What’s Toco on a baby monitor?

Cardiotocography (CTG) is a technical means of recording (-graphy) the fetal heartbeat (cardio-) and the uterine contractions (-toco-) during pregnancy, typically in the third trimester. The machine used to perform the monitoring is called a cardiotocograph, more commonly known as an electronic fetal monitor.

What are normal Toco numbers?

Table 1

Variable Mean Range
Duration of monitoring (min) 137 48.6 – 345.9
IUPC contractions 38.3 8 – 95
EHG contractions 37.7 8 – 94
Toco contractions 26.4 1 – 64

What Toco number is considered a contraction?

The intensity of Braxton Hicks contractions varies between approximately 5-25 mm Hg (a measure of pressure). For comparison, during true labor the intensity of a contraction is between 40-60 mm Hg in the beginning of the active phase.

How high do contractions go on Toco?

During normal labor, the amplitude of contractions increases from an average of 30 mm Hg in early labor to 50 mm Hg in later first stage and 50 to 80 mm Hg during the second stage.

What should contractions be on monitor?

Uterine monitoring is based on the idea that the frequency of contractions per hour increases as a woman gets closer to delivery. As labor progresses, contractions get longer, harder, and stronger. If the machine measures four or less contractions per hour, you’re probably not in labor.

What is a strong contraction?

You have strong and regular contractions.

When you’re in true labor, your contractions last about 30 to 70 seconds and come about 5 to 10 minutes apart. They’re so strong that you can’t walk or talk during them. They get stronger and closer together over time.

What do strong contractions look like on monitor?

The red indicator on the bottom tracing shows the strength of a contraction, measured in millimeters of mercury (mmHg). 6 The higher the number, the stronger the contraction.

What is Toco during labor?

Introduction. Women in labor are traditionally monitored with the tocodynamometer (TOCO), which is based on the pressure force produced by the contorting abdomen during uterine contractions. The contractions are measured by a pressure transducer placed on the patient’s abdomen.

How do you measure the strength of contractions?

The strength of the contraction is measured from the baseline (when the uterus is relaxed) to the peak of the contraction and is recorded in units-one unit is the amount of pressure it takes to raise a column of mercury one millimeter.

How do I monitor my baby during labor?

There are different ways to monitor baby, including:

  1. Pinard stethoscope, a type of ear trumpet put on your abdomen to let the midwife hear and count baby’s heartbeat.
  2. Doppler, a small portable machine using ultrasound through a small transmitter-receiver on your abdomen to pick up baby’s heartbeat.

How are contractions measured on a monitor?

During labor, uterine contractions are usually monitored along with the fetal heart rate. A pressure-sensitive device called a tocodynamometer is placed on the mother’s abdomen over the area of strongest contractions to measure the length, frequency, and strength of uterine contractions.
