supply to the fetus, and can also detect whether the fetus has chromosomal abnormalities, hereditary blood diseases, etc. For pregnant women, examination is crucial.
Umbilical blood flow examination can be completed in the B-ultrasound room or in the fetal heart monitoring room, and the examination is not difficult. Its normal value varies with the number of weeks of pregnancy and is not always fixed. It doesn't matter if the pregnant woman can't understand whether the values are normal after undergoing umbilical blood flow examination. The doctor will analyze the examination data.
It should be reminded that umbilical cord blood flow examination is only one of the many examination items for pregnant women. It also needs to be combined with fetal heart monitoring, fetal head circumference, body length, and other factors to make judgments. In the late stage of pregnancy, it is necessary to analyze whether the fetus has umbilical cord around the neck, and other aspects. It is not simply a matter of data to make a conclusion, so do not be too nervous and relax.
