Fig. 4

Changes in respiratory muscle activity to increase in pressure support. Representative waveforms of flow (in l/s), airway (Paw), esophageal (Pes), transdiaphragmatic (Pdi), and gastric (Pga) pressures (in cmH2O), during an end-inspiratory occlusion, from two patients (upper and lower panel), ventilated with low (left) and higher levels of PS (right panel). The blue arrows indicate the estimated magnitude of expiratory muscle activity
