Types of Fetal Heart Rate Monitoring Systems: Fetal Heart Rate Machine

Fetal Heart Rate Machine Technology Explained

Fetal heart rate monitoring is a crucial aspect of obstetric care during pregnancy, labor, and delivery. The choice of monitoring system depends on the clinical need, patient comfort, and the skill level of the healthcare provider. In this section, we will explore the different types of fetal heart rate monitoring systems, their advantages, and disadvantages.

Electronic Fetal Monitoring (EFM)

Electronic fetal monitoring is a non-invasive method that uses a sensor to record the fetal heart rate in conjunction with the mother’s contractions. EFM is commonly used during labor, especially in low-risk pregnancies. The system consists of two internal sensors attached to the mother’s abdomen, one for measuring the fetal heart rate and the other for detecting contractions. The readings are displayed on a monitor, allowing healthcare providers to assess fetal well-being and identify any potential issues.

Electronic fetal monitoring has both advantages and disadvantages.

  • Advantages: provides real-time data, allows for continuous monitoring, and enables healthcare providers to detect early signs of fetal distress.
  • Disadvantages: may require hospital admission, can cause discomfort or pain for the mother, and may lead to unnecessary interventions.

Intermittent Auscultation (IA)

Intermittent auscultation is a traditional method that involves listening to the fetal heart rate with a Doppler device or a fetoscope. This technique is often used in low-risk pregnancies and in the early stages of labor. Healthcare providers typically check the fetal heart rate every 30 minutes to 1 hour during the first stage of labor. IA is a less invasive and less expensive method compared to EFM.

Advantages and Disadvantages of Intermittent Auscultation:

Advantages Disadvantages
Invasive, less expensive, and does not require hospital admission May not detect early signs of fetal distress, requires skilled healthcare providers

Internal Fetal Monitoring

Internal fetal monitoring involves inserting sensors or catheters into the woman’s uterus to track the fetal heart rate. This method is typically used in high-risk pregnancies or when the fetal heart rate is difficult to obtain through external methods. Internal monitors provide more accurate readings, but they also carry a higher risk of complications, such as infection or umbilical cord prolapse.
Internal fetal monitoring can be performed in two ways:

  • Catheter method: involves inserting a catheter through the cervix into the uterus.
  • Transabdominal scalp electrode method: involves inserting a thin electrode into the fetal scalp to measure the heart rate directly.

External Fetal Monitoring

External fetal monitoring is a non-invasive method that uses sensors placed on the mother’s abdomen to record the fetal heart rate and contractions. This technique is commonly used in low-risk pregnancies and during the first stage of labor.

Important Considerations:

When choosing a fetal heart rate monitoring system, healthcare providers should consider the individual needs of each patient, the clinical context, and the potential risks and benefits associated with each method.

Wearable Fetal Heart Rate Monitors

Wearable fetal heart rate monitors are portable devices that record the fetal heart rate remotely using sensors attached to the mother’s clothing or abdomen. These devices offer a non-invasive and comfortable alternative to traditional monitoring methods. Wearable monitors can be used during prenatal appointments, during labor, or at home.

Advantages:

Wearable fetal heart rate monitors enable mothers to track their baby’s heart rate remotely, providing real-time data, and enabling healthcare providers to monitor fetal well-being continuously.

Examples of Fetal Heart Rate Tracings and Interpretation

Understanding fetal heart rate tracings is a crucial aspect of prenatal care, as it helps healthcare providers monitor the well-being of the fetus and identify any potential issues. Fetal heart rate tracings are a graphical representation of the fetal heart rate over a specific period, often in relation to contractions.

Normal Fetal Heart Rate Tracings

Normal fetal heart rate tracings are typically characterized by a baseline rate of 110-160 beats per minute (bpm), with occasional accelerations and decelerations.

| Fetal Heart Rate Tracing | Baseline Rate | Accelerations | Decelerations |
| — | — | — | — |
| Tracing 1: Normal Fetal Heart Rate Tracing | 120 bpm | Accelerations in fetal heart rate occur in response to fetal movement, which can be seen as increases in heart rate above 15 bpm lasting at least 15 seconds. | Decelerations are typically short-term and may be seen in response to contractions. |
| Tracing 2: Fetal Acceleration | 140 bpm | Fetal accelerations are increases in fetal heart rate that occur above 15 bpm lasting at least 15 seconds and are often seen in the face of fetal movement. | None observed. |

Abnormal Fetal Heart Rate Tracings

Abnormal fetal heart rate tracings can indicate potential issues with fetal well-being. It’s essential for healthcare providers to interpret these tracings carefully and in conjunction with other prenatal information.

| Fetal Heart Rate Tracing | Baseline Rate | Accelerations | Decelerations |
