Airway and viscoelastic respiratory tissue mechanical parameters. Measurements obtained at positive end-expiratory pressures of 0, 3, and 6 cmH2O (PEEP0, PEEP3, and PEEP6, respectively) in control rats (closed circles, C, n = 14) and in rats in the type 1 diabetes (DM1, open squares, n = 13) and type 2 diabetes (DM2, open triangles, n = 14) groups. The symbols and error bars represent the mean and SD values, respectively. * p < 0.05 vs. PEEP0 within a group; † p < 0.05 vs. PEEP3; # p < 0.05 vs. C within a PEEP. Abbreviations: Raw, airway resistance; G, tissue damping (resistance); H, tissue elastance; η, tissue histeresivity (= G/H)
