Fetal Monitoring Flashcards
Accelerations
Fetal movement=fetus moves then HR increase
2 Acceleration within a 20 minute period
Late deceleration
Poor placental perfusion
=decrease blood flow
Variable declarations
Umbilical cord compressed
early deceleration
The natural response when the uterine contraction
Decelerations
Fatal head compressed
Blood flow decreases
Leopold maneuvers
What we can determine?
Presenting part
Fetal lie
Location of the fetus back
What is the heartbeat?
a) Minimal variability
b) Moderate variability
c) Marked variability
a) 5bp/m
b) 6-25bp/m
c) greater than 25bp/m
Nursing intervention
Non reassuring case
Change position
Increase IV Fluids
Oxygen by nonrebreather mask
Why Monitor?
Identify signs of fetal hypoxia
Assessment of uterine activity
Which can affect oxygen delivery to the fetus
External monitoring
Where to place
a) ultrasound and b) taco
a) fetal back
b) uterine fundus
External monitoring
a) Advantage
b) Disadvantage
a) Noninvasive
b) Doesn’t provide contraction strength
Limits mobility
Non-reassuring are?
Increase or decrease in baseline
Absent or minimal/variability
Less than 2 accelerations in a 20 min period
Accelerations measurement
15 beats above the baseline
lasting for at least 15 seconds
2 accelerations in a 20 min period
Contraction
Frequency – How do we measure?
Start of one contraction to start of the next
Contraction
Duration – How do we measure?
Start of one contraction to the end of that contraction
