Abbreviation: BPP
A noninvasive evaluation of fetal wellbeing. It consists of four parameters measured via ultrasound (fetal breathing, movement, tone, and amniotic fluid volume) and a nonstress test, which is optional if all ultrasound parameters are normal. Each parameter receives a score of either 0 (abnormal) or 2 (normal) points. The maximum score is 10. A score ≤ 4 indicates potential fetal compromise, which is often taken as an indication for delivery.
