Evaluation of Neonatal Acute Hypoxia at Delivery Using Fetal Physiology and Eucapnic pH Assessment

This study aims to improve understanding of how fetuses respond to oxygen deprivation during labor by re-evaluating cardiotocography (CTG) recordings using a physiology-based interpretation approach and comparing these findings with umbilical cord blood gas measurements at birth, including eucapnic pH assessment.

The study will include term pregnancies and combines retrospective data analysis with prospective enrollment. Researchers will investigate whether physiology-based CTG interpretation can better identify signs of fetal compromise and whether eucapnic pH may improve the distinction between respiratory and metabolic acidosis. Findings may contribute to improving fetal monitoring strategies and the assessment of newborn condition at birth.
