COMPLETE SOLUTIONS
Acceleration - -Onset to peak <30 seconds
- >15 bpm above baseline by >15 seconds but <2 minutes
-(Before 32 weeks gestation: peak >10 bpm and lasting >10 seconds)

Prolonged Acceleration - >2 minutes but <10 minutes

Early Deceleration - -Gradual decrease and return of FHR associated with a contraction
-Onset to nadir of >30 seconds
-Nadir occurs at the same time as the peak of the contraction

Late Deceleration - -Gradual decrease and return of FHR associated with a contraction
-Onset to nadir of >30 seconds
-Nadir occurs after the peak of the contraction

Prolonged Decleration - -Abrupt decrease with onset to nadir <30 seconds
-The decrease is >15 bpm by >15 seconds but <2 minutes

Recurrent Decelerations - Decelerations occurring with >50% of contractions in any 20 minutes

Intermittent Decelerations - Decelerations occurring with <50% of contractions in any 20
minutes

Sinusoidal Pattern - Visually apparent, smooth, sine wave-like pattern in FHR with cycle
frequency of 3-5/minute that persists for >20 minutes

Tachysystole - More than 5 ctx in a 10 minute segment averaged over a 30 minute period

Narcotic FHR Affects (2) - -Decrease in variability
-Decrease in frequency of acceleration

Stadol FHR Affects (2) - -Transient sinusoidal FHR pattern
-Slight increase in baseline rate

Cocaine FHR Affects (1) - -Decrease in variability

Corticosteroid FHR Affects (1) - -Decrease in variability with betamethasone but not
dexamethasone

Magnesium Sulfate FHR Affects (2) - -Decrease in variability
-Inhibition of increase accelerations as gestational age advances

Terbutaline FHR Affects (1) - Increase in baseline rate
