Figure 4From: Study of multiparameter respiratory pattern complexity in surgical critically ill patients during weaning trialsPhase space of mean inspiratory flow in a weaning failure patient. Red dots represent data during high PS ventilation, whereas blue dots represent data during the performance of a SBT. Scattering of data seems reduced, compared with findings in figure 3, reflecting decreased variability of the measured parameter. Moreover, flow values are positioned in different parts of the space.Back to article page
