BRONCHOSCOPICAL OBSERVATIONS AFTER INHALATION OF DYES UNDER NORMAL AND MORBID CONDITIONS OF THE RESPIRATORY TRACT
Abstract
The introduction gives a brief survey of the methods hitherto used in order to investigate the penetration of the respiratory tract of animals and man by inhaled aerosols. A report is then given on the methodology of the author's own dye-inhalation experiments on man. A small number of persons in the experiment inhaled Evans Blue with a bronchoscope inserted in the upper trachea or in the lower interbronchial area. Most of them inhaled the dye before bronchoscopy. In demonstrating the results in the normal respiratory tract and in case of various pathological conditions in the bronchial system and in the pulmonary parenchyma, the author in each instance shows first of all a photograph giving a general view of the lungs, often supplemented by photographs of the layers, and then the bronchoscopically obtained color photograph with the dye precipitation that is present, usually supplemented by bronchograms.
