ABSTRACT:
A subject rebreathes an inert aerosol from a closed system and, during each of a plurality of breaths, the aerosol concentration in the closed system is determined and compared to determine differences with a predetermined concentration value. Identified differences indicating enhanced aerosol deposition signify airway narrowing and/or an increase in accumulated airway secretions.
