In embodiments of the present disclosure, a device and method for determining the heart rate of a fetus and the heart rate variability of a pregnant woman and fetus is envisaged. The method comprises: generating a spectral transform from a waveform representative of an individual-specific hemodynamic parameter; determining a candidate residual signal included in a region independent of the excluded region of the spectral transformation; identifying candidate residual signals from among the candidate residual signals; comparing the candidate residual signal with a target signal representative of the oxygen level present in the blood flow of the individual, the target signal derived from a hemodynamic parameter; and upon identifying an inverse correlation between the candidate residual signal and a target signal of the individual, determining that the candidate residual signal is associated with a heart rate of a fetus located in the individual.

In an embodiment of the present disclosure, a device and method for determining a fetal heart rate and heart rate variability of a pregnant woman and a fetus are contemplated. The method includes generating a spectral transform from a waveform representing a hemodynamic parameter specific to an individual, determining a candidate residual signal contained within an area independent of an excluded area of ​​the spectral transform, identifying a candidate residual signal from the candidate residual signals, comparing the candidate residual signal with a target signal representing an oxygen level present in the individual's bloodstream, the target signal being derived from the hemodynamic parameter, and determining that the candidate residual signal is associated with the heart rate of a fetus located within the individual in response to identifying an inverse correlation between the candidate residual signal and the target signal of the individual.

Electrophysiologic biomarkers for prognostication of neurological outcome are described herein. An inverse correlation was found between timing of a cortical spreading depolarization (SD) wave and neurological outcome as tested at 24 hours post-CPR. Additionally, a minor image of this SD was identified as a “repolarization (RP) wave.” Quantifying features of SD and RP during cardiac arrest and cardiopulmonary resuscitation (CPR) provide important metrics for diagnosis and prognosis of neurological injury from hypoxia-ischemia and can serve as an early prognostication tool for predicting outcome at subsequent days after successful CPR. This discovery may also allow for novel therapeutic interventions to improve neurological recovery after hypoxia-ischemia insults.
