Fetal Circulation

5.0K
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...

Area of Science:

  • Obstetrics and Gynecology
  • Biomedical Engineering
  • Digital Health

Background:

  • Cardiotocography (CTG) has been a standard for fetal well-being assessment since the 1960s.
  • Despite decades of use, progress in automated CTG analysis lags behind other fields due to a lack of standardized, open-access data.
  • This hinders collaboration between clinicians and technicians, impeding clinically relevant advancements.

Purpose of the Study:

  • To introduce a novel, open-access database of digital intrapartum cardiotocographic (CTG) recordings.
  • To provide a common ground for researchers to compare results and advance automated CTG analysis.
  • To facilitate a better understanding of the field from both clinical and technical viewpoints.

Main Methods:

  • Compilation of 552 intrapartum CTG recordings from April 2010 to August 2012.
  • Recordings were selected from 9164 available, focusing on clinical and technical relevance.
  • Data includes CTG traces, time to delivery, second stage of labor duration, and associated clinical/biochemical markers.

Main Results:

  • The database comprises 552 high-quality intrapartum CTG recordings.
  • It includes detailed clinical and biochemical data, facilitating comprehensive analysis.
  • The dataset is designed to support the development and validation of new CTG analysis methods.

Conclusions:

  • The presented open-access CTG database offers a valuable resource for the research community.
  • It aims to standardize research and accelerate progress in automated fetal monitoring.
  • Understanding the database's context and limitations will empower researchers to utilize it effectively.
