Delivery of inhaled medication in adults

Respirable dose — The most important characteristic of nebulizer performance is the respirable dose delivered to the patient. The respirable dose is a function of the mass output of the nebulizer and the size of the particles produced. Droplet size should be 2 to 5 µm for airway deposition and 1 to 2 µm or smaller for parenchymal deposition. ................
