Adult respiratory distress syndrome (ARDS) is a life-threatening lung condition. It is a form of lung failure that can occur in very ill or severely injured people. It is not a specific disease. It starts with swelling of tissue in the lungs and build up of fluid in the tiny air sacs that transfer oxygen to the bloodstream. This leads to dangerously low blood oxygen levels.
ARDS is similar to infant respiratory distress syndrome, but the causes and treatments are different. ARDS can develop in anyone over the age of one year old.
