  1. Values are mean ± SEM.
  2. For ∆Pes, Raw and CO2 response statistical differences were determined by a one-way analysis of variance. For room air ventilation and CO2 ventilation, statistical differences were determined by a two-way ANOVA followed by a post-hoc Student–Newman–Keuls test.
  3. ∆Pes inspiratory swings in esophageal pressure, raw airway resistance, AO obstructive, mAO mild obstruction, OR obstruction removal.
  4. *p < 0.01—C vs. AO, mAO or.
  5. +p < 0.05, mAO vs. AO.
