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...

Pulse rhythm

872
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Area of Science:

  • Medical Technology
  • Biomedical Signal Processing
  • Machine Learning in Healthcare

Background:

  • Cardiotocography (CTG) is the primary non-invasive method for fetal health monitoring.
  • Automated CTG analysis faces challenges in interpreting complex fetal heart rate (FHR) dynamics, particularly for suspicious cases and different labor stages.

Purpose of the Study:

  • To develop and validate a machine-learning-based classification model for CTG analysis.
  • To improve the interpretation accuracy of fetal heart rate patterns during different stages of labor.

Main Methods:

  • A machine learning model was developed and applied separately to the first and second stages of labor.
  • Classifiers including Support Vector Machine (SVM), Random Forest (RF), Multi-layer Perceptron (MLP), and Bagging were utilized.
  • Model performance was evaluated using accuracy, sensitivity, specificity, and ROC-AUC.

Main Results:

  • SVM and Random Forest classifiers demonstrated superior performance compared to others.
  • For suspicious cases, SVM and RF achieved accuracies of 97.4% and 98%, respectively, with high sensitivity and specificity.
  • In the second stage of labor, SVM and RF achieved accuracies of 90.6% and 89.3%, respectively.

Conclusions:

  • The proposed machine learning classification model is efficient for CTG analysis.
  • The model shows potential for integration into automated decision support systems for fetal health monitoring.
