FIGURE 4.
Peak inspiratory pressure (PIP), airway and viscoelastic respiratory tissue mechanical parameters obtained during volume-controlled ventilation with physiological parameters (NV) and injurious ventilation in control rats (CTRL), in rats with metformin-treated type 2 diabetes (MET), and in rats with untreated type 2 diabetes (T2DM). (A) : Absolute changes in mean values ±standard deviation (SD). (B) : Changes after 4 h of injurious ventilation values relative to the values obtained at 0 h. *p < 0.05 vs. 0 h; #p < 0.05 vs. 2 h; $p < 0.05 vs. CTRL; §p < 0.05 vs. MET. Abbreviations: PIP, Peak inspiratory pressure; Raw, airway resistance; G, tissue damping (resistance); H, tissue elastance.
