Relationships between tidal volume (Vt) and driving pressure (∆P), i.e. respiratory system compliance (Crs), measured in the five pressure support (PS) steps. Respective PS values in cmH2O are reported above each point as mean ± SD rounded to the unit. The regression line of Crs measurements is represented in dotted. Crs did not change among steps (P = 0.119) irrespectively of the level of assistance applied in the PS range tested. Data are presented as mean ± SD
