Three Tier System:

Describe Category 2 Variability:

-Minimal (< or = to 5bpm but detectable)
-Absent (undetectable) *But NOT accompanied by recurrent decelerations
-Marked (>25bpm)

32

Three Tier System:

Describe Category 2 Accelerations/Decelerations:

Accelerations
-Absence of acceleration with scalp stimulation

Decelerations:
-Late/Variable/recurrent/Prolonged

33

Bradycardia <110bpm with preserved variability

Category?

Category 2

34

Absence of acceleration with scalp stimulation

Category?

Category 2

35

Tachycardia > 160bpm

Category?

Category 2

36

Describe Category 1:

"Strongly predictive of normal fetal acid-base status"

37

"Strongly predictive of normal fetal acid-base status" Describes what category?

Category 1

38

Describe Category 2:

"Indeterminate.... [they] require evaluation and continued surveillance and reevaluation, taking into account the entire associated clinical circumstances"

39

"Indeterminate.... [they] require evaluation and continued surveillance and reevaluation, taking into account the entire associated clinical circumstances" describes what category?

category 2

40

Describe category 3:

"Predictive of abnormal fetal acid-base status"

41

"Predictive of abnormal fetal acid-base status" describes category?

Category 3

42

Moderate variability predicts pH

> 7.15
-Negative predictive value 98%

43

Minimal/absent variability AND decels are associated with a pH

<7.15
- though predictive value still poor (23%)

44

Increases with depth of recurrent decelerations increases the

likelihood of acidemia
*especially late and w/minimal or absent variability

45

pH > 7.15

moderate variability

46

pH < 7.15

absent or minimal variability and decels

47

Name, in order the evolving fetal compromise process:

1. Recurrent variable/late decels
2. Progressively deeper decelerations
3. Reflexive fetal tachycardia (+/-)
4. Progressive reduction in variability moderate to minimal to absent
5. Terminal Bradycardia

48

Reverse order of fetal compromise process (5 steps):

5. terminal bradycardia
4. progressive reduction in variability moderate to minimal to absent
3. reflexive fetal tachycardia (+/-)
2. Progressively deeper decelerations
1. Recurrent variable/ late decelerations
