Your question: How are contractions monitored?

How do hospitals monitor contractions?

The monitoring is usually performed in a doctor’s office or hospital. A nurse will wrap a belt around your waist and attach it to a machine called a tocodynamometer. The machine records the frequency and length of your contractions. Your doctor may also recommend monitoring your contractions at home.

What do contractions look like on the monitor?

Contractions are in red. When you’re looking at the screen, the fetal heart rate is usually on the top and the contractions at the bottom. When the machine prints out graph paper, you’ll see the fetal heart rate to the left and the contractions to the right.

How do you monitor frequency of contractions?
