Which type of fetal monitoring involves placing a device on the mother's abdomen?

External monitoring involves placing a device on the mother's abdomen to assess the fetal heart rate and uterine contractions during labor. This non-invasive method utilizes an ultrasound transducer that is placed on the abdomen to collect fetal heart rate data. Additionally, a tocodynamometer can be used to measure the strength and frequency of contractions.

This method is often preferred in many clinical settings because it allows for continuous observation without the need for invasive procedures, making it safer and more comfortable for the mother and fetus during labor. The data gathered through external monitoring provide important information about the well-being of the fetus, helping healthcare providers make informed decisions throughout the labor process.

In contrast, internal monitoring involves the placement of a device inside the uterus, which requires rupturing the amniotic sac. Intrapartum monitoring refers to the monitoring that occurs during labor but is not specific to the method used, while antipartum monitoring relates to assessments made before labor begins.
