Randomised controlled trials in preterm infants comparing HFOV to conventional ventilation have shown inconsistent results, with no overall differences in mortality but a small trend toward lower BPD incidence with HFOV. 1 Importantly, though, the benefit was greatest when HFOV was applied with an effective ‘high-lung volume strategy’, and least when HFOV was not (especially if lung protection was optimised during conventional ventilation). 1 A high-lung volume strategy prioritises achieving recruitment during HFOV.
