Aerosol Deposition Quiz

Oropharyngeal deposition is inversely related to Da and directly related to Q
Oropharyngeal deposition is independent of both Da and Q
Oropharyngeal deposition is solely determined by the factor Q
Oropharyngeal deposition follows the relationship Da2Q, increasing both factors increases oropharyngeal deposition (correct)

Lower inspiratory airflow decreases particle dispersal, increasing Da and requiring a balance of Q
Higher inspiratory airflow provides energy for particle dispersal, decreasing Da and requiring a balance of Q (correct)
Inspiratory airflow has no significant impact on aerosol deposition in the lungs
Higher inspiratory airflow increases Da and reduces Q, leading to greater lung deposition
