From: VO2 and VCO2 variabilities through indirect calorimetry instrumentation
Example of a vVO2 ( f ) power spectrum in (ml/breath) 2 /Hz. A subject underwent the clino-orthostatic maneuver. Graph (a) shows the vVO2(f) outlined in black that corresponds to the clino stage. The power spectrum function outlined in gray corresponds to the orthostatic stage. Graph (b) shows the power spectra for the continuous instant flow f(t).
