Work of breathing (WOB) in J/L (a) and in J/minute (b). Individual and mean changes in the WOB during the five weaning tests and 20 minutes after extubation. All the tests show that the weaning tests that best reproduced respiratory muscle work after extubation were pressure support ventilation (PSV) 0 cmH2O 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
