A contraction stress test (CST) measures the fetus's ability to
tolerate the stress of uterine contractions started (induced) before true labor
Electronic fetal heart monitoring is done during a contraction
stress test to evaluate the fetus's heart rate during contractions. The fetus's
heart rate during contractions helps evaluate the placenta's ability to provide
enough oxygen to the fetus.
A contraction stress test that shows the placenta is not
supplying enough oxygen to the fetus will help the doctor determine the safest
method of delivery.
A contraction stress test is also called an oxytocin challenge
