From: How we approach titrating PEEP in patients with acute hypoxemic failure
CT scan of two ARDS patients with different potential for lung recruitment. This figure shows images of two different patients, both fulfilling the criteria for ARDS. The CT scan in the left panel is characterized by extensive ground glass appearances, but limited consolidations, whereas the patient in the right panel has extensive gravity dependent consolidations. Obviously, the potential for lung recruitment with PEEP is much higher in the patients in the right panel
