From: Novel method of transpulmonary pressure measurement with an air-filled esophageal catheter
Representative simultaneous esophageal and pleural pressures waveforms. Simultaneous esophageal and pleural pressure traces are recorded from air-filled esophageal catheter (Pes_C), esophageal balloon catheter (Pes_B) and pleural catheter (Ppl), together with airway pressure (Paw) and Flow traces in a patient in assisted mode. Two successive end-expiratory occlusion tests induce increased esophageal, pleural and airway pressure deflections and are delimited by vertical lines
