Definition
Meaning
A medical device that continuously tracks and records a fetus's heart rate and the mother's uterine contractions during labor and pregnancy.
A device comprising sensors (transducers) placed on the mother's abdomen or a scalp electrode on the fetus, connected to a display unit. It is used in obstetric care to assess fetal wellbeing, detect signs of distress, and inform clinical decisions during labor and high-risk pregnancies.
Linguistics
Semantic Notes
Often shortened to 'fetal monitor' or 'EFM' in clinical notes. The term explicitly denotes a continuous monitoring device, distinguishing it from intermittent methods like a Pinard stethoscope or handheld Doppler. The adjective 'electronic' is sometimes omitted in professional contexts where the monitoring type is clear.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'электронный плодовый монитор'. The standard Russian medical term is 'кардиотокограф' (for the device) or the descriptive phrase 'аппарат для мониторинга сердцебиения плода'. 'Fetal' is медицинский термин 'плодный', not бытовой 'фетальный'.
Common Mistakes
- Misspelling: 'electonic fetal monitor'. Incorrect plural: 'electronic fetal monitors' (correct). Confusing it with a general 'heart rate monitor'.

FAQ
Frequently Asked Questions
No, it is non-invasive when used externally. Two belts with sensors are placed around the mother's abdomen, which may feel slightly restrictive but not painful.
Routinely during hospital labour, for high-risk pregnancies, induced labours, or if concerns arise about the fetus's wellbeing.
External monitors use belts on the abdomen. Internal monitors involve a tiny electrode placed on the fetus's scalp through the cervix, providing a more precise heart rate signal, but require ruptured membranes.
In many settings, yes. Patients can discuss alternatives like intermittent monitoring with a midwife or doctor, based on their individual pregnancy risk assessment.
