Dry Powder and Budesonide Inhalation Suspension Deposition Rates in Asthmatic Airway-Obstruction Regions

Figure 3

The sizes of the particles, deposited in the airway obstruction regions, generated by the (a) Turbuhaler or Symbicort (DPI), (b) NE-U22 (mesh nebulizer), and (c) NE-C28 (jet nebulizer). All particle sizes were measured using the Cascade Impactor. This connective method and air flow speed are basic style of Marple 8 stage cascade impactor.
