Fig. 3

Driving pressure (ΔP, in cmH2O) vs. tidal volume (VT, in mL/kg ideal body weight) during all periods of stable compliance (661 periods from 60 patients), colored according to the range of respiratory system compliance (Crs, mL/cmH2O). Dotted vertical and horizontal lines indicate thresholds of ΔP ≥ 15 cmH2O and VT ≥ 8 mL/kg, respectively, and solid black lines indicate the correlation lines for each range of compliance. In the upper right quarter (values ΔP ≥ 15 cmH2O and VT ≥ 8 mL/kg), there are 11 points (10 points with compliance 21–30 mL/cmH2O and one point with compliance of 31 mL/cmH2O), pertaining to four patients
