Web19 mei 2024 · The lower frequency leads to a longer absolute I.T. which results in a larger tidal volume of gas displaced towards the infant. This increased TV leads to increased alveolar ventilation (on HFOV, Ve ≈ (TV) 2 f). Web27 mrt. 2024 · Recently, Wong et al. reported increased 28-day mortality among 328 children with pediatric acute respiratory distress syndrome (PARDS) managed with high-frequency oscillatory ventilation (HFOV) [ 1 ]. This study is an excellent example of gaining a better understanding of pediatric critical care through multicenter collaboration.
