Maternity- Fetal Monitoring/testing

Front 1

external toco transducer

Back 1

monitors contractions nd or fetal movement
applied to maternal abd

Front 2

Baseline FHR

Back 2

Measured when the uterus is at rest for 10 minutes and rounded to 5 BPM

Front 3

Variability

Back 3

•The fluctuation in the baseline FHR.
•Variability occurs because there are many factors which exert a push/pull effect on the fetus and speed up & slow down the FHR.
•FHR is normally irregular –we want to evaluate this
•Described in short term & long term variability

Front 4

Variability Can be Decreased

Back 4

Narcotics & sedatives to mom
•Tacycardia
•Prematurity
•Decrease of O2 to fetal CNS
•Abnormalities of CNS
•Fetal Sleep

Front 5

Accelerations

Back 5

Abrupt, temporary increase in FHR
•Peaks at least 15 beats per min. above the baseline and lasts at least 15 seconds.
•They often occur with fetal movement.
•They have no r/t to contractions
•Usually a reassuring sign

Front 6

CVS is recomended for

Back 6

women with high risk of giving birth to an infant with genetic anomilies

Front 7

Non stress test
purpose

Back 7

evaluate the ability of the fetal heart to accelerate

Front 8

Non stress test
reactive

Back 8

at least 2 fetal heart accelerations with or wothout movemement, occuring in a 20 minute period and peaking 15 minutes above baseline and lasting 15 seconds

Front 9

Non stress test
non reactive

Back 9

tracing does not demonstrae the required characteristicsof a reactive tracing within a 40 minute period

Front 10

>AFP associated with

Back 10

-open neura tube defects
-esophogeal obstruction
-abd wall defects
-hydronephrosis
-threatened abortion
-fetal demise
-

Front 11

> AFP in the normal fetus occurs with

Back 11

-blood contaminated amniotic fluid
-underestimation of fetal age
-muti fetal gestation
-incorrect maternal weight(lower)
-maternal insuline dependent diabetes

Front 12

< AFP associated with

Back 12

-chromosomal trisomies
-gestational trophoblastic disease

Front 13

< AFP in the normal fetus

Back 13

-overestimation of gesational age
-incorrect maternal weight(higher)

Front 14

MSAFP screening

Back 14

offered to all women 16-18 weeks preg

Front 15

Ultrasound
Purpose
1 st trimester

Back 15

- presence and location
-multifetal
-gestational age
- fetal viability
-f/u testing needed
-detects fetal abnormality
-

Front 16

Ulrasound
purpose
2nd and 3rd trimester

Back 16

-fetal viability
-fetal anatomy
-progress of fetal growth
-amniotic fluid volume
-location and relation of placenta and umbilical cord
-fetal presentation
-

Front 17

2nd trimester amnio
done to

Back 17

detect genetic abnormalities

Front 18

3rd trimester amnio done to

Back 18

-fetal lung maturuity
-hemolytic reactions
