Chronic Obstructive Pulmonary Disease (COPD) is a preventable and treatable disease with some significant extrapulmonary effects that may contribute to the severity in individual patients. Its pulmonary component is characterized by airflow limitation that is not fully reversible . The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lung to noxious particles or gases.
Clinical Disorders Commonly Associated with ARDS Post-cardiopulmonary bypass Pancreatitis Toxic inhalation injury Drug overdose Near-drowning Multiple transfusions Pulmonary contusion Severe trauma Aspiration of gastric contents Sepsis Pneumonia Indirect Lung Injury Direct Lung Injury
