Case example of the beat-by-beat variability of the studied signals. a Example of the beat-by-beat variability of Non-corrected and Corrected PA Pressure and flow (PA Flow). Note how the synchronized changes on pressure and flow cycles are more evident when PA pressure signal is corrected (dashed rectangle). b Example of beat-by-beat measurement of reference stroke volume from the PA flow signal (SVref) and systolic area from non-corrected and corrected PA pressure. As shown in the dashed rectangle, the changes in SVref and Corrected PA Pressure SystAUC are in phase while the SVref and Non-corrected PA Pressure SystAUC are decoupled
