Open Access Abstract Introduction Acute lung injury ALI can result from various insults to the pulmonary tissue. Experimental and clinical data suggest that spontaneous breathing SB during pressure-controlled ventilation PCV in ALI results in better lung aeration and improved oxygenation. Our objective was to evaluate whether the addition of SB has different effects in two different models of ALI. Methods Forty-four pigs were randomly assigned to ALI resulting either from hydrochloric acid aspiration HCl-ALI or from increased intra-abdominal pressure plus intravenous oleic acid injections OA-ALI and were ventilated in PCV mode either with SB PCV SB or without SB PCV - SB . Cardiorespiratory variables were measured at baseline .
