Measurement of total lung aerosol deposition as an index of lung abnormality
Journal of Applied Physiology, 1988Total aerosol deposition in the lung was measured in 100 subjects with various lung conditions. The subjects consisted of 40 normals (N), 15 asymptomatic smokers (S), 10 smokers with small airway disease (SAD), 20 with chronic simple bronchitis (SB), and 15 with chronic obstructive bronchitis (COPD), and a relationship of total aerosol deposition to ...

Fluid Dynamics Modeling of Particulate Deposition in the Lungs
The International Journal of Artificial Organs, 2005Detailed knowledge of the transport of air and particles in the human lungs is needed for two reasons: the selection of the right dosage of aerosol drugs used in respiratory therapy and the analysis of the maximum allowable concentration for particulate in air.

Deposition of fibers in the rat lung
Journal of Aerosol Science, 1989Abstract The deposition and clearance of inhaled particles in the lungs of different mammals have been the subject of many investigations. Any analysis on the particle removal from the lung requires a knowledge of the initial deposition pattern of inhaled particles at different sites.

Aerosol Deposition in the Lungs of Space Travellers
Nature, 1966THE deposition of aerosols in the lungs of man during breathing constitutes an important mechanism for the entry of toxins or pathogenic organisms to the body. The respiratory tract is protected by an efficient ciliary mechanism for the rapid removal of particles deposited in the upper airways.

Inertial deposition of particles in the lung
Journal of Aerosol Science, 1973Abstract Initial results on the inertial deposition of aerosol particles in simple bends are reported. Reference to the literature has revealed an error in the interpretation of previous experiments. This has led to incorrect estimates of particle deposition in the human lung. The implications of this error are discussed.

Lung deposition in freshly excised human lungs.
Inhaled particles, 1977An artificial chest wall was constructed which was large enough to hold a whole excised human lung. this device was connected to a modified Harvard Respirator which was capable of being programmed to produce any reasonable respiration rate. Freshly excised lungs free of any disease and cuts wer placed in the chest wall and challenged with both ...
