Fetal Heart Monitoring

1. FHR Interpreta- changes in response to oxygen, gestation and stimuli
tion
2. EFM provides more objective data than auscultation
3. Monitoring exter- - auscultation
nal contractions - palpation
- EFM toco
- noninvasive
4. Monitoring inter- - intrauterine pressure catheter
nal contractions - measures exact pressure
- invasive
5. Doppler auscul- US converts sound waves to signal of fetal heart
tation
6. Fetoscope aus- - like stethoscope
cultation - open end pressed on abdomen
- not used much
7. Electronic fetal measures fetal heart rate to uterine contractions
monitoring
8. external EFM - ultrasound transducer
- toco
9. internal EFM - fetal scalp electrode
- intrauterine pressure cath
- risk for infetion (2 cm dilation or broke water)
10. Mom setup toco measures by pressure
11. Baby setup US waves

12. Placing monitor toco disc on top of uterus to monitor contractions
on mom
13. Placing monitor - palpate baby head & back
on baby - locate PMI between scapulas
- place sensor
14. Evaluating fetal - baseline rate
heart rate - baseline variability
- accelerations
- decelerations
- changes/trends
15. Normal fetal HR 110-160 bpm
16. when to measure Measure between U/Cs for at least 2 min. period during 10 minute segment
baseline HR
17. fetal tachycardia >160 bpm for >10 minutes
18. fetal bradycardia <110 bpm for >10 minutes
19. Absent variability 0-2 bpm
- undetectable variance
20. minimal variabili- >2 <6 bpm
ty - amplitude range detectable by <5 bpm
21. moderate vari- 6-25 bpm
ability - amplitude range 6-25
22. marked variabili- >25 bpm amplitude
