Alterations in Ventilation-perfusion Relationships in the Lung after Breathing Inert Dust or Bronchoconstrictor Aerosols and after Short Periods of Voluntary Hyperventilation.


The increase in airway resistance that follows the breathing of fine inert dust was first demonstrated by DuBois and Dautrebande (1), who also showed that an aerosol of carbachol had the same effect. The compliance of the lungs was reduced, which led these authors to conclude that the increased airway resistance was unevenly distributed. Constantine and… (More)
