Exposure to Air Pollution Exacerbates Inflammation in Rats with Preexisting COPD

Figure 4

The effect of PM2.5 on pulmonary function in rats with COPD. (a) The change of noninvasive lung function parameters TV, PEF, and EF50 of rats in each group from week 0 to week 16, as well as at week 16. (b) The change of invasive lung function parameters FVC, FEV0.3, and FEV0.3/FVC of rats in each group at week 16. TV: tidal volume; PEF: peak expiratory flow; EF50: expiratory flow 50%; FVC: forced vital capacity; FEV0.3: forced expiratory volume at 0.3 s; FEV0.3/FVC: forced expiratory volume at 0.3 s/forced vital capacity. The data are expressed as the (). , .
