Abstract

Fetal heart activity is a vital measurement to assess the well-being of fetus throughout its intrauterine lifetime and mostly at the time of delivery. As it is a fact that the fetal heart rate interpretations are done manually, the readings are highly inaccurate and found to be subjective. Automated CTG analysis has been adopted as the most capable way to handle these problems of CTG. In this scope, CTG-OAS, an open software is used for fetal heart rate analysis. This software analyses the fetal heart rate and extracts the features of heart rate variability for further analysis. The results obtained are validated with those derived from the pH values of the cortical blood samples of delivered babies. The sympathetic and parasympathetic control on fetal heart rate and its relation with the fetal oxygenation is studied and analyzed for early detection of fetal distress.
