High-frequency oscillatory ventilation in adults: handle with care
In the previous issue of Critical Care, Gu and colleagues reported the results of a systematic review and meta-analysis of randomized trials comparing high-frequency oscillatory ventilation (HFOV) with conventional ventilation in adults with acute respiratory distress syndrome (ARDS). In contrast to findings of prior meta-analyses, their main finding was that, despite reducing risks of oxygenat...
متن کاملhigh frequency oscillatory ventilation in severe respiratory failure
despite improvement of mechanical ventilation devices for infants, lung injury still causes morbidity and mortality in many cases. to determine the effect of high frequency oscillatory ventilation (hfov) in infants with severe respiratory failure, 10 neonates were evaluated prospectively. mean gestational age of these patients was 35 weeks and alveolar-arterial oxygen gradient (a-ado2) and the ...
متن کاملUse of high-frequency jet ventilation in neonates with hypoxemia refractory to high-frequency oscillatory ventilation.
OBJECTIVE To describe the response to high-frequency jet ventilation in infants with hypoxemic respiratory failure unresponsive to high-frequency oscillatory ventilation. METHODS This was a retrospective analysis of chart records on demographics, ventilator settings, blood gas analysis and calculated oxygenation index prior to and during the first 7 days of high-frequency jet ventilation in t...

HFOV is a mode of ventilation that can achieve oxygenation and ventilation while maintaining maximal lung recruitment on the deflation limb of its pressure-volume curve. The primary theoretical advantages of HFOV over CMV in the management of acute lung injury are that HFOV allows adequate alveolar ventilation with minimal peak-trough pressure changes, provides lung recruitment, and avoids end-...

We thought it was impossible. Physiological principles maintained that ventilation at tidal volumes less than the anatomical deadspace should be ineffective (i.e., inspired air not reaching the alveolae). Data from a 1980 study dispelled that myth, showing unequivocally that ventilation with tidal volumes as small as 20 to 30 ml in dogs, a mere fraction of the anatomical deadspace, could mainta...
