A biophysical profile (BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system,[1] with the score being termed Manning's score.[2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications. Show
The "modified biophysical profile" consists of the NST and amniotic fluid index only. Procedure[edit]The BPP has 5 components: 4 ultrasound (US) assessments and an NST. The NST evaluates fetal heart rate and response to fetal movement. The five discrete biophysical variables:
Use of vibroacoustic stimulation to accelerate evaluation has been described.[4] Interpretation[edit]Each assessment is graded either 0 or 2 points, and then added up to yield a number between 0 and 10. A BPP of 8 or 10 is generally considered reassuring. A BPP normally is not performed before the second half of a pregnancy, since fetal movements do not occur in the first half[citation needed]. The presence of these biophysical variables implies absence of significant central nervous system hypoxemia/acidemia at the time of testing. By comparison, a compromised fetus typically exhibits loss of accelerations of the fetal heart rate (FHR), decreased body movement and breathing, hypotonia, and, less acutely, decreased amniotic fluid volume. Recommended management based on the biophysical profile[5]

How many parameters should a biophysical profile have?The fetal biophysical profile (BPP) is a noninvasive, easily learned and performed antepartum test for evaluating fetal well-being. Ultrasound is used to assess four discrete biophysical parameters: fetal movement, fetal tone, fetal breathing, and amniotic fluid volume.
What are the 5 parameters of the biophysical profile?During the biophysical profile, your provider is looking at 5 main areas to check your baby's health: body movements, muscle tone, breathing movements, amniotic fluid, and heartbeat. Each of these 5 areas is given a score of either 0 (abnormal) or 2 (normal).
What items are assessed in a biophysical profile?A biophysical profile (BPP) includes ultrasound monitoring of fetal movements, fetal tone and fetal breathing, ultrasound assessment of liquor volume with or without assessment of the fetal heart rate.
How many parameters are to be considered in the biophysical profile and what is the highest potential score for each parameter?The BPP tests four parameters over a 30-minute observation period. The fetus receives a score of zero or two points for each parameter, and the sum is the BPP score. A score of 6/8 or 8/8 is normal. Most fetuses that score ≤ 6/8 need additional monitoring.
