Aerodynamic Particle Size DistributionAerodynamic particle size distribution shows how the mass of an inhaled aerosol is distributed across aerodynamic sizes, which helps determine where particles are likely to deposit in the airways.Pulmonary Drug DeliveryPulmonary drug delivery carries an active compound from an inhaler or nebulizer into the airways. Particle size, breathing pattern, and airway geometry determine how much of the dose reaches the lung.
