Question: What Does Toco Mean In Pregnancy?

What is Toco on a fetal 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 is Toco used for?

Objective. Tocodynamometry (Toco—strain gauge technology) provides contraction frequency and approximate duration of labor contractions, but suffers frequent signal dropout necessitating re-positioning by a nurse, and may fail in obese patients.

What does a contraction look like on monitor?

The monitor records the duration of contractions and the time between them but doesn’t tell you the strength of the contraction. Each contraction resembles a hill or a bell-shaped curve, starting low, rising slowly, and then returning to baseline.

What is a contraction on a Toco?

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.

Where should I place my Toco monitor?

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.

How does the Toco work?

Koala Toco is a small plastic disk with air inside that rests on the abdomen of a pregnant woman. When the uterus contracts, it pushes against the intrauterine wall and makes internal pressure rise. That pushes the air inside the Koala Toco and produces a signal.

How high are labor contractions?

Contractions in active labor generally last between 45 to 60 seconds, with three to five minutes of rest in between. In transition, when the cervix dilates from 7 to 10 centimeters, the pattern changes to where contractions last 60 to 90 seconds, with just 30 seconds to 2 minutes of rest between.

How do I know the difference between Braxton Hicks and real contractions?

Braxton Hicks contractions are irregular and infrequent. They usually last about 15 to 30 seconds (but sometimes as long as two minutes), and they should subside when you change positions. Real labor contractions are relatively regular and grow stronger, longer and closer together as you near labor.

How do you read the numbers on a contraction monitor?

The Y Axis of Fetal Monitoring These are beats per minute (bpm), which are measured in increments of 10 with markings every 30 beats. 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 do fetal accelerations mean?

Accelerations are transient increases in the FHR (Figure 1). They are usually associated with fetal movement, vaginal examinations, uterine contractions, umbilical vein compression, fetal scalp stimulation or even external acoustic stimulation.

What is acceleration in pregnancy?

Accelerations are short-term rises in the heart rate of at least 15 beats per minute, lasting at least 15 seconds. Accelerations are normal and healthy. They tell the doctor that the baby has an adequate oxygen supply, which is critical.

What does a Tocodynamometer measure?

A tocodynamometer is a device for monitoring and recording uterine contractions before and during labour. It consists of a pressure transducer that is placed over the fundus area of the uterus using a belt, and then records the duration of contractions and the intervals between them on a monitor or on graph paper.

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.

What do Braxton Hicks look like?

Women often describe Braxton Hicks contractions as feeling like mild menstrual cramps or a tightening in a specific area of the stomach that comes and goes. “I find them like a mild stitch that goes almost as quickly as it comes. Not painful but you’re definitely aware it’s there.
