What TOCO Number is a Strong Contraction?
Introduction
The TOCO number is key indicator of a contraction’s duration and frequency. Understanding the significance of the TOCO number provides a foundation for effective maternal and fetal care. In this article, we’ll explain what a TOCO number indicates and break down the TOCO number ranges for each contraction stage.
What is TOCO on a Fetal Monitor?
A TOCO (tocodynamometer) is used in fetal monitoring to measure uterine contractions during labor. The TOCO number represents the timing and patterns of uterine contractions. By understanding this number, providers can assess the pregnancy and monitor the baby’s health.
The TOCO number typically ranges from 0 to 100, though the the reading is relative to each patient.
What TOCO Number is a Strong Contraction?
Braxton Hicks Contractions
Braxton Hicks contractions are uterine contractions that occur typically in the second trimester. These contractions are mild and less intense than active labor contractions and do not increase in intensity or frequency over time.
Typically, the TOCO number ranges between 5-25 mmHg.
Active Labor Contractions
Active labor contractions can vary depending on factors such as intensity of the contractions and stage of labor. During active labor, the TOCO number tends to be higher than Braxton Hicks contractions, reflecting more frequent contractions.
At this stage, the TOCO number may range from 40 to 70 mmHg.
Second Stage of Labor Contractions
During the second stage of labor, the contractions are typically strongest and most frequent, as the body works to push the baby through the birth canal.
The TOCO number can increase to anywhere between 60-100 mmHg.
