Table 5.

Regional DF values (given in %) with condensational size change for the cannula, nostrils, and nasal cavity of each model. Also shown is the DE of the total nose-throat region including the nostrils, nasal cavity, and nasopharynx. The particles considered include 0.9 μm and 1.5 μm solid formulations of 50:50 AS:NaCl, and a 5 μm droplet of 0.1% AS:0.1% NaCl. The mean, 95% CI, and CV for the total nasal DE of each initial particle size are also included.
