What is a Contraction Stress Test?

• Done when biophysical profile is 4 or 6.

• Tests the ability of the fetus to tolerate transitory decreases in intervillous blood flow that occurs with uterine contraction.

• Detects the presence or absence of late decelerations.

• Late decelerations are gradual decreases in fetal heart rate below the baseline with onset to nadir ≥ 30 seconds.

• The deceleration onset is delayed in relation to contractions.

• Three contractions in 10 minutes must be present.

Negative Contraction Stress Test:

• No late decelerations with 3 uterine contractions in 10 minutes.

• Reassuring.

• Repeat weekly.

Positive Contraction Stress Test:

• Late decelerations seen with 3 uterine contractions in 10 minutes.

• Non-reassuring.

• Promptly deliver.
