Fig. 1 There were marked differences in PEEP and Pplat between the conventional mechanical ventilation group (conventional) and the minimal mechanical stress ventilation group (stress index).

Fig. 2 Elastance, which directly correlates with the degree of lung injury, was significantly higher in the conventional mechanical ventilation group (conventional) than in the minimal mechanical stress ventilation group (stress index; ***P <.0001 vs the conventional mechanical ventilation group).

Fig. 3 Pao2 of the transplanted lung was significantly higher in the minimal mechanical stress ventilation group (stress index) than in the conventional mechanical ventilation group (conventional; ***P <.0006 vs the conventional mechanical ventilation group). The difference between the Paco2 was not significantly different between groups (P =.1).

Fig. 4 The proinflammatory cytokines IL-6 and MIP-2 were significantly lower in the minimal mechanical stress ventilation group (stress index) than in the conventional mechanical ventilation group (conventional; *P <.05 and **P <.01 vs the conventional mechanical ventilation group). TNF-α was not significantly different between groups (P =.1).
