Normal amniotic fluid values ​​in late pregnancy

The fetus lives in the amniotic fluid in the mother's body, and the amniotic fluid is very important to the baby. The baby will grow and breathe in the amniotic fluid to maintain basic physiological needs. Normal amniotic fluid is about 8 to 18 centimeters. It should not be too much or too little. In the late pregnancy, you should check whether the amniotic fluid is normal in time. Let’s take a look at this aspect.

Normal amniotic fluid values ​​in late pregnancy

1. Amniotic fluid index in late pregnancy

The normal value is 8-18 cm. The normal value of amniotic fluid of 3-8CM usually refers to the maximum depth of amniotic fluid. If the amniotic fluid is less than 3CM, it means there is too little amniotic fluid, and if it is greater than 8CM, it means there is too much amniotic fluid. Too much or too little amniotic fluid is harmful to the fetus.

2. The significance of amniotic fluid

It refers to the fluid in the amniotic cavity of the uterus during pregnancy. Throughout the pregnancy process, it is an important component that is indispensable for maintaining fetal life.

The source of amniotic fluid varies at different stages of fetal development. During the first trimester of pregnancy, amniotic fluid mainly comes from the plasma components of the embryo; afterwards, as the embryo's organs begin to mature and develop, other sources of amniotic fluid, such as the fetal urine, respiratory system, gastrointestinal tract, umbilical cord, placental surface, etc., also become sources of amniotic fluid.

The amniotic fluid index is calculated by adding the depths of amniotic fluid in four areas: upper, lower, left and right, with the pregnant woman's navel as the center during B-ultrasound. The normal value of the amniotic fluid index in late pregnancy is 8-18 cm. The normal value of amniotic fluid of 3-8cm refers to the maximum depth of amniotic fluid. Ultrasound examination indicates the vertical depth of the largest amniotic fluid pool. Less than 2 cm indicates too little amniotic fluid, and greater than 8 cm indicates too much amniotic fluid.

The above is the editor’s summary of the information on what is considered normal amniotic fluid index in the late pregnancy. From the above information, you can know the importance of amniotic fluid to the fetus and what it will look like if there is too much amniotic fluid. There are also some data for reference. Based on the above data, pregnant mothers can use it as a reference to see the condition of the fetus and their own physical condition. I hope my compilation will be helpful to you.
