Ml. Everard et al., COMPARISON OF NEBULIZED AEROSOL DEPOSITION IN THE LUNGS OF HEALTHY-ADULTS FOLLOWING ORAL AND NASAL INHALATION, Thorax, 48(10), 1993, pp. 1045-1046
A standard jet nebuliser was used to generate a radiolabelled aerosol
and the pattern of deposition within the airways of eight healthy adul
ts was studied with a gamma camera. Penetration of aerosol to the lung
was greatly reduced when breathing through the nose compared with mou
th breathing.
