Difference in percentage change in respiratory mechanics with MDI versus SVN
| Time (h) | Crs (SEM) | p | Rrs (SEM) | p |
|---|---|---|---|---|
| Statistically significant (p<0.05) differences in percentage changes in respiratory mechanics with MDI versus SVN at each sample time determined by Wilcoxon signed rank test. Values represent means (SEM). | ||||
| Crs, respiratory system compliance (ml/cm H2O); Rrs, respiratory system resistance (cm H2O/ml/sec); MDI, metered dose inhaler plus spacer; SVN, small volume nebuliser. | ||||
