Experimental models of mechanical ventilation that limit phasic changes in lung volumes and prevent alveolar overdistension appear to be less damaging to the lung. High-frequency oscillatory ventilation using very small tidal volumes and relatively high end-expiratory lung volumes provides a safe and effective means of delivering mechanical ventilatory support with the prospect of reducing the development of ventilator-induced lung injury. Despite theoretical advantages and convincing laboratory data however the use of high-frequency oscillatory ventilation in the paediatric population has not yet been associated with significant improvements in clinically significant outcome measures. Introduction In this issue of Critical Care Slee-Wijffels and colleagues 1 report on the use of high-frequency oscillatory ventilation HFOV as a rescue therapy for children with severe respiratory failure in the paediatric intensive care unit. They describe 51 children with severe respiratory failure initially managed with conventional mechanical ventilation who required HFOV as rescue therapy. In this retrospective study the authors looked for differences between patients with a diagnosis of .
