Tidal airway P/V curves (red), chest wall P/V curves (green), and lung P/V curves (blue) in model with normal (left panel) and stiff chest wall (right panel). End-expiratory P/V points are marked with filled circles. Blue dashed line: best fit lung P/V curve transpositioned to start at zero pressure. Note that the best fit lung P/V curve is passing through the end-expiratory airway P/V points and that the end-expiratory pleural pressure remain unchanged and negative when increasing PEEP, indicating an negligible end-expiratory chest wall elastance
