A Detailed Explaination of Fetal Heart Rate Monitoring
During the birth of a fetus, a physician will often use a CTG monitor to record the heart rate of the fetus. Using the fetal heart rate (FHR) is important because it can tell the physician whether the fetus is growing at a healthy rate or whether there is a problem with the fetus. It can also help to detect burst-shaped heart sounds, which can be a sign of a problem.

During labour
During labour, your healthcare practitioner will check the heart rate of your baby to determine how well he or she is tolerating contractions. Your doctor will use a special stethoscope or Doppler device to record your baby's heartbeat. Typically, your baby's heart rate will be checked every 15 to 30 minutes in the first stage of labour.
If your baby's heart rate is not at the correct rate during labor, your doctor may recommend a cesarean delivery. During labour, your provider may also check your baby's heart rate more frequently during the second stage of labor. If your baby's heart rate fluctuates below 110 beats per minute, it may indicate a problem.
Variable decelerations are temporary dips in your baby's heart rate. These are typically not dangerous, but they may be a sign of reduced blood flow. These are considered normal if the baby is still dilated and before delivery.
Classification of normal and pathological CTGs
During labor, the classification of normal and pathological CTGs is a critical issue. It is a major challenge to accurately determine whether non-reassuring CTG patterns are serious enough to warrant intervention. However, there are methods available to increase the specificity of CTG Medical Paper readings.
The primary challenge is determining the risk profile of the mother and fetal status. The fetal heart rate (FHR) should be evaluated antepartum and intrapartum. It is important to determine whether there is evidence of intrapartum hypoxia.
If there is evidence of hypoxia, then there should be an immediate delivery of the fetus. The fetal blood analysis can confirm the pathological FHR patterns.
In order to decrease the false-positive rate, it is recommended that the CTG be recorded in a Medical record paper for a longer period of time. A fetal stimulation or Doppler sonography can also reduce the false-positive rate.

Detection of burst shaped heart sounds
Using a fetoscope and a stethoscope to listen for fetal heart rate monitoring may be as simple as a matter of seconds. Most hospitals have at least one or two handheld Dopplers in their fetal wards. The handheld devices are easy to use and they are not expensive. The big question is whether the fetus is healthy enough to avoid the need for monitoring.
During labor, women should be encouraged to ask questions about their baby's heart rate. While no one is going to tell you that your baby is going to have a heart defect, there are some conditions that make it more likely. Changing positions during labor can improve fetal heart rate monitoring.
The best fetal heart rate monitoring systems incorporate a fetoscope and stethoscope into one device. The fetoscope should be placed over the fetal back near the baby's head and the stethoscope should be positioned on the abdomen.
Classification of FHR decelerations
During labor, obstetricians have relied on visual inspection of fetal heart rate (FHR) patterns to determine fetal health. There are several different forms of fetal decelerations. Each type has different clinical implications. It's important to understand which decelerations are most likely to cause problems.
Variable decelerations are characterized by a rapid fall in fetal heart rate. This is usually seen during labor and is a sign that there is an obstruction to fetal blood flow. Usually, the deceleration occurs after a few contractions. It may last for more than 60 seconds. This type of deceleration is most likely to occur with decreased amniotic fluid volume.
Variable decelerations are most likely to occur during the first stage of labor. However, they may also occur in the second or third stage.
qCTG decision-support system
Using a decision-support system for fetal heart rate monitoring (qCTG) can improve the identification of fetal features and improve the interpretation of ctg recording paper traces. The software alerts clinicians in real time when abnormalities are detected in the CTG. It may improve clinical decision-making, reduce the need for intervention, and minimize the risk of adverse birth outcomes.
A decision-support system for fetal heart monitoring (qCTG) is a computer-assisted analysis tool that can be used by obstetricians to identify fetal features and monitor fetal status. It can help clinical teams to make decisions about escalation or treatment, and may even help to increase operative delivery rates.
The main challenge in using CTG is to determine whether a CTG pattern is non-reassuring and if it needs intervention. This can be accomplished by using an expert system. Expert systems use artificial intelligence to synthesize expert opinion with patient data, guide the user toward a diagnosis, and recommend treatment. Some systems use neural networks, rule-based algorithms, or both.
