The Aerosol Inhalation Measurement System.
NIOSH 1990 Jan:149 pages
In an effort to measure the lung deposition of an aerosol as the aerosol is breathed into and out of the lungs of humans, an Aerosol Inhalation Measurement (AIM) System was designed. A 0.5 micrometer monodispersed corn-oil aerosol was used with the system since it is the the aerosol chosen by the U.S. Army respiratory fit test program. This system functioned over a range of breathing volumes and flow rates. A formal typed report was produced by a computer which showed the deposition value for individual breaths as well as the flow rate and volume breathed for each subject. Details were provided on the location and setup of the AIM system testing station, start up and calibration of the AIM system, the AIM system's computer programs, conducting total lung deposition tests with the AIM system, backup and storage of aerosol deposition test data, and evaluation of edited total aerosol lung deposition reports.
