The fluid is life-sustaining because it cushions the foetus, forbid the umbilical cord from being press, and permit the infant's lung and digestive system to develop right.

When an ultrasound technician performs an AFI check, they divide the uterus into four imaginary quarter-circle. The deep vertical pocket of fluid (excluding umbilical cord loops or foetal limbs) is quantify in each quadrant in centimeter. These four measurements are then append together to calculate the net AFI score.

How Amniotic Fluid Levels Are Categorized

While these value can vary slightly depending on the aesculapian installation and the specific gestational week, the undermentioned guidelines are commonly employ in clinical drill:
