Aerodynamic Particle Size DistributionAerodynamic particle size distribution describes how the mass of an inhaled aerosol is spread across aerodynamic sizes, the property that governs where particles deposit in the airways.Pulmonary Drug DeliveryPulmonary drug delivery moves an active compound from an inhaler or nebulizer into the airways, where particle size, breathing pattern, and airway geometry decide how much reaches the lung.
