Cardiotocography (CTG) is a continuous recording of the fetal heart rate obtained via an ultrasound transducer placed on the mother’s abdomen. CTG is widely used in pregnancy as a method of assessing fetal well‐being, predominantly in pregnancies with increased risk of complications.
Why do a CTG test during pregnancy?
The purpose of CTG recordings is to identify when there is concern about fetal well-being to allow interventions to be carried out before the fetus is harmed. The focus is on identifying fetal heart rate (FHR) patterns associated with inadequate oxygen supply to the fetus.
How early can you have a CTG?
CTG may be considered at gestations below 24+0 weeks following a multidisciplinary discussion with the woman regarding birth and neonatal management.
What is normal CTG in pregnancy?
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 much does CTG cost?
Normally, CTG Machine price in India ranges between INR 50k to INR 3 lakh.
Is NST and CTG same?
CTG during pregnancy refers to the performance of the non-stress-test (NST). The essence of the test is to determine whether an increase in fetal HR (acceleration) is recorded in the presence of fetal movements.
Does CTG harm baby?
Are there any side-effects or complications from cardiotocography? CTG does not use any radiation; it is considered a very safe test. Depending on the machine used, it may prevent you from being able to move around freely during labour.
How do you read a CTG baby?
- DR: Define risk.
- C: Contractions.
- BRa: Baseline rate.
- V: Variability.
- A: Accelerations.
- D: Decelerations.
- O: Overall impression.
What is abnormal CTG in Labour?
An abnormal CTG has two or more features which are non-reassuring, or any abnormal features. Further information about classifying FHR traces: If repeated accelerations are present with reduced variability, the FHR trace should be regarded as reassuring.
How can I check my baby's heartbeat at home?It’s possible to hear the heartbeat at home using a stethoscope. Unfortunately, you can’t hear it as early as you can with an ultrasound or fetal Doppler. With a stethoscope, a baby’s heartbeat is often detectable between the 18th and 20th week. Stethoscopes are designed to amplify small sounds.
Article first time published onWhat number is high for contractions?
Contractions can be described by frequency, duration, strength (amplitude), uniformity, and shape. 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.
Does everyone get a NST during pregnancy?
NST is a common test for pregnant women. Your doctor may use it to check the health of your baby after weeks 26 to 28 of pregnancy. Certain results may mean your doctor needs to monitor your baby, do more tests, or schedule delivery.
How long is a NST test?
Typically, a nonstress test lasts 20 minutes. However, if your baby is inactive or asleep, you might need to extend the test for another 20 minutes — with the expectation that your baby will become active — to ensure accurate results.
What happens if baby fails NST?
A non-stress test is noninvasive and does not pose any type of risk to the pregnant person or the fetus. If the test is failed, it usually indicates that more tests, further monitoring, or special care orders will be needed.
What can indicate fetal distress?
Fetal distress is diagnosed by reading the baby’s heart rate. A slow heart rate, or unusual patterns in the heart rate, may signal fetal distress. Sometimes fetal distress is picked up when a doctor or midwife listens to the baby’s heart during pregnancy.
What causes long labor?
Prolonged labor can result from a variety of different issues, such as fetal malpresentation, issues with uterine contractions, cervical dystocia or stenosis, and cephalopelvic disproportion. Both fetal malpresentation and cervical dystocia may result in obstructed labor.
How long do contractions last?
You have strong and regular contractions. Contractions help push your baby out. 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 is a normal contraction number?
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 are the stages of Labour?
There are three stages of labour. The first stage is when your cervix is opening and your baby is moving down the birth canal. The second stage is when your baby is being born and the third stage is when the placenta is delivered. Understanding the stages of birth can help you know what is happening during your labour.
What are the labor stages?
- Early Labor: The onset of labor until the cervix is dilated to 3-6 centimeters.
- Active Labor Phase: Continues from 3 cm until the cervix is dilated to 7 centimeters.
- Transition Phase – Continues from 7 cm until the cervix is fully dilated to 10 centimeters.
Can I hear my baby heartbeat with my phone?

What does NST look for?
A non-stress test (NST) looks at your baby’s heart rate over time (usually 20 to 30 minutes, but sometimes up to an hour). The monitor has two sensors that are placed on your belly with two belts that go around your waist. One sensor detects any contractions you may be having, even those you might not feel.
What is a stress test at 40 weeks pregnant?
The contraction stress test (CST) is a test to see how your baby might cope with contractions during labor. If recommended, the test is typically done near the end of pregnancy. To perform the test, your doctor will induce mild contractions.
