Some monitors restrict your movements. It should only be used if the external monitoring is problematic, the quality of the recording is poor, or in a twin pregnancy. It should not be used if you are HIV positive or hepatitis C positive. This test would be done if the doctors need more information than continuous monitoring provides. Sometimes this test needs to be repeated. The result will indicate if the baby needs to be born immediately. Learn more here about the development and quality assurance of healthdirect content.

Here's what she'll be listening for: "Baseline" heart rate: This is your baby's heart rate between contractions when he's not moving normal is between and beats per minute. Heart rate during and shortly after contractions: This will give your provider a sense of how your baby is tolerating labor. Here's what studies show: Mixed results.

Topic Overview What is fetal monitoring during labor? Monitoring may be done all the time during labor continuous or at set times intermittent.
How is it done? When your baby's heartbeat is not being checked, you may be able to walk around. When might you have each type of monitoring? What are the benefits of each type of monitoring? Intermittent You aren't attached to wires all the time. So you can leave the bed and walk around during labor. It can reassure you and your partner that the labor is going well. It can show the doctor or nurse-midwife that labor can go on at its own pace.
Continuous It can reassure you and your partner that the labor is going well. It can show a problem right away. What are the risks of each type of monitoring? Intermittent This kind of monitoring is very safe. The baby's heart rate can be heard as a beating or pulsing sound which the machine produces. Some mothers can find this distracting or worrying but it is possible to turn the volume down if the noise bothers you. The machine also provides a printout which shows the baby's heart rate over a certain length of time.
It also shows how the heart rate changes with your contractions. If you have CTG before you are in labour you may be asked to press a button on the machine every time the baby moves. At this time you will not be having any contractions so the CTG will only monitor the baby's heart rate. Occasionally during labour, if a signal can't be found using the external monitor, or when monitoring is more important, internal monitoring can be used.
For internal monitoring, a small, thin device called an electrode is used. This is inserted through the vagina and neck of the womb which will be opening during labour and placed on the baby's scalp. This device records the baby's heart rate. If you have a twin or higher multiples pregnancy, internal monitoring can only be used on the baby closest to the neck of the womb.
Additionally internal monitoring can only be used when the baby is going to be delivered head first. Internal monitoring will not work on a breech bottom or foot first presentation.
CTG uses sound waves called ultrasound to detect the baby's heart rate. Ultrasound is a high-frequency sound that you cannot hear but it can be sent out emitted and detected by special machines. Ultrasound travels freely through fluid and soft tissues. However, ultrasound bounces back as 'echoes' it is reflected back when it hits a more solid surface. For example, the ultrasound will travel freely through blood in a heart chamber. But, when it hits a solid valve, a lot of the ultrasound echoes back.
Another example is that when ultrasound travels though bile in a gallbladder it will echo back strongly if it hits a solid gallstone.
So, as ultrasound 'hits' different structures in the body, of different density, it sends back echoes of varying strength.
