title: [Radiological changes of the lungs induced by inhalation of irritating gases (author's transl)].
abstract: The radiological changes and clinical symptoms induced by in 109 persons by inhalation of irritant gases are described. Seven persons developed pulmonary oedema, abnormal radiological manifestations were observed in 19 while 81 persons there were no detectable radiological changes. Toxic pulmonary oedema is frequently detected earlier by roentgenologic means than clinically. The length of the radiological latent period depends not only on the concentration of the irritant but also on the type of the gaseous substance. The first roentgenologic signs of toxic pulmonary oedema are broadening and blurring of the outline of the hilar vessels. The pulmonary changes are characterized initially by disseminated small to medium sized shadows in the central portion and base of the lungs; later they tend to spread and merge.
