Questions and Answers

What is the relationship between oropharyngeal deposition and the factors Da and Q?

  • 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)

    • How does inspiratory airflow affect aerosol deposition in the lungs?

  • 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

    • How does particle diameter influence agglomerate strength of the powder?

  • Particle diameter has no effect on agglomerate strength
  • Smaller particle diameter leads to weaker agglomerate strength
  • Greater particle diameter results in weaker agglomerate strength (correct)
  • Agglomerate strength increases with particle diameter
