VTd - delivery tidal volume; VTp - predicted tidal volume; VT - tidal volume; PBW - predicted body weight; ARDS - acute respiratory distress syndrome. “p” represents the statistical significance between delivered and predicted volumes. The delivered volume is represented also related to the predicted body weight. Values are the means and standard error.
