What is a normal value for a single vertical pocket of amniotic fluid indicated in an AFI?

In assessing amniotic fluid volume using the single vertical pocket method, a normal value is greater than 2 cm. This measurement indicates an adequate amount of amniotic fluid, which is essential for fetal development, cushioning, and mobility within the uterus.

A single pocket of amniotic fluid measuring more than 2 cm suggests that the fetus has sufficient fluid surrounding it, which supports normal physiological functions such as lung development and musculoskeletal growth. If the pocket measures less than this threshold, it could raise concerns about oligohydramnios, which may warrant further evaluation or intervention.

Values such as at least 5 cm or at least 10 cm pertain to different methods of measuring amniotic fluid levels, such as the Amniotic Fluid Index (AFI), where those higher thresholds are often indicative of normal polyhydramnios rather than a single pocket assessment.
