Fetal-heart rate monitering

WHY do we have fetal heart rate monitering?

to watch if the baby is getting o2

What happens between each contraction & how that effects the placenta (which is completely normal).

Each contraction DECREASES blood flow to PLACENTA but goes back to norm quickly

Keeping in mind what happens between the uterus + placenta during contraction, which organ does this affect of the baby?

the baby’s heart

Which method would the nurse use to know where to place the external fetal HR monitor? What are they looking for and why?

Leopold’s manuever; a smooth surface bc that is the upperback

WHAT does the big red mine indicate?

ONE minute

What does one square mean on the sheet?

10 seconds

What is the newborn heart rate?

110-160

What woul dbe the reason for a tachycardic unborn baby?

Infection

What are the four variabilities of a fetal HR based on its strip?

(Ways to describe any change beat by beat)

Absent, Minimal Marked variability, and Moderate

Absent HR means there is ______ _________ _________ _______.

which means the fetal HR strip will look like a ____________

NO change between HR; flat line

minimal variability means there is _______ _______ _________ ________.

SMALL change between HR

Marked variability means there is _________ ___________ _________.

HIGH change between HR

Moderate variability means that this is __________

OKAY

If a baby has an ABSENT or MARKED HR variability, what should you do?

get HELP

If a baby has a minimal HR variability, what should YOU do as the nurse?

Moniter it

When does a minimal variability usually happen to an unborn baby? (two instances…)

When a baby is sleeping or when they are given opioids

What is it called when the unborn baby’s HR JUMPS to 15 bpm, but 15 sec. later JUMPS right back? Is this safe?

Acceleration; YES

What is it called when HR decelerates & on the strip the LOWEST PART of the baby’s HR matches the PEAK of the uterine contraction?

is this safe, what does it indicate, and what should you do IMMEDATELTY?

Early decel; yes; the baby is coming out; check the cervix

What is the name of the deceleration of the baby’s HR where it GRADUALLY decreases EVERY time AFTER a contraction?

*looks like a early decel, but that lowest part of the HR happens AFTER a contraction, so they do NOT MATCH

Late decel

Late decel means what is happening during that contraction + Placenta?

What is the medical terminology for this?

There is NOT ENOUGH BLOOD in the placenta during each contraction

Uteroplacental Insufficiency

What is the name of the deceleration where the Baby’s HR drops suddenly during a contraction?

Variable decel

If a baby HR drops suddenly BUT stays low for 2 min & longer than it becomes….

PROLONGED decel

What causes that SUDDEN drop in variable decels?

When is this a problem?

Whne the umbilical cord is compressed; ONLY if it lasts longer than 2 min

WHY does prolonged HR decels happen?

oxygen is interrupted

V.E.A.L. C.H.O.P. is a nmemonic that means what?

Meaning that Each letter = the other letter in the word…

Variabilty = Cord compression

Early - head compression

Acceleration = OKAY

Late = Placental insuff

what is the best way to CHECK contraction strength

Palpate the uterus BEFORE and AFTER contraction

How many MINUTES pass between each contraction is the……

frequency

How LONG contractions last is called the…..

duration

How strong a contraction is the…..

intensity

The tone of the uterus BETWEN conctractions can be two tones:

sofr;rigid

When a fetal HR decreases what are THREE interventions you can do as a nurse.

reposition. mom, incr fluids, & Admin terbutaline

How do you admin and What is the SD effect to know abt terbutaline?

SUBQ, causes tachycardiac

What is tachysystole? How do you know a women is experiencing it?

increased contraction: More than 5 contractions within 10 min & less than a min between them

What vital sign of the mom would show that there is placental insuff?

Blood pressure (BP)
