Fig. 2

Frequency dependences of the Rrs (a) and Xrs (b) of the healthy subjects (n = 10) are shown. Values during inspiratory and expiratory phases are mean ± SD (cmH2O/L/s). Averages of Rrs and Xrs during a whole breath are also shown (dashed lines). *Significant difference (P < 0.05) between inspiratory and expiratory phases by two-way repeated measure ANOVA, followed by Bonferroni test for post hoc analysis
