Acute respiratory distress syndrome (ARDS) is a condition occurring in severely ill patients. ARDS is characterized by inflammation in the lungs, and can occur in relation to e.g. severe trauma, sepsis, pneumonia, and pancreatitis. Common denominators are that inflammatory cascades in the body are triggered by microbial products or other damage associated products. Data from relevant animal models indicate a potential benefit of BioC in ARDS.
