fetal monitoring Flashcards
(33 cards)
- fetal well-being
- signs of compromise
- response of FHR & uterine contractions (UC)
electronic fetal monitoring
intermittent monitoring examples
fetoscope, doppler, ultrasound transducer
- only low-risk omen on no pitocin/epidural
- NST completed beforehand
- intermittent auscultation every 15-30min during active labor, every 5-15min while pushing
guidelines for intermittent fetal monitoring
what measures uterine contractions/activity?
TOCO, palpation
machine to produce continuous tracing FHR, most common practice
continuous EFM
external measuring of FHR
ultrasound transducer
external measuring FHR
fetal scalp electrode (FSE)
external monitoring uterine activity
TOCO
internal monitoring uterine activity
intrauterine pressure catheter (IUPC)
- if receiving pitocin/epidural
- review q30min during 1st stage
- q15min while pushing
continuous EFM guidelines
measured from time start to time end of contraction
duration
beginning of one contraction to beginning of another contraction
frequency
how much FHR changes from second to second
variability
flatline
absent variability
0-5 beats change
minimal variability
6-25 beats change
moderate variability
> 25 beats change
marked variability
15beats above baseline lasting for at least 15sec
acceleration
these signify cord compression
variable decelerations
these signify head compression
early decelerations
these signify uteroplacental insufficiency
late decelerations
interventions for late decelerations
- IV bolus
- discontinue oxytocin
- change maternal position
- notify MD after interventions
- prepare for c-section
only occur with contractions
periodic changes
not always associated with contractions, but sometimes do
episodic changes
