Aggregate exhaled breath condensate oxides of nitrogen following VCBT. (a) EBC NO_𝑥 concentrations decreased 68% in control subjects after VCPT compared to baseline, pretreatment values (baseline = 115±32 μM versus post-VCPT = 37±17 μM; 𝑃<0.002). (b) CF subjects showed a significant decrease in EBC NO_𝑥 after vest percussion treatment (baseline = 224±55 μM versus post-vest = 52±11 μM; 𝑃<0.01).
