C-EFM study guide
C-EFM · Work through your exam, one topic at a time.
The Certified in Electronic Fetal Monitoring (C-EFM) credential is a specialty certification for nurses, nurse-midwives, and other clinicians who interpret fetal heart rate and uterine contraction tracings as part of perinatal care. It signals that the holder can recognize normal and abnormal patterns, connect them to maternal-fetal physiology, and act on them within accepted clinical and professional standards. The C-EFM study guide has 7 sections and about 1,938 words.
01Maternal and Fetal Physiology
Fetal oxygenation depends on three linked steps: maternal oxygen delivery to the placenta, placental transfer, and fetal circulation. The umbilical vein carries the most oxygenated fetal blood to the ductus venosus, then toward the foramen ovale and left heart, so the brain and heart are preferentially oxygenated.

Electronic fetal monitoring uses Doppler ultrasound for heart rate and tocodynamometry or an intrauterine pressure catheter for contractions. External ultrasound detects motion of cardiac structures; it is affected by maternal obesity, fetal position, and movement artifact.
330 words, about 2 min03Fetal Heart Rate Pattern Interpretation
Interpretation uses four features: baseline rate, variability, accelerations, and decelerations. Normal baseline is 110 to 160 beats per minute.
297 words, about 1 min04Uterine Contraction Assessment
Contractions are described by frequency, duration, intensity, and resting tone. Frequency is counted from the start of one contraction to the start of the next, usually over a 10-minute window.
283 words, about 1 min05Antepartum Fetal Assessment and Testing
Antepartum testing estimates fetal well-being before labor. The nonstress test evaluates fetal heart rate accelerations over a set period; reactivity is generally reassuring.
250 words, about 1 min06Intrapartum Management and Interventions
Intrapartum management focuses on supporting fetal oxygenation while labor progresses. Intrauterine resuscitation includes maternal repositioning (often left lateral), intravenous fluids, oxygen per protocol, reducing uterine activity, and considering amnioinfusion for recurrent variable decelerations.
219 words, about 1 min07Professional Practice, Documentation, and Communication
Professional practice requires accurate, timely documentation and clear communication within the care team. Documentation should reflect the fetal heart rate pattern, interventions, maternal status, and response to interventions.
