Q

Why knowing the resting tone important

A

Allows the fetus to recover and have oxygen exchanged occur

17
Q

Bradycardia

A

FHR <110 BPM greater than 10 mins

18
Q

Bradycardia causes

A

Late fetal hypoxemia, Drug induced, prolonged cord compression, fetal congenital heart block, maternal hypothermia, prolonged maternal hypogylcemia,

19
Q

Absent Variability

A

undetectable FHR

20
Q

Minimal Variability

A

</= 5bpm

21
Q

Moderate Variability

A

6-25 bpm

22
Q

Marked Variability

A

> /= 25

23
Q

Periodic

A

Occurs w/ cxt

24
Q

Episodic

A

non associated with cxt

25
Q

Etiology of Accelerations

A

Fetal movement​

Vaginal exam​

Internal Scalp electrode application​

Fetal Scalp Stimulation​

Fetal reaction to external sounds or stimulations​

Breech presentation​

Uterine contractions​

Partial cord compression of the umbilical VEIN resulting in decreased fetal venous return​

26
Q

Early Decelerations Cause

A

Head Compression -> reflex vagal response c resultant slowing of FHR during the UC. ​

27
Q

What does Early Decelerations look like

A

A mirror reflection of the cxt

28
Q

What does Variable Deceleration look like

A

V or W

29
Q

Variable Deceleration causes

A

Cord Compression​

Can be periodic or Non-periodic (Episodic)​

Short cord​

Knot in cord​

Prolapsed cord = emergency situation

30
Q

Late Deceleration causes

A

Uteroplacental insufficiency​

Maternal Hypotension/hypertension​

Diabetes​

Decrease in fetal oxygen reserves​

​Cause by impairment in oxygen exchange

31
Q

What is the BIG 5 Interventions

A

Stop the Oxytocin/Pitocin​

Turn the patient or reposition the patient​

02 per facemask – 8 to 10 L/min​

IV fluids or Fluid bolus​

Call Health Care Provider​

32
Q

VEAL

A

Variable Deceleration​

Early Deceleration​

Acceleration

Late Deceleration

33
Q

CHOP

A

Cord Compression
Head Compression
Oxygen/Movement
Placental/Uterine insufficiency

34
Q

MINE

A

Move the patient​

Investigate if delivery is coming​

Nothing – this is a good sign​

Everything/Know the Big 5​

35
Q

Category 1

A

Baseline: 110-160 bpm​
Moderate variability​
No Late or Variable decels,​
+/- Early decels,​
+/- Accels

36
Q

Category II

A

Everything not categorized as Category I or III​
​Examples : ​
Tachy, Brady with normal variability​
Absent, minimal, or​ marked variability​
Lates + mod variability, ​unusual variables​

37
Q

Category III What is it

A

Absent variability, plus either…..​
Recurrent late/variable decels,​ Bradycardia​
Sinusoidal pattern​

38
Q

Category III

A

Abnormal Fetal Acid and base status

39
Q

Aminofusion

A

Infusion of room-temperature isotonic (normal saline, lactated Ringer’s solution) fluid into the uterine cavity to relieve intermittent umbilical cord compression resulting in in variable decelerations and transient fetal hypoxemia. ​

40
Q

Purposes of Aminofusion

A

Treatment of Variable Decels ​
Low amniotic fluid
