Learn why a Biophysical Profile (BPP) is sometimes used in pregnancy to (BPP ) is a test that is performed in late pregnancy using ultrasound and fetal monitoring. Your pregnancy has gone past your due date or past 40 weeks gestation. This prenatal test assesses whether your baby is getting enough oxygen in the womb. A biophysical profile is a simple, painless test that's performed during You're past your due date and your healthcare practitioner wants to see how your The test starts with an ultrasound to observe your baby's body movements. One of the major parts of the BPP is a detailed ultrasound. During the ultrasound, the technician is looking for movements of your baby's arms.
Physicians often order the biophysical profile to determine if it's time to induce labor. When a biophysical profile is done The BPP is most common in the third trimester.
Biophysical Profile (BPP) | What to Expect
How a biophysical profile is done A BPP monitors the fetal heart rate similar to a nonstress test and is accompanied by a special ultrasound similar to a level 2 ultrasound. But rather than looking at organs and measurements, the test generally evaluates five aspects of life in the uterus: How your baby's chest moves as she makes practice breaths of amniotic fluid. The number of beats per minute of your baby's heart.
Movements observed over a minute period, sometimes longer if baby's napping. The ability to flex and extend an arm or leg, measured by counting quick, jerky movements.
Biophysical Profile (BPP)
Volume of amniotic fluid: The amount of amniotic fluid surrounding your baby. What do BPP test results mean? Your sonographer will give a biophysical profile score of 0 to 2 in each of the above categories.
Also, keep in mind that it's not always clear that the test can improve pregnancy outcomes. How you prepare A biophysical profile typically requires no special preparation. What you can expect A biophysical profile can be done in your health care provider's office or in a hospital. The test might take 30 minutes or so to complete.
A modified biophysical profile takes less time. During the procedure During the nonstress test, you'll lie on an exam table and have a belt placed across your abdomen.
The belt contains a sensor that measures the fetal heart rate. The heart rate is recorded by a machine. If your baby is asleep, you might need to wait until he or she awakens to ensure accurate results. In some cases, your health care provider might try to awaken the baby by projecting a sound over your abdomen. During the ultrasound exam, you'll also lie on an exam table. Your health care provider or an ultrasound technician will apply a small amount of gel to your abdomen.

Then he or she will roll a small device called a transducer over your skin. The transducer will emit pulses of sound waves that will be translated into a pattern of light and dark areas — creating an image of your baby on a monitor. Your health care provider or the ultrasound technician will then evaluate your baby's breathing movements, body movements, muscle tone and amniotic fluid level.
If your baby is asleep, this portion of the test might take a little longer. After the procedure When the biophysical profile is complete, your health care provider will likely discuss the results with you right away. Results Each area that's evaluated during a biophysical profile is given a score of 0 or 2 points, depending on whether specific criteria were met.Nonstress test and biophysical profile mnemonic
A score can be given immediately. Fetal heart rate monitoring. Results of this portion of the test nonstress test are interpreted as reactive or nonreactive.
If your baby's heartbeat accelerates twice or more a certain amount within a minute period, the results are considered reactive and 2 points will be given.
If not enough accelerations occur within a minute period, the results are considered nonreactive and 0 points will be given. Keep in mind that nonreactive results might occur because your baby was asleep during the test.

If your baby displays at least one episode of rhythmic breathing for 30 seconds or more within 30 minutes, 2 points will be given. If your baby's breathing doesn't meet the criteria, 0 points will be given. If your baby moves his or her body or limbs three times or more within 30 minutes, 2 points will be given. If your baby's movements don't meet the criteria, 0 points will be given.
If your baby moves a limb from a bent position to an extended position and quickly back to a bent position, 2 points will be given. If your baby's muscle tone doesn't meet the criteria, 0 points will be given.
The ultrasound technician will look for the largest visible pocket of amniotic fluid. To obtain a score of 2 points, the pocket must be a certain size.
