Adult Respiratory Distress Syndrome

(ARDS; Acute Respiratory Distress Syndrome; Non-cardiogenic Pulmonary Edema)

Definition

Adult respiratory distress syndrome (ARDS) is a form of lung failure. It is a life-threatening lung condition. ARDS can occur in very ill or severely injured people. It is not a specific disease.ARDS starts with the tiny blood vessels in the lungs. These vessels leak fluid into the lung sacs. The fluid decreases the ability of the lungs to move oxygen into the body.ARDS can develop in anyone over the age of one year old.
