Oxygen Delivery in the Adult Intensive Care Unit with a Focus on Hyperoxic Acute Lung Injury Pathogenesis and Clinical Manifestations.
High oxygen damages human lung, called hyperoxic acute lung injury (HALI). HALI pathogenesis involves formation of reactive oxygen species (ROS) which overwhelm antioxidant mechanisms and lead to alveolar epithelial and endothelial cell death and interstitial inflammation. Resultant alveolar flooding causes ventilation...
