Q. My OB ordered one of these because my blood pressure has been creeping up, and she wants to make sure it's not negatively affecting the baby. The nurse said it would take a bit longer than the other (normal) sonograms. What are they looking for and why is it different than a normal sonogram?
A. A BPP (biophysical profile) is an in depth ultrasound that usually looks at five criteria: fetal breathing, body/limb movements, fetal tone, reactive heart rate, amniotic fluid. Each gets a score of 0-2 points. If all 5 criteria is measured the max score is 10. If four are measured the max score is 8. So your BPP might be 9 out of 10 or 6 out of 8 etc. It gives a more specific look at how the baby is doing.
