EFM Terminology

2. Pattern not associated with contractions.
3. Visually apparent abrupt decrease in FHR that may occur with or without contractions.
5. Decelerations occurring with less than 50% of contractions in a 20-minute segment.
7. Baseline FHR greater than 160 bpm.
10. Pattern associated with contractions.
11. Smooth, sine wave-like undulating FHR baseline pattern that persists for at least 20 minutes.
13. Presence of accelerations and moderate variability reliably predict the absence of fetal metabolic ________
16. Mean FHR rounded to increments of 5 bpm during a 10-minute window.
19. Baseline FHR less than 110 bpm.
20. Baseline FHR variability that is detectable but less than or equal to 5 bpm

1. Decelerations that occur with 50% or more of uterine contractions in a 20-minute window.
4. Fluctuations in baseline FHR that are irregular in amplitude and frequency.
6. Baseline FHR variability greater than 25 bpm
8. Abrupt increase in FHR above baseline.
9. Visually apparent decrease in FHR lasting 2 minutes or more but less than 10 minutes
12. Predictable timing deceleration in which the nadir occurs after the peak of the contraction.
14. Category of FHR tracing that is abnormal and predictive of abnormal fetal acid-base status at the time of observation
15. Baseline FHR variability amplitude of 6–25 bpm
17. More than 5 contractions in 10 minutes, averaged over 30 minutes.
18. Lowest point of a deceleration.
