Fetal Non Stress Test
A contraction stress test measures the fetal heart rate after the mother’s uterus is stimulated to contract. This test is done to make sure the fetus can handle contractions during labor and get the oxygen needed from the placenta
During the test, your doctor will place two straps over your abdomen—one to measure contractions, the other to measure fetal heart tones. Your doctor will administer Pitocin (artificial oxytocin) to induce contractions. Alternately, you may stimulate your nipples by rubbing them, which can also bring on contractions
An NST takes about 15-45 minutes. You don’t need to do anything special to prepare for it. A device that monitors the baby is attached by a belt to your abdomen. Another monitoring device is attached to your abdomen to see if you are having any uterine contractions.
