[Classification of x-ray findings and correlated oxygen tensions in "shock lung" (author's transl)]

The classification of the radiological features of the "shock lung" into stages represents a description of the characteristic radiological changes as they develop in the course of the lesion. As these changes do not succeed each other step by step but are superimposed their attribution to a particular stage therefore describes only the dominant substrate. Since the radiological changes and the corresponding oxygen tensions generally show satisfactory correlation a lack of correspondence during treatment may be an early sign of secondary disturbances or complications.
