Figure 2

Representative strip-chart recorder tracing describing the methods used for measuring tidal swings in the pleural pressure (Ppl) and transdiaphragmatic pressure (Pdi) tracings. The pressure–time integrals of the diaphragm (∫Ppldt) and pleural pressure (∫Pdidt) were computer-calculated as the area of the pressure tracing defined by the inspiratory portion of the airflow tracing. EXP, expiratory; INSP, inspiratory.
