Aerosol concentration of particles produced in the in vitro cough machine after delivery of isotonic saline or surfactant as a consequence of a burst of air over the simulated mucus. (A) The effect of saline delivery on density distribution of aerosol particles formed after exposure of mucus simulant surface to a burst of air in the in vitro cough machine. Four cases are shown: (i) mucus simulant (solid grey line), (ii) mucus simulant immediately after application of nebulized isotonic saline (dotted green line), (iii) mucus simulant 30 min after application of nebulized isotonic saline (dashed-dotted red line), and (iv) mucus simulant 60 min after application of nebulized isotonic saline (dashed blue line). (B) The effect of surfactant delivery on density distribution of aerosol particles formed after exposure of mucus simulant surface to a burst of air in the in vitro cough machine. Four cases are shown: (i) mucus simulant (solid grey line), (ii) mucus simulant immediately after application of nebulized isotonic saline (dotted green line), (iii) mucus simulant 30 min after application of nebulized isotonic saline (dashed-dotted red line), and (iv) mucus simulant 60 min after application of nebulized isotonic saline (dotted blue line).
