This is a prospective single-center cohort trial to compare regional bronchial recruitment, bronchial distention and alveolar recruitment in 6 patients with acute respiratory distress syndrome (ARDS). The investigators used CT scan images as the imaging modality, and the subjects were scanned on end-expiratory lung volume with different positive end-expiratory pressures. Those images were post-processed to evaluate the airways.

Correlation between parenchymal recruitment and bronchial recruitment
Correlation between parenchymal recruitment (in milliliter) and bronchial (in milliliter) recruitment for each type of ARDS (focal versus diffuse)
Time frame: Through study completion, within 24 hours after inclusion
