  1. After the completion of surfactant depletion, the rabbits were ventilated by conventional mechanical ventilation (CMV) or by high-frequency oscillatory ventilation (HFO) for 4 h at the same mean airway pressure. LL = lung lavage. *P < 0.05 vs the value before the first LL; †P < 0.05 vs the value before and 15 min after the first LL; ‡P < 0.05 vs the values of HFO at 4 h after the first LL.
