Abstract
A system and method for simulating a human respiratory system to facilitate investigating the functioning of the respiratory system, such as the generation and effects of secondhand smoke. An aerosol generator, which may include an atomizer, is configured to generate an aerosol. A series of filter media includes, in order, an inhaling extrathoracic filter media, an inhaling tracheobronchial filter media, an alveolar filter media, an exhaling tracheobronchial filter media, and an exhaling extrathoracic filter media. Each filter media includes one or more layers of a material having a fiber diameter and a weight that simulate the corresponding region of the respiratory system. A conduit may be configured to define a path for the aerosol from the aerosol generator through the series of filter media. An instrument, such as a scanning mobility particle sizer, may be used to measure a property of a secondhand aerosol exiting the exhaling extrathoracic filter media.
