From: The increase of vasomotor tone avoids the ability of the dynamic preload indicators to estimate fluid responsiveness

Figure 3

The four-quadrant plots and polar plots to examine the trending abilities of PPV against SVV under normal vasomotor tone (PHE-) and under increase vasomotor tone (PHE+). Half-circle polar plots are shown with data transformed to positive directional data only. We applied an exclusion zone when the percentage of change of data was below 15% (0.5). SVV: stroke volume variation, PPV: pulse pressure variation.
