Representative flow resistance at different flow rates in three of the patient based models.

<p>Top row shows the contribution of each generation in the complete (parent) conducting airway models to the total airways resistance at the different tested flow rates. Three representative models are shown in the healthy (A), GINA 1–2 (C) and GINA 3–5 (F) groups. Bottom row shows the corresponding airway radii in each generation in each of the three representative models (Healthy (D), GINA1–2 (E), GINA 3–5 (F)). Error bars show standard deviation of the radii within a generation.</p>
