How many cm of amniotic fluid is normal at 24 weeks?

A normal measurement is 2 to 8 centimeters (cm). A finding of less than 2 cm indicates low amniotic fluid at this stage. After 24 weeks of pregnancy, the most common way to measure amniotic fluid is called the AFI, or amniotic fluid index.

How many cm of amniotic fluid is normal at 30 weeks?

From a median of 10.3 cm (range, 8.7-13.7, 5th-95th percentile) at 15 weeks’ gestation, the amniotic fluid index rose progressively to a maximum median of 14.0 cm (range, 4.0-18.6) at 30 weeks. The index then gradually declined to a median of 9.1 cm (range, 4.8-14.2) by 40 weeks’ gestation.

How much amniotic fluid is required for normal delivery?

“There is no specific AFI level for a normal delivery. “ “Usually amniotic fluid index ranges between 5 to 25 cm.”

What is normal AFI at 22weeks?

An AFI between 8-18 is considered normal. Median AFI level is approximately 14 from week 20 to week 35, when the amniotic fluid begins to reduce in preparation for birth. An AFI < 5-6 is considered as oligohydramnios. The exact number can vary by gestational age.

What is the normal amount of amniotic fluid at 27 weeks?

What is the normal amniotic fluid index in centimeters?

The sum of the four quadrants, in millimeters or centimeters, is amniotic fluid index. Usually, the normal value of amniotic fluid index varies from 50 mm to 250 mm (or 5 cm to 25 cm). Normal AFI varies from 80 mm to 180mm.

What does low amniotic fluid mean at 32 weeks?

Low Amniotic Fluid. If the AFI shows the fluid as less than 5 centimetres, the absence of the fluid pocket 2-3 cm in depth, or the fluid volume of less than 500 ml at about 32-36 weeks’ gestation, then oligohydramnios is suspected.

How is amnioinfusion done during pregnancy?

Amnioinfusion is done by introducing saline into the amniotic sac through a catheter placed in the cervix during labor. Low amniotic fluid during pregnancy is a serious condition. If you have any concerns about the amount of fluid around your baby, talk with your health care provider.
