Abstract

The adult respiratory distress syndrome (ARDS) is classically regarded as a diffuse inflammatory lung disease. Recent computerized tomography (CT scan) studies, however, provided the evidence that in ARDS patients the lung lesions (densities at CT scan) are not homogeneously distributed throughout the lung parenchyma [1–3]. In most patients, though not in all of them, the lesions are preferentially located in the dependent regions of the lung, at least in supine position. These findings raise at least three types of questions:
  1. 1.

    is ARDS a really diffuse lung injury and, if so, why are lesions not homogeneously distributed?

     
  2. 2.

    what is the diagnostic and prognostic value of the assessment of respiratory mechanics in patients with ARDS if the lung is not homogeneously affected?

     
  3. 3.

    what is the impact of the different kinds of respiratory support on a dishomogeneous lung?
