Best fit lung P/V curves from PEEP steps of 4, 8, and 12 cmH2O in isolated lung (red), normal chest wall stiffness (long dash, black), and extra stiff chest wall (short dash, black). Filled circles indicate end-expiratory P/V points and open circles end-inspiratory P/V points of isolated lung. Note that end-expiratory and end-inspiratory transpulmonary P/V points are aligned on a common transpulmonary P/V curve, and consequently, the transpulmonary pressure at a certain lung volume is independent of whether this specific lung volume is a result of a tidal inflation or PEEP inflation
