How do you measure intensity of contractions?

The intensity of the contractions can be estimated by touching the uterus. The relaxed or mildly contracted uterus usually feels about as firm as a cheek, a moderately contracted uterus feels as firm as the end of the nose, and a strongly contracted uterus is as firm as the forehead.

What is the normal contraction intensity?

In a normal labor, one contraction every two to three minutes or less than five contractions in a 10 minute period is ideal. A uterus must rest between contractions, having sufficient uterine resting tone (soft to the touch), and uterine resting time (about one minute).

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.

What is a contraction on Toco?

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.

What does Toco mean on contraction monitor?

The pressure-sensitive contraction transducer, called a tocodynamometer (toco), measures the tension of the maternal abdominal wall – an indirect measure of the intrauterine pressure.

What does Toco mean?

Toco-: Prefix meaning childbirth. For example, tocolysis is the slowing or halting of labor. Sometimes spelled tok-, toko-.

What does the Toco reading mean?

How do you count contractions?

When timing contractions, start counting from the beginning of one contraction to the beginning of the next. The easiest way to time contractions is to write down on paper the time each contraction starts and its duration, or count the seconds the actual contraction lasts, as shown in the example below.

How do you time a contraction?

Timing Contractions Decide what timing tools to use. Start timing at the beginning of a contraction. Write down the time the contraction starts. Write down the time the contraction ends. Write down the time when the next contraction begins.

What is the duration of contraction?

The average contraction can vary in length, intensity and frequency depending on your stage of labor: Early labor: Each contraction usually lasts about 30 to 45 seconds. They may start as much as 20 minutes apart, but will become progressively shorter as this phase ends.

What is high uterine resting tone?

Hypertonus in Hg or MVU. Definition. elevated uterine resting tone greater than 20 to 25 mm Hg between or after contractions, depending on the type of intrauterine pressure catheter (IUPC) used, or peak pressure of the uterine contraction greater than 80 mm Hg (in the absence of pushing), or Montevideo units (MVU) greater than 400–440.
