1

normal metal heart rate?

110 -150

2

tachycardia?

>150

3

bradykardia?

less than 110

4

what is normal baseline variability?

5-25

5

too little?

less than 5

6

too much?

more than 25

7

4 features of a CTG assessment

basline metal heart rate (110-150), baseline variability, presence or absence of decelerations, presence of accelerations

8

which decelerations are ok? not ok?

early decelerations are fine . late ones are no, associated with asphyxia

9

what does DR BRAVADO stand for?

determine risk, contractions, baseline rate, variability, accelerations, decelerations, overall impression

10

what is reassuring varaibalilty?

over 5

11

non reassuring?

if its less than 5 for 40-90 minutes

12

abnormal?

less than 5 for more than 90 minutes

13

what are accelerations?

an abrupt increase in baseline heart rate of >15bpm for >15 seconds

14

they are reassuring, however, absence of them is fine

.

15

decelerations?

abrupt decrease in hr of >15 for more than 15 seconds

16

3 kinds of decelerations?

early, variable or late

17

early decelerations?

start when contraction begins and stops when they stop. NOT PATHOLOGICAL

18

variable - usually due to

cord prolapse

19

late?

begin at peak and finish after contraction ends. They are serious,

20

what do you need to do if you see late d?

metal blood sampling and emergency c section

21

overall impression - reassuring, suspicious, pathological

.

22

metal blood sampling. if pH is less than ______, this is abnormal. what action should be taken?

deliver

23

borderline pH?

7.2 - 7.25, repeat in 30 minutes
