tocometer
Pronunciation: TOKE-oh-mee-ter
A device that measures uterine contractions during labor, typically part of electronic fetal monitoring equipment.
Full Definition
A tocometer (also called tocodynamometer or 'toco') is a pressure-sensitive device used to monitor and record uterine contractions during labor. Placed externally on the maternal abdomen over the fundus, it detects changes in abdominal tension corresponding to uterine contractions. The tocometer provides information about contraction frequency and duration but not intensity, which requires internal monitoring with an intrauterine pressure catheter. This monitoring is essential for assessing labor progress and detecting abnormal contraction patterns that may affect maternal or fetal well-being.
Usage
Usage note: Often shortened to 'toco' in clinical documentation. Ensure proper spelling to avoid confusion with toco- prefix words.
