Evaluation of the Lung Recruitment and End-expiratory Lung Collapse in Acute Respiratory Distress Syndrome (ARDS)

Evaluation of the Lung Recruitment and End-expiratory Lung Collapse in Patients With Acute Respiratory Distress Syndrome

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).

Inclusion Criteria:

• Clinical diagnosis of acute lung injury/ acute respiratory distress syndrome
• Mechanical ventilation

Exclusion Criteria:

• Clinical diagnosis of chronic obstructive pulmonary disease
• Clinical diagnosis of pneumothorax
• Haemodynamic instability
