Fetal Circulation01:14

Fetal Circulation

1.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Holter Monitor: 24-Hour Monitoring

53
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Area of Science:

  • Biomedical Engineering
  • Cardiology
  • Signal Processing

Context:

  • Fetal ECG monitoring is crucial for assessing fetal well-being in utero.
  • Current ultrasonic Doppler methods are complex, specialized, and costly.
  • There is a need for more accessible fetal monitoring technologies.

Purpose:

  • To develop and evaluate a novel fetal ECG detection system using maternal abdominal electrodes.
  • To overcome the limitations of existing fetal heart rate monitoring techniques.
  • To provide a low-cost, user-friendly, and effective fetal ECG monitoring solution.

Summary:

  • A fetal ECG detection system is introduced, utilizing electrodes placed on the maternal abdomen.
  • The system amplifies and filters weak fetal ECG signals from the maternal abdominal electrode.
  • Signals are transmitted wirelessly (WiFi) to a host computer for analysis using adaptive filtering algorithms.

Impact:

  • This technology offers a more feasible and convenient approach to fetal ECG monitoring.
  • Reduced operational complexity and cost make fetal monitoring more accessible.
  • Potential to improve prenatal care through real-time fetal heart assessment.
