You’re probably aware that acute lung injury and acute respiratory distress syndrome (ALI/ARDS) carry a high mortality. But you may not know that high-frequency oscillatory ventilation (HFOV) can be used as a lung-protective strategy and rescue mode for patients who have this syndrome of acute, persistent lung inflammation with increased vascular permeability. To maintain effective oxygenation and ventilation, patients with ALI/ARDS require measures to protect the lungs, such as HFOV. Used for neonatal, pediatric, and adult forms of respiratory failure, HFOV differs from conventional mechanical ventilation by maintaining open lung volume through a constant mean airway pressure to achieve effective oxygenation, while oscillation removes CO2. HFOV has been studied across all patient ranges as a lung-protective strategy for ALI/ARDS refractory to conventional ventilation.
