Abstract:
High Frequency Jet Ventilation (HFJV) is a form of mechanical ventilation that delivers tiny gas volumes (less than the anatomical dead space) at rapid rates. It has been used extensively in the United States and to a lesser extent in Australia to treat neonatal respiratory failure as an alternative to conventional (tidal) mechanical ventilation and has been shown to be especially effective in the treatment of intractable air leaks, such as pulmonary interstitial emphysema, airway disruptions, and pneumothorax. This presentation will review the salient features of HFJV including differences among rapid rate conventional ventilation and high frequency oscillatory ventilation in gas delivery, mechanisms of gas exchange and how they impact oxygenation and ventilation, complications, disease-specific strategies and clinical management.
