In embodiments of the present disclosure, a device and method for determining a heart rate of a fetus and a heart rate variability of the pregnant woman and the fetus are contemplated. The method includes generating a spectral transform from a waveform representative of a hemodynamic parameter specific to the individual, determining candidate remnant signals included in an area independent of exclusion areas of the spectral transform, identifying a candidate remnant signal from the candidate remnant signals, comparing the candidate remnant signal with a target signal representative of oxygen levels present in blood stream of the individual, the target signal is derived from the hemodynamic parameter, and determining that the candidate remnant signal is associated with a heart rate of the fetus that is disposed in the individual upon identifying an inverse correlation between the candidate remnant signal and the target signal of the individual.
