Fetal Circulation01:14

Fetal Circulation

4.8K
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...

    This study presents a rapid fetal electrocardiogram (ECG) acquisition system for precise 24-bit digital signal conversion. The system offers low power consumption and high accuracy for non-invasive fetal monitoring.

    Area of Science:

    • Biomedical Engineering
    • Medical Devices
    • Signal Processing

    Background:

    • Accurate fetal electrocardiogram (ECG) monitoring is crucial for assessing fetal well-being during pregnancy.
    • Existing systems may face challenges with data transmission rates, power consumption, and precision.
    • A need exists for an efficient and high-precision system for acquiring fetal ECG signals from the maternal abdominal wall.

    Purpose of the Study:

    • To design and develop a rapid fetal ECG signal acquisition system.
    • To improve data transmission rates and maintain high precision in fetal ECG signal collection.
