Results of empirical mode decomposition (EMD) and normalized Hilbert transform (NHT) of arterial blood pressure (ABP) waveform. It includes (a) original ABP waveform, (b) intrinsic component of ABP (IMF1-4 and residue), (c) frequency modulation (FM) of IMF4, instantaneous frequency (IF) of IMF4, and instantaneous pulse rate (iPR) within 5 seconds for example.
