High-frequency oscillatory ventilation seems theoretically ideal for the treatment of patients with ARDS, allowing adequate oxygenation and ventilation to be maintained without causing further damage to the already injured lung. High-frequency oscillating ventilation also seems a sound strategy for improving oxygenation in patients who are no longer responding to conventional mechanical ventilation. Currently, HFOV should be used in the adult ICU as one of many ancillary therapies available for the treatment of extremely ill, hypoxemic patients with ARDS. Future research may define the role of HFOV as a more routine strategy for preventing VALI in this patient population.
