187 Figure 5.26 Sympathetic and parasympathetic mixture plots of HR using Haar wavelet (COPD subject in 5 min rest, breathing at 16bpm). Figure 5.27 Normalized sympathetic and parasympathetic mixture plots of HR using Haar wavelet (COPD subject in 5 min rest, breathing at 16bpm).
188 5.2.7 Time-Frequency Analysis (Wavelet) of Blood Pressure Variability In order to experiment with analyzing COPD BPV signals, the BP IIBI signal is used. One example of the BP IIBI signals is from a COPD subject resting and paced-breathing at 16 breaths per minute. Figure 5.28 illustrates the BP IIBI and its power spectrum plots for the case of a file from a COPD subject paced breathing at 16 bpm during a 5 minutes rest period. The BP analysis was also performed using the five different wavelet distributions (Morlet, Meyer, Daubechies 4, Mexican Hat and Haar) with the same specifications (length of analysis window equals to 200 and the length of FFT analysis of 256). Figure 5.28 Plot of blood pressure IBI and its power spectrum using Fourier transform.
