BPP Flashcards
What are 2 Biophysical components?
Nonstress test and Fetal
What is involved in fetal BPP?
Breathing & movements (for 30 min), tone, qualitative amniotic fluid volume
How is BPP a scored?
2 for performance, 0 for no performance
What is the max BPP score in US parameters?
8
What is the first BPP component that becomes abnormal in the face of fetal hypoxia / academia?
Fetal heart rate reactivity and fetal breathing.
What is concurrently recorded by CTG (cardiotocography)?
Fetal heartbeat and uterine contractions
What does a non stress test record?
Fetal heart rate accelerations or deccelerations due to blood oxygen level changes resulting from uterine contractions
In a non stress test, what are normal and abnormal conditions?
Fetal heart rate acceleration is normal whereas deccelerations are abnormal
What is BPP?
Biophysical profile
What does a score 2 non stress test entail?
2 or more fetal heart rate accelerations of at least 15 beats per minute lasting at least 15 seconds and associated w/fetal movement in 40 minutes
What does a 0 score entail with non stress test?
No acceleration / less than 2 acc’s of fetal heart rate in 40 minutes
What does a score 2 entail with fetal breathing movements?
At least 1 30 second duration of fetal breathing in 30 minutes
What does a 0 score entail with fetal breathing movements?
Absence of breathing or for 30 second duration in 30 minutes
What does a Score 2 entail in fetal movements?
3 or more body/limb movements in 30 minutes (rolling trunk, face, hand, swallowing)
What does a Score 0 entail in fetal movements?
2 or less body movements in 30 minutes
What does a Score 2 entail in fetal tone?
1 or more extensions of a fetal extremity w/return to flexion or opening/closing of hand
