Experimental tracings obtained during a breath from patient receiving PSV (pressure support 5 cmH2O). Time t0 is defined as where Pes starts to decrease; t1 is the onset of inspiratory flow; t2 is where Pes starts to increase; and t3 is the end of inspiration. Vab, abdominal volume; Vcw, chest wall volume; Vrc, a, volume of the abdominal rib cage; Vrc, p, volume of the pulmonary rib cage; Paw, airway pressure; Pdi, transdiaphragmatic pressure; Pes, oesophageal pressure; Pga, gastric pressure.
