Physical Exam Form
There are two parts to the BPP, a Non-stress Test (NST) and an ultrasound evaluation.
The NST involves attaching one belt to the mother’s abdomen to measure fetal heart rate, and another belt to measure contractions. Movement, heart rate and “reactivity” of heart rate to movement are measured for 20-30 minutes. If the baby does not move for a time during the test, it does not mean there is a problem; the baby may be asleep. A nurse may use a small “buzzer” to wake the baby for the remainder of the test.
The ultrasound portion of the test is like any other obstetrical ultrasound performed during pregnancy and is performed by a qualified ultrasound technician who is usually overseen by a perinatologist. The ultrasound may take up to an hour, and the technician will watch for a variety of signs that are important in measuring the health of your baby.
