Here's a mnemonic for biophysical profile: BAT HAM

Heart rate Acceleration
Here's an overview of interpretations from the BPP score.
BPP 8/10 (Normal AFV)
No fetal indication for intervention.
BPP 6/10 (Normal AFV)
Equivocal. Repeat test within 24 hours.
BPP 4/10 (Normal AFV)
Fetal lungs mature (>37 weeks), deliver.
Fetal lungs immature, betamethasone, repeat test within 24 hours.
General rule: If oligohydramnios, consider delivery.
BPP 8/10 (Decreased AFV)
BPP 6/10 (Decreased AFV)
Assess clinical scenario, consider delivery depending on gestational age, risk of fetal, maternal death, etc.
BPP 4/10 (Decreased AFV)
If >32 weeks, deliver.
If <32 weeks, observe.
Deliver regardless of gestational age.
