Large airway resistance (Rn) (Panels a, b & c ) and tissue elastance (h) (Panels d, e & f ) in Brown Norway rats exposed to silver nanoparticles at PEEP 3, 6 and 9 cm H2O, at 1 and 7 days post inhalation as a function of lung deposited doses of silver. Data shown as mean ± SD, n = 6 rats per group. *P < 0.05 and **P < 0.01 versus the air only control (0) within each time-point
