Obstetrics Monitoring
Typical Use
Continuous fetal heart rate and uterine contraction monitoring during labor and antepartum assessment.
Description
An electronic monitoring system that records fetal heart rate patterns and uterine contractions simultaneously to assess fetal well being during labor and in high risk antepartum situations, combining external Doppler or internal fetal electrode inputs with tocodynamometry or intrauterine pressure catheter data. Cardiotocography aids clinicians in identifying fetal distress, guiding interventions such as intrauterine resuscitation, operative delivery, or expedited cesarean section, and is integrated into labor management protocols. Interpretation requires understanding of baseline rate, variability, accelerations, decelerations, and contraction patterns, and must be correlated with clinical context, maternal status, and gestational age to avoid unnecessary interventions while ensuring fetal safety.
