In this study gas-exchange and respiratory mechanics variations to PEEP change will be correlated to CT lung morphological modifications assessed at different airway pressures (5, 15, 30 and 45 cmH2O).

Condition Intervention
ARDS: Acute Respiratory Distress Syndrome
Radiation: Chest computed tomography

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Primary Outcome Measures:
  • Computer Tomography (CT) scan lung recruitment and CT lung weight [ Time Frame: Study day (day 1) ] [ Designated as safety issue: No ]
    Aim of the study is to determine the relationship between the opening pressures (recruitment) and closing pressures (PEEP) in order to prevent the opening and closing of the lung parenchyma

Estimated Enrollment: 30
