Efficacy of inhaled nitric oxide in oleic acid-induced acute lung injury

Abstract

The effect of inhaled nitric oxide, restricted to relieving pulmonary vasoconstriction in this model of lung injury, may have limited benefit in improving pulmonary gas exchange when diffusion is impaired by severe lung injury and inflammatory thickening of the alveolar-capillary barrier. Nitric oxide inhalation may have better results when used at an earlier, less severe stage of acute lung injury.
