Anesthetized rats were instilled intratracheally with HCl (0.1 N, 2 mL/kg) and then randomly divided into three mechanical ventilation settings: HFOV (an oscillatory frequency of 15 Hz, mean airway pressure (MAP) of 9 cmH(2)O), CMV at tidal volume of 12 and 6 mL/kg for 5 h. After HCl instillation, HFOV significantly attenuated the increases in neutrophil infiltration and TNF-alpha concentration in bronchoalveolar lavage fluid compared with the CMV groups. During HFOV, there was an inhibition of an increase in TNF-alpha mRNA expression and a decrease in SP-A mRNA expression induced by acid instillation. This animal study demonstrates that HFOV is a suitable form of mechanical ventilation to prevent inflammatory responses in acid-induced lung injury., Article, INFLAMMATION RESEARCH. 59(11):931-937 (2010)}, pages = {931--937}, title = {Comparison of acid-induced inflammatory responses in the rat lung during high frequency oscillatory and conventional mechanical ventilation}, volume = {59}, year = {2010} }
