Week 01 Flashcards
Intron to Mother Baby and Electronic Fetal Monitoring (EFM) (65 cards)
non-stress test (NST)
assess fetal well-being, uses external monitoring, noninvasive, 20 minutes
ultrasound
external monitor to monitor contractions
tocodynamometer (TOCO)
external monitor to monitor contractions
fetal scalp electrode
internal monitor to monitor fetal heart rate
intrauterine pressure catheter
internal monitor to monitor contractions
oxygenation during contractions
blood flow through uterus decreases > blood flow from uterus to placenta decreases > decreased oxygen to fetus > healthy fetus should be able to tolerate
baseline FHR
average heart rate over 10 minutes
variability FHR
beat to beat change in the FHR
absent variability
0 BPM change
minimal variability
1-5 BPM change
moderate variability
6-25 bpm change
marked variability
25+ BPM change
what is the desired variability
moderate variability
deceleration
short-term, but clear decrease in FHR
what are the 3 types of deceleration
early, variable, late
early deceleration
lines up with contraction
variable deceleration
V shaped, after contraction
late deceleration
right after contraction
category 1
- FHR 110-160
- moderate variability
- no deceleration
- accelerations are present
category 2
- tachycardia or bradycardia with good variability
- minimal or absent variability without deceleration
- early deceleration
- acceleration can be absent or present
category 3
- tachycardia or bradycardia
- no variability
- recent deceleration
- sinusoidal
uterine resuscitation
- IV fluid bolus (500-1000 mL LR)
- maternal position changes
- left lateral tilt
- oxygen at 10 L via non-rebreather
- turn off pitocin
cervical change effacement
0-100
cervical change dilation
1-10
