Which parameters are assessed during a Biophysical Profile (BPP)?

A Biophysical Profile (BPP) is an important prenatal assessment that evaluates the well-being of a fetus, typically conducted during the third trimester of pregnancy. The parameters typically assessed in a BPP include fetal breathing movements, fetal movement, fetal tone, and the amount of amniotic fluid present.

Breathing refers to the observation of at least one episode of fetal breathing movements lasting 30 seconds or more during the assessment period. Movement assesses whether the fetus exhibits general movements, indicating neurological function and normal development. Tone focuses on the presence of flexed limbs and the overall muscle tone of the fetus, which can give information about its neurological health. The amount of amniotic fluid is evaluated through a measurement known as the amniotic fluid index, which provides insight into the fetus's environment and well-being.

The combination of these assessments provides a comprehensive overview of fetal health, allowing healthcare providers to make informed decisions regarding monitoring or intervening if necessary. Thus, assessing breathing, movement, tone, and fluid provides vital information that contributes to understanding fetal well-being.
