1 At time zero, a water column of 10 cm H2O was poured above the tested endotracheal tube (ETT) cuffs.
At time zero, a water column of 10 cm H2O was poured above the tested endotracheal tube (ETT) cuffs. The graphics represent the mean ± SD of the residual vertical height of the water column (cm) at incremental times with PEEP 0, 5, 10, and 15 cm H2O.
