Esophageal (a) and trans-diaphragmatic (b) swings. Individual and mean changes in esophageal and trans-diaphragmatic swings during the five weaning tests and 20 minutes after extubation. All the tests show that the weaning tests that best reproduce respiratory muscle work after extubation were pressure support ventilation (PSV) 0 cmH2O + positive end-expiratory pressure (PEEP) 0 cmH2O and the T piece, with no statistically significant difference between the two. *p < 0.001 when compared with after extubation.
