a Patient with AE-IPF during assisted spontaneous breathing with end-expiratory positive pressure of 4 cmH2O and pressure support of 10 cmH2O. Note ΔPes of 30 cmH2O due to respiratory drive hyperactivity. b Thorax CT scan performed on same patient as (a), showing anterior left pneumothorax probably due to high transpulmonary pressure. Note homogeneous increase of parenchymal density. c Patient with AE-IPF during assisted spontaneous breathing with end-expiratory positive pressure of 4 cmH2O and pressure support of 10 cmH2O. Note ΔPes of 5 cmH2O due to normal activation of respiratory drive. d Thorax CT scan performed on same patient as (b) showing nonhomogeneous opacities in lung parenchyma. Pes esophageal pressure.
