Table 3 Summary of changes in SpO2/FiO2, pCO2, pH, ΔPproximal and tidal volume (Vt), assessed just before the lung volume optimization maneuver (LVOM) when the patients were on conventional mechanical ventilation (CMV) [T0], at the last applied CDP during the incremental (T1) and decremental phase (T2), and one hour after the LVOM [T3]
