Tracheobronchial histopathology associated with high-frequency jet ventilation.


We compared the tracheobronchial histopathology seen after conventional mechanical ventilation (CMV) and high-frequency jet ventilation (HFJV) in 44 adult cats. Two different HFJV humidity systems were examined: one used entrained mist alone, and the other infused 3 ml/kg X h of 0.45% NaCl directly into the jet stream. HFJV produced more tracheal damage… (More)
