Abstract:
High-frequency ventilation ( HFV) is theoretically an ideal ventilatory mode for lung pro-tection. It also delivers extremely small tidal volumes near to or less than the anatomically invalid cavity (about 2ml/kg) at very high respiratory frequencies (recognized ventilation frequency about 4 times more than the normal range) . Compared to the conventional mechanical ventilation,HFV makes use of lung-open mode,with low tidal volume, low airway pressure, low thoracic pressure and end-exhaling pressure effect, which can avoid recruitment/derecruitment of alveoli to reduce pressure injuries on lung tissue and airway. Nowadays,more and more critical care practitioners implement this ventilation mode. We reviewed the princi-ples,classification,parameters,and clinical indications of HFV in this article.
