An inflammatory infection that occurs in the lung.

ARDS (Acute Respiratory Distress Syndrome) is breathing failure that can occur in critically ill persons with underlying illnesses. It is not a specific disease. Instead, it is a life-threatening condition that occurs when there is severe fluid buildup in both lungs. The fluid buildup prevents the lungs from working properly—that is, allowing the transfer of oxygen from air into the body and carbon dioxide out of the body into the air.
