Abstract

I’ high speed cinefluorographic record of changes of the COUGH is a singularly interesting tracheal shadow during a series of coughs. In the second respiratory movement in that the violent study, a series of tracings were made of the projections changes in intrapleural pressure and of several x-ray motion pictures of coughs obtained the generation of high rates of air flow during from patients having Lipiodol in the lung airways. the expiratory phase are accompanied by Measurements of ‘the changes in apparent tracheal and bronchial diameters were made at various points along marked changes in the lumens of the trachea the upper bronchial tree in an effort to reveal either the and bronchi of the lungs. These tracheobronpresence or absence of a wave-like motion along the chial changes have been observed both bronbronchial tree. In the third study, a section of human choscopically by Jackson (I) and radiographitrachea was suspended in a bottle which could be pressurized. The trachea was cannulated at one end tally by Di Rienzo (2) and must be responsible and communicated to the outside while the other end for the occurrence of the changes in resistance was plugged.
