Abstract: | The removal of air-borne particles in the respiratory tract is treated to enable regional deposition to be inferred from measurement
of expired aerosol as well as predicted from theory of the primary removal processes. The analysis uses the analogy of a continuous
tubular filter-bed and includes consideration of respiratory pauses and the mechanical mixing of gas flow. Derived equations
relate regional deposition, distribution of aerosol in the expired air, and efficiency of removal at different depths in the
respiratory tract. |
