Abstract
Tracheobronchial clearance has been studied by means of human inhalation of a test aerosol of 6-micrometer Teflon parti- cles (density 2 gm/ml) tagged with technetium Tc 99m and subsequent external measurement of the radioactivity in the lungs for two hours. Clearance was studied twice in eight subjects: (a) when they were inhaling carbon dust and (b) when they were not Clearance was on the average significantly faster in the former case. Since the subjects inhaled carbon dust after inhaling the test aerosol, the faster clearance indicates a faster mucociliary transport.Keywords
