Study Notes
Nonstress Test
- A nonstress test is an assessment test based on the phenomenon of fetal heart rate response to fetal movement.
- Fetal heart rate slows in response to a uterine contraction.
- A reactive nonstress test is characterized by acceleration of fetal heart rate with each fetal movement.
- In a reactive test, the acceleration of fetal heart rate is at least 15 BPM and lasts for at least 15 seconds.
- A reactive test is considered normal if the acceleration occurs at least twice during the 20-minute test, with each acceleration lasting at least 15 seconds.
- In the given scenario, the nonstress test is considered reactive because the fetal heart rate accelerated 15 BPM with each fetal movement, lasted for 20 seconds, and occurred 3 times during the 20-minute test.
