Kinetic effects of carbon monoxide inhalation on tissue protection in ventilator-induced lung injury.

ABSTRACT: Mechanical ventilation causes ventilator-induced lung injury (VILI), and contributes to acute lung injury/acute respiratory distress syndrome (ALI/ARDS), a disease with high morbidity and mortality among critically ill patients. Carbon monoxide (CO) can confer lung protective effects during mechanical ventilation. This study investigates the time dependency of CO therapy with respect to lung protection in animals subjected to mechanical ventilation. For this purpose, mice were ventilated with a tidal volume of 12 ml/kg body weight for 6 h with air in the absence or presence of CO (250 parts per million). Histological analysis of lung tissue sections was used to determine alveolar wall thickening and the degree of lung damage by VILI score. Bronchoalveolar lavage fluid was analyzed for tota
