What is cardiotocography? Cardiotocography (CTG) measures your baby’s heart rate. At the same time it also monitors the contractions in the womb (uterus). CTG is used both before birth (antenatally) and during labour, to monitor the baby for any signs of distress.
How does a CTG measure contractions?
One transducer records the fetal heart rate using ultrasound and the other transducer monitors the contractions of the uterus by measuring the tension of the maternal abdominal wall (providing an indirect indication of intrauterine pressure). The CTG is then assessed by a midwife and the obstetric medical team.
How do contractions show on monitor?
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. Sometimes it’s easier to read printouts by looking at them sideways.
Can you see a contraction on an ultrasound?
On an ultrasound, a sonographer can observe contractions — the uterine wall thickens slightly. Most likely your facial grimaces would also signal that you’re having a contraction!
How do I know if its a contraction?
If you touch your abdomen, it feels hard during a contraction. You can tell that you’re in true labor when the contractions are evenly spaced (for example, five minutes apart), and the time between them gets shorter and shorter (three minutes apart, then two minutes, then one).
What number is considered a contraction?
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.
What does a normal CTG look like?
Normal antenatal CTG trace: The normal antenatal CTG is associated with a low probability of fetal compromise and has the following features: Baseline fetal heart rate (FHR) is between 110-160 bpm • Variability of FHR is between 5-25 bpm • Decelerations are absent or early • Accelerations x2 within 20 minutes.
How high do contractions get during labor?
It usually takes from 15 minutes to an hour for the cervix to dilate from 8 to 10 centimeters. Contractions are 2 to 3 minutes apart and last about 1 minute. You may feel pressure on your rectum and your backache may feel worse.
What are the warning signs of premature labor?
Signs and symptoms of preterm labor include:
- Regular or frequent sensations of abdominal tightening (contractions)
- Constant low, dull backache.
- A sensation of pelvic or lower abdominal pressure.
- Mild abdominal cramps.
- Vaginal spotting or light bleeding.

Can contractions feel like baby moving?
If your entire uterus is hard during the cramping, it’s probably a contraction. If it’s hard in one place and soft in others, those are likely not contractions—it may just be the baby moving around.
How do doctors check for contractions?
If you are having contractions, your doctor uses a tocodynamometer, which is attached to a band and held in place against your belly, to monitor and measure uterine contractions. This helps your doctor to determine the regularity and frequency of the contractions, which may indicate labor.
Can you tell if your dilated from an ultrasound?
Dilation and labor
You may have no signs or symptoms that your cervix has started to dilate or efface. Sometimes, the only way you’ll know is if your doctor examines your cervix at a routine appointment late in your pregnancy, or if you have an ultrasound.
What drug stops uterine contractions?
Doctors may try to stop or delay preterm labor by administering a medication called terbutaline (Brethine). Terbutaline is in a class of drugs called betamimetics. They help prevent and slow contractions of the uterus. It may help delay birth for several hours or days.
How do you feel 24 hours before labor?
As the countdown to birth begins, some signs that labor is 24 to 48 hours away can include low back pain, weight loss, diarrhea — and of course, your water breaking.
Can you be in labor and not know?
It’s very unlikely that you will suddenly go into labor without warning. Your body will let you know that you’re close to the big day, so you can make sure your hospital bag is packed, and be ready to go to the hospital when the time is right.
When should I start timing contractions?
Timing a contraction will begin when the contraction begins to build, start then, and when the contraction begins to wind down, stop. The length of a contraction is considered how long a contraction is from start to stop.
