(last reviewed 08/07/2018)
(last reviewed 08/07/2018)
- Amniotic fluid (AFI or MVP)
- Fetal breathing
- Gross body movement
- Fetal tone
Each variable scored 0 or 2 points
BPP used together with NST for clinical decisions
Abnormal score cannot be given for observation time less than 30 min
Normal BPP = 8/8
Abnormal BPP = 4/8 or less
Equivocal result BPP = 6/8
Fetal breathing
- sustained thoracic movement
- diaphragm excursion
- chest expansion
- M-mode of diaphragm can show movement
- scoring: >/= 1 episode of "breathing" >/=30 sec --> 2 points
- scoring: no episode of "breathing" >/=30 sec --> 0 points
Gross body movement
- trunk roll
- spine flexion or extension
- gross limb movement
- scoring: >/= 3 trunk or limb movements --> 2 points
- scoring:<3 trunk or limb movements --> 0 points
Fetal tone
- Active limb movement - flexion - extension - flexion
- Active limb movement - hand opens and closes
- scoring: >/= 1 episode --> 2 points
- scoring: no episode --> 0 points
Amniotic Fluid volume
- Largest AF pocket is found
- vertical and transverse measurements
- scoring: >/= 1 pocket >/= 2 x 2 cm --> 2 points
- scoring: no pocket of fluid at least 2 x 2 cm --> 0 points
NST (informational)
- Non-US based
- Cardiac reactivity
- Fetal movement
- Uterine contractility
- Observation time 20 min
