Electro Fetal Monitoring Flashcards

1
Q

Internal fetal monitoring:

A

Fetal scalp electrodes FSE)
Only put in if membranes ruptures and dialated 2-3 cm
Goes into pocket if water and measures exactly how strong moms contractions are

16
Q

Non stress test

A

Baby FHR related to movement
Reactive good
Non reactive bad

17
Q

Term increase FHR of in the baseline

A

15 bpm above the baseline lasting 15 seconds

18
Q

Preterm <32 weeks

A

10 bpm above baseline for 10 seconds

19
Q

What causes fetal response for FHR to have accelerations

A

Fetal movement , contractions, vag exams, breech presentations

20
Q

Accelerations

A

Reassuring sign - indicative of a reactive , heathy fetus

21
Q

Early decals

A

No intervention required but consider doing vag exam
Can indicate head compression
Baby telling us he is on da way

22
Q

Nadir

A

Lowest point of contraction

23
Q

Baseline variability

A

Variation in the base line
Is reflective of neuro maturity

24
Q

Absent base line

A

0-1 bpm
Not good

25
Q

Minimal baseline

A

< or equal to 5 bpm
Biggest indicator that baby is asleep

26
Q

Moderate baseline

A

6-25 bpm
Normal for term baby

27
Q

marked baseline

A

Normal for preterm
Indicated neuro immaturity
Abnormal for term baby

Over 25 bpm

28
Q

Drugs that could contribute to Tachy cardia

A

atropine *and terbutaline *( used a lot for suppression of labor )

And drugs illicit such as cocaine and meth

29
Q

Three responses of fetal that is related to o2 pathway

A

FHR accelerations
Variable decel
Late decel

30
Q

Variables decel

A

Abrupt decrease or abrupt return of FHR
U or v shape
May r may not occur in labor

31
Q

What is considered a severe variable decel

A

FHR below 70 bpm lasting 30-60 seconds
Slow return to base line
Decrease in or absent variability
Intrauterine resuscitation nursing intervention is required

32
Q

Causes of variable decel

A

Umbilical cord compression
Prolapse cord
Nuchal cord
Short cord
Sudden rapid descent of the fetus

33
Q

Late decel

A

Ominous ad potentially disastrous non reassuring sign
Associated with decreased or absent variability

Uterine rescuitation is required

This is a positive that babe is in trouble in a CST .. are we creating late decals when contracting?

34
Q

Late decel

A
35
Q

Positive CST

A

Late de cells are present w/ a minimum of 50 % contractions occur in 10 min

(We monitor for 20 min so it needs to occur in 10 min)

36
Q

Negative CST

A

No late de cels
This is a good thing

37
Q

1 cause of de cel

A

Some kind of placental insufficiency

Post dates, preeclampsia, diabetes, cardiac disease, placental abruption
