Inhalation Exposure Facility

The objectives of the exposure core are to: expose animals or in vitro preparations to selected types and concentrations of air pollutants, accurately and in a carefully controlled manner; provide logistical and technical support in ensuring experimental regimens are implemented correctly; develop methods of inhalation exposure and atmosphere characterization; and develop methods of allergen characterization and assess allergic exposure response. (Pictured above: house dust mites).

Pulmonary Function Testing Laboratory

Under the expert guidance of Inhalation Exposure Core Manager Dr. Chris Royer, pulmonary function testing is available for measuring static mechanics of the respiratory system to allergen and other air pollutant inhalation. Also, dynamic mechanics measurements utilizing transfer impedance is available for non-invasive measuring of airway reactivity and other physiological responses of the respiratory system. Together, respiratory mechanical variables provide a translational structure-function map of the internal workings of the lung under the disease process being studied. These measures can be further integrated with other scientific areas expertise via collaboration with CNPRC Core and Affiliate Scientists.
