Die Differentialdiagnose der obstruktiven Lungenkrankheiten mittels Ganzkörperplethysmographie

Whole body plethysmography has turned out to be a suitable method for simple and speedy differentiation of the several forms of obstructive lung diseases. For this purpose pressure-flow-diagrams are compared with changes of intrathoracic gas volume as a function of time as well as with the influences of drugs on bronchial size. The practical value of this procedure is demonstrated in cases of simple bronchial asthma, asthmatic bronchitis with pulmonary emphysema, emphysema without bronchitis, and subtotal stenosis of one main bronchus caused carcinoma.
