How to Tell If Your Having Contractions on the Monitor
If you experience contractions, plan the duration and time between contractions. It`s time to call Labor & Delivery for more instructions and come for evaluation once the contractions are regularly in frequency and: The CTG band is connected to a machine that interprets the signal coming from the plates. The baby`s heart rate can be understood as a beat or pulsation that the machine produces. Some mothers may find this distracting or disturbing, but it`s possible to turn down the volume if the noise bothers you. The device also provides an impression that shows the baby`s heart rate over a period of time. It also shows how the heart rate changes with your contractions. If you suffer from CTG before going to labour, you may be asked to press a button on the machine every time the baby moves. At this point, you don`t have any contractions, so the CTG only monitors the baby`s heart rate. The term appeared in 1872 when an English physician named John Braxton Hicks described contractions that occur before actual birth. Also known as “false contractions” or “exercise contractions,” these contractions can begin as early as the second trimester, but are more common in the third trimester.
There is no “proven” method that works for everyone. If you feel Braxton Hicks contractions, try: Zhao Z, Zhang Y, Deng Y. A comprehensive analysis of fetal heart rate signal characteristics for an intelligent assessment of fetal status. CWY. 2018;7(8):223. doi:10.3390/jcm7080223 It is normal for a baby`s heart rate to vary between 110 and 160 beats per minute. This is much faster than your own heart rate, which is about 60-100 beats per minute. A heart rate in your baby that does not vary or is too low or too high may mean that there is a problem. Your doctor or midwife may need to perform further tests to check this. The image below shows the equipment used for a CTG. It usually stands at your bedside while you are being watched.

Start a conversation with your provider about fetal monitoring during your prenatal visits. Ask them how they use fetal monitoring during labour, including when they would recommend continuous or internal fetal monitoring. EFM uses ultrasound waves to hear your baby`s heart. Your midwife uses a machine called a transducer, which is held against your abdomen, or a small electrode attached to your baby`s scalp or buttocks if the position of your baby`s seat is. Internal follow-up only takes place in certain situations during work. A thin wire from the sensor is placed through your vagina and cervix into your uterus. It is attached to your baby`s scalp.
Alfirevic Z, Devane D, Gyte GM, Cuthbert A. Continuous cardiotocography (CTG) as a form of electronic fetal monitoring (EFM) for fetal assessment during labour. Cochrane Database Syst Rev. 2017;2(2):CD006066. doi:10.1002/14651858.CD006066.pub3 Cardiotocography (CTG) is used during pregnancy to monitor fetal heart rate and uterine contractions. It is most often used during the third trimester and its purpose is to monitor the well-being of the fetus and allow the early detection of fetal stress. An abnormal GTC may indicate the need for further investigation and possible intervention. No one type of fetal monitoring will suit everyone. The frequency with which it is necessary to check the baby and contractions will vary from person to person – and even from birth to labor with the same person. If your work is considered high-risk, you will likely need to perform ongoing fetal monitoring. This involves checking how far their cervix is dilated, the position of your baby`s head and how far in the birth canal they are.
Your doctor`s preference may also affect the type of monitoring you have. Talk to your doctor about what they usually use. A tiny electrode is inserted through your vagina onto your baby`s scalp. A catheter is also placed in your uterus, or an external pressure gauge is attached to your abdomen to measure the strength of your contractions. Fetal monitoring can be performed in several ways, depending on the needs of the patient and the capabilities of the facility. Physically, fetal monitoring can be performed outdoors or indoors. The timing of monitoring can be continuous or intermittent. Cardiotocography is usually called “CTG” by doctors and midwives. It can be used to monitor a baby`s heart rate and a mother`s contractions during pregnancy. Electronic fetal monitoring uses special devices to continuously measure your baby`s heart rate response to contractions.
This way, your doctor can assess how your baby is handling labor. CTG is most often performed outdoors. This means that the equipment used to monitor the baby`s heart is placed on the mother`s abdomen (abdomen). An elastic belt is placed around the mother`s abdomen. It has two round, flat plates the size of a tennis ball that come into contact with the skin. One of these plates measures the baby`s heart rate. The other assesses the pressure on the abdomen. In this way, it is able to show when each contraction occurs and an estimate of its strength.
They are of variable duration and may have nothing to do with uterine contractions. Doctors recommend monitoring throughout labour (continuously) in a high-risk pregnancy. For example, a high risk may mean that you have preeclampsia or type 1 diabetes, or that your baby has a health problem. Pregnancy can become a high risk during labor if a problem occurs. Then the baby`s heart rate would be checked all the time. When connected to an external monitor, you can move around on your bed or on a nearby chair. However, you cannot move freely unless telemetry monitoring is used. Stout MJ, Cahill AG. Electronic fetal monitoring: past, present and future. Perinatology clinics. 2011;38(1):127-142. doi:10.1016/j.clp.2010.12.002 Changes in the baby`s heart rate that occur with contractions form a pattern.
Some changes in this pattern may indicate a problem. If the test results indicate that your baby has a problem, your doctor may decide to give birth immediately. This may mean that you will need a caesarean section or assisted delivery with tweezers. Cardiotocography (CTG) measures your baby`s heart rate. At the same time, it also monitors contractions in the uterus (uterus). CTG is used both before birth (prenatal) and during labour to monitor the baby for signs of stress. By looking at different aspects of the baby`s heart rate, doctors and midwives can see how the baby is doing. Braxton Hicks contractions are not considered real labor because they do not cause cervical change. Remember that if your contractions don`t increase in intensity or frequency, you`re probably experiencing Braxton Hicks contractions. Unlike real contractions, Braxton Hicks contractions are: Ayres-de-Campos D. Electronic fetal monitoring or cardiotocography, 50 years later: what`s in a name? At J Obstet Gynecol.
2018;218(6):545-546. doi:10.1016/j.ajog.2018.03.011 Remember – Braxton Hicks contractions are a normal physiological event during pregnancy. Most of the time, they are bearable and once you start experiencing them, you are usually close to the end of your pregnancy. Always consult your doctor if you are worried. This type of fetal control uses a transmitter on your thigh to transmit the baby`s heart sounds to the nurse`s service via radio waves. However, equipment is not available in all hospitals. An advantage of electronic monitoring over the fetoscope method was that it could be performed without the provider having to be at the bedside. Here`s a brief overview of how electronic fetal monitoring is used and how to interpret what you see (and hear) on the monitor. Fetal heart monitoring is a way to check your baby`s (fetus) heart rate during labor. Heart rate is a great way to tell if your baby is okay. This can show if there is a problem. Once you have evaluated all aspects of the GTC, you need to determine your overall impression.
Most experts say that electronic fetal monitoring is not necessary in many cases. Wondering if electronic fetal monitoring will be necessary for you – or do you hope to avoid it altogether? Talk to your doctor about your options. All fetuses experience stress during the labor process, as a result of uterine contractions, which reduce fetal perfusion. While fetal stress is to be expected during labor, the challenge is to absorb pathological fetal loads. When you look at the screen, the fetal heart rate is usually at the top and the contractions at the bottom. When the machine prints graphic paper, you can see the fetal heart rate on the left and contractions on the right. It is generally suggested that women determine whether contractions are regular in frequency, intensity, and duration. For example, it is not a real job if: Individual contractions are considered spikes on the part of CTG monitoring of uterine activity.. .
