EEG monitor of fetal health

摘要

A method for predicting health compromise in a fetus comprises acquiring one or more EEG signals and a fetal heart rate (FHR) signal from the surface of the head of a fetus; and determining the spectral edge frequency (SEF) of the one or more EEG signals. A repetitive temporal correlation between the FHR signal and the SEF of the one or more EEG signals is indicative of fetal health compromise. A system for detecting the correlation between FHR signal and the SEF of the one or more EEG signals and predicting fetal health compromise is also described.

1. A method for the early prediction of fetal health compromise due to fetal hypoxia/asphyxia, comprising:
(a) acquiring and identifying patterns in a Fetal Heart Rate (FHR) signal, wherein identifying patterns in the FHR signal comprises determining minima of the FHR signal and first time intervals between said minima; (b) acquiring one or more electroencephalogram (EEG) signals from at least one sensor placed on the surface of the head of a fetus and identifying patterns in the one or more EEG signals by performing an analysis based on a spectral edge frequency (SEF) of the one or more EEG signals, wherein identifying patterns in the one or more EEG signals comprises determining maxima of the SEF of the one or more EEG signals and second time intervals between said maxima; (c) determining a repetitive temporal correlation between the patterns in the FHR signal and the patterns in the one or more EEG signal by determining a correlation value between the first time intervals and the second time intervals; and (d) predicting the fetal health compromise based on the repetitive temporal correlation.
