A fetal biophysical profile (BPP) is a diagnostic procedure that utilizes ultrasound imaging to assess various aspects of fetal well-being during pregnancy. The BPP evaluates critical parameters such as the volume of amniotic fluid, fetal breathing movements, gross body movements, and fetal muscle tone. This assessment is crucial for predicting potential fetal distress, specifically the presence or absence of fetal asphyxia, and for determining the risk of fetal death during the antenatal period. The procedure is typically performed when the mother presents with a full bladder, which enhances the clarity of the ultrasound images. During the BPP, an acoustic coupling gel is applied to the skin of the lower abdomen to facilitate the transmission of ultrasound waves. A transducer is then placed against the skin and moved across the lower abdomen to locate the fetus and assess cardiac activity. The examination may also include observations of placental position. Following the initial assessment, the ultrasound is used to measure amniotic fluid volume, evaluate fetal movements, and assess breathing patterns. Although the BPP can be performed without a non-stress test (NST), it may also include NST, which involves continuous fetal heart rate monitoring for a minimum of 30 minutes. The results of the BPP are quantified into a biophysical score (BPS), which helps healthcare providers determine the risk of fetal complications. The physician is responsible for reviewing the ultrasound images, interpreting the NST results, calculating the BPS, and providing a comprehensive written report of the findings.
