Allergen Dispersion System Development in an Exposure Room

Patients can be exposed to airborne allergens in specially designed and controlled rooms for clinical studies. This research aims at improving the spatial homogeneity and temporal stability of airborne pollen concentration in a new exposure room over a period from 2 to 6 hours. Initially, the flow dynamics and particle dispersion will be also investigated using CFD (Computational Fluid Dynamics) numerical techniques. Pollen (ragweed, birch, and grass) will be characterized experimentally using SEM (Scanning Electron Microscope) and particle settling-velocity measurements. Pollen size distribution and concentration in time and space will be measured when the new testing room is completed. The results will be used to develop better monitoring and controlling of allergen levels, so that consistent and stable concentrations may be maintained within a specified range during tests. This will allow better controlled exposure during allergy studies.
