Nebula Spacer and Perfecta, breath enhanced nebulizers, deliver consistent particle size (<5µm) for targeted delivery to the bronchopulmonary apparatus. The applied technology ensures fast therapy and consistent deposition in the lungs. The nebulizers are fitted with two different volumetric masks. Both masks collect the drug during expiration phase, increasing the quantity of drug available for inspiration. This makes therapy more effective and reduce drug dispersal in the environment (reservoir effect).
