Fig. 1From: PEEP-induced alveolar recruitment in patients with COVID-19 pneumonia: take the right time!Computed tomography at two PEEP levels in two recruiters (top panels) and two non-recruiters (bottom panels). Recruitment is computed as the difference between PEEP 8 and 16 cmH2O in non-aerated tissue, expressed as percentage of the total lung weight. ΔVgas is the increase of lung gas volume from 8 to 16 cmH2O PEEPBack to article page
