Fig. 3

Correlation of lung aeration and shunt and V/Q mismatch. Scatterplots of changes in gas exchange parameters and CT scan lung aeration with increases in PEEP (values at high minus low PEEP) and linear regression lines (solid lines). a Changes in ΔA-cPCO2 versus changes in hyperinflated lung regions. b Changes in ΔA-cPO2 versus changes in poorly aerated lung regions. c Changes in shunt versus changes in non-aerated lung regions. d Changes in shunt versus changes in normally aerated lung regions
