Electronic Fetal MonitoringWhat are the two things measured in Electronic Fetal Monitoring, otherwise known as
Cardiotocography? - ANS-Fetal Heart Rate
Uterine Activity - Contractions
What are the 5 components described in an EFM? - ANS-1. Baseline heart rate
2. Variability
3. +/- Accelerations
4. +/- Decelerations
5. Frequency of contractions
The mean FHR is rounded to nearest ___ bpm during a 10 minute segment - ANS-5
bpm
Normal baseline FHR = - ANS-110-160 bpm
Bradycardia = FHR < _____ bpm for ≥ 10 min - ANS-110 bpm
Tachycardia = FHR > ____ bpm for ≥ 10 min - ANS-160 bpm
Causes of FHR Tachycardia = - ANS-1. Maternal hypotension
2. Umbilical cord prolapse
3. Rapid fetal descent
4. Uterine tachysystole
5. Placental abruption
6. Uterine rupture
7. Myocardial Conduction Defect
Causes of FHR Bradycardia = - ANS-1. Infection (chorioamnionitis)
2. Medications (Terbutaline, cocaine)
3. Fetal anemia
4. Placental abruption
5. Maternal hyperthyroidism
6. Hypoxemia/acidemia
Fluctutations in beat to beat rate; amplitude of peak to trough in beats per minute = -
ANS-Variability
, Variability
Absent =
Minimal =
Moderate =
Marked = - ANS-Absent = Amplitude Range Undetectable
Minimal = Amplitude Range ≤ 5 bpm
Moderate = Amplitude Range 6 - 25 bpm
Marked = Amplitude Range > 25 bpm
Decreased variability or minimal variability is associated with: - ANS-1. Medications
(opioids, MgSO4)
2. Fetal Sleep Cycle
3. Prematurity
4. CNS or cardiac abnormalities
5. *Fetal Hypoxia*
6. *Fetal Acidemia*
________ is associated with severe fetal anemia - ANS-Smooth sine wave - like
undulating pattern
Sinusoidal Pattern
Abrupt increase in FHR with peak of ≥ 15 beats above baseline for at least 15 seconds -
ANS-Acceleration
1. If duration of acceleration is > 2 min it is considered _________
2. If duration of acceleration is > 10 min, it is a __________ - ANS-1. Prolonged
2. Change in baseline
Acceleration is associated with _______ (4) - ANS-1. Fetal movement
2. Demonstrates mature neurocardiac tract
3. Usually indicates fetus is not acidemic
4. *Reassuring of fetal well-being*
Late deceleration is associated with: - ANS-Uteroplacental insufficiency
Early deceleration mirrors uterine contractions and results from ______ which
stimulates the vagus nerve,
