Abstract

Fetal Heart Rate Decelerations Evaluated by Hypoxia Index

Highlights

  • Fetal heart rate patterns, including early, late and variable decelerations [1,2] could be detected by computer, fetal outcome was expected by doctor’s subjective decision, including controversy interpretation and observer differences in fetal heart rate (FHR) pattern analysis, numeric and objective method was mandatory by computer analysis of FHR changes, where clinical Apgar score and umbilical arterial pH (UApH) were predicted using regression equations of computer diagnosis, Apgar score and UApH obtained in FHR and neonatal studies, numeric outcome is obtained automatically, where long-term outcome numerization was needed to diagnose the outcome [3]

  • No FHR acceleration is detected against sharp fetal movement spiks with 2sec interval, and no FHR change was detected by computer analysis as neither deceleration nor acceleration with moderate variability developed, no pathologic change was diagnosed

  • Duration of deceleration and nadir heart rate are found in the computerized calculation of FHR score [11], which was limited in 5min, while hypoxia index is determined in full course of fetal monitoring

Summary

Introduction

Fetal heart rate patterns, including early, late and variable decelerations [1,2] could be detected by computer, fetal outcome was expected by doctor’s subjective decision, including controversy interpretation and observer differences in FHR pattern analysis, numeric and objective method was mandatory by computer analysis of FHR changes, where clinical Apgar score and UApH were predicted using regression equations of computer diagnosis, Apgar score and UApH obtained in FHR and neonatal studies, numeric outcome is obtained automatically, where long-term outcome numerization was needed to diagnose the outcome [3]. Attending doctor should receive mechanical results of computer output and clinical Apgar score obtained using regression equation, e.g. FHR score as well as predicted Apgar score, umbilical arterial blood pH(UAPH) and outcomes directly and rapidly by cellular phone or computer local area network (LAN), which promoted correct fetal management
