This study determined the effect of nostril dimensions, nasal passage geometry, and nasal resistance (R) on particle deposition efficiency (PDE) in 40 healthy, nonsmoking adults (24 male, 16 female) at a constant flow rate. An aerodynamic particle sizer measured the diameter and concentration of a polydispersed (1-10-μm diameter) aerosol drawn unidirectionally into the nose and out the mouth.
