6. patterns that are NOT associated with contractions
7. baseline FHR >160 bpm
10. patterns that ARE associated with contractions
11. deceleration that occur with <50% of contractions
13. goal for relaxation time between contractions in the first stage of labor (in seconds)
14. visually apparent, smooth, sine wave-like undulating pattern with a cycle of 3-5 per minute that persists for >/= 20 minutes
15. variability that is >25 bpm
16. variability that is undetectable
17. variability that is detectable but </= 5 bpm
19. contraction pattern with >5 contractions in 10 minutes, average over 30 minutes
20. baseline _________ occurs when the rate is different for >10 minutes
22. abrupt increase in FHR above BL, onset to peak <30 sec (after 32 weeks: ≥ 15 bpm above BL lasting ≥ 15 sec and less than 2 min from onset to return to baseline; before 32 weeks: ≥ 10 bpm above BL lasting ≥ 10 sec from onset to return to

1. fluctuations in BL FHR that are irregular in amplitude & frequency; quantitated as the amplitude of peak-to-trough
2. decelerations that occur with >/= 50% of contractions
3. deceleration that decreases >/= 15 bpm from BL, last >/= 2 minutes but <10 minutes
4. deceleration that is gradual, >/= 30 seconds from onset to nadir, nadir of the decel occurs at the same time as the peak of the contraction
5. deceleration that is abrupt, <30 seconds from onset to nadir, decrease in >/= 15 bpm below BL lasting >/= 15 seconds but <2 minutes
8. baseline FHR <110 bpm
9. variability that is 6-25 bpm
12. mean FHR rounded to increments of 5 bpm during a 10 min window, excluding accelerations, decelerations, and periods of marked FHR variability; must be at least 2 minutes of identifiable segments (not necessarily contiguous) in any 10-minute window.
18. deceleration that is gradual, >/= 30 seconds from onset to nadir, delayed in timing with the nadir after the peak of the contraction
21. contraction pattern with </= 5 contraction in 10 minutes, averaged over 30 minutes
