Fetal Monitor Strip Rules

Question 1

How to determine baseline

Answer 1

Look at at least a 2 min strip
the average heart rate
exclude accels/decelerations

Question 2

Normal baseline heart rate

Answer 2

110-160

Question 3

Acceleration

Answer 3

15 bmp inc for at lest 15 sec but not longer than 2 min

Question 4

Early decceleration

Answer 4

Mirrors the contraction

Question 5

Late deceleration

Answer 5

Starts after the contraction peak

Question 6

Variable deceleration

Answer 6

Does not correspond to a contraction

15 bpm and at least 15 sec but less than 2 min

Question 7

Absent variability

Answer 7

undetectable

Question 8

Mild variability

Answer 8

<5 bpm

Question 9

Moderate variability

Answer 9

6-25 bpm

Question 10

Marked variability

Answer 10

> 25 bpm

Question 11

How to measure variability

Answer 11

look at amplitude

change from baseline to highest high or lowest low (excluding accelerations and deceleration)

Question 12

Prolonged deceleration

Answer 12

drop of at least 15 bmp lasting 2-10 min

Question 13

Contractions appropriate time gap

Answer 13

5 or less in a 10 min period

averaged over 30 min
