Fig. 4

Individual patient changes in shunt, V/Q mismatch, and lung aeration. Changes from low to high PEEP in shunt and V/Q mismatch (top row) and lung aeration (bottom row). Beneficial and detrimental responses in shunt and V/Q mismatch to an increase in PEEP are marked by line styles, with solid and dashed lines signifying beneficial and detrimental responses, respectively. The combinations of symbols and line styles are unique per patient so that individual patients can be identified across all subplots
