What is Acute Respiratory Distress Syndrome?
Acute respiratory distress syndrome, commonly abbreviated ARDS, is a severe, life-threatening lung condition in which widespread inflammation causes fluid to leak into the air sacs of the lungs, severely impairing the lungs' ability to transfer oxygen into the bloodstream. It typically develops rapidly, within hours to days, following a serious illness or injury such as severe pneumonia, sepsis, major trauma, or aspiration of stomach contents, and represents the lungs' extreme inflammatory response to these triggers rather than a primary lung disease itself. Patients with ARDS often require mechanical ventilation in an intensive care unit to support breathing while the underlying cause is treated and the lungs are given time to heal. Despite modern treatment advances, ARDS carries a significant risk of death and long-term complications in survivors.

Causes of Acute Respiratory Distress Syndrome
ARDS develops when a triggering illness or injury causes widespread inflammation that damages the delicate barrier between the lungs' air sacs and blood vessels, allowing fluid to leak into the air spaces and impair oxygen exchange. Common triggers include severe pneumonia, sepsis from infection anywhere in the body, aspiration of vomit or stomach contents into the lungs, major trauma, and near-drowning. Certain risk factors, including chronic alcohol use, obesity, and pre-existing lung disease, increase the likelihood of developing ARDS when a triggering illness occurs.
Symptoms of Acute Respiratory Distress Syndrome
severe shortness of breath, rapid, labored breathing, low blood oxygen levels despite supplemental oxygen, bluish discoloration of lips or fingertips, rapid heart rate, confusion or fatigue from low oxygen, excessive coughing, chest discomfort
Treatment & Types of Acute Respiratory Distress Syndrome in Karnataka
Treatment centers on supportive care in an intensive care unit, most critically mechanical ventilation using carefully calibrated low-pressure, protective ventilation strategies designed to support oxygenation while minimizing further lung injury. Positioning patients on their stomach, known as prone positioning, has been shown to significantly improve oxygenation in moderate to severe cases. Treating the underlying trigger, such as administering antibiotics for infection or source control for sepsis, alongside careful fluid management, is essential alongside respiratory support, and extracorporeal membrane oxygenation may be used in the most severe cases when ventilation alone is insufficient.
ARDS is classified by severity using the Berlin definition, based on how poorly oxygen transfers into the blood while a patient is on a ventilator: mild, moderate, and severe ARDS, determined by the ratio of blood oxygen level to the amount of oxygen being delivered. This grading helps guide ventilator strategy and predicts likely outcomes.

Frequently Asked Questions
Is ARDS the same as pneumonia?
No, ARDS is the lungs' severe, widespread inflammatory response that can be triggered by pneumonia or other serious illnesses like sepsis, rather than being an infection itself.
Can someone survive ARDS?
Yes, though it is a serious condition; survival depends heavily on severity and how quickly ventilator support and treatment of the underlying trigger are started.
Will lung damage from ARDS be permanent?
Some survivors have lasting reduced lung capacity, but many recover a meaningful amount of lung function over the following months.
Why do doctors position patients on their stomach?
Prone positioning improves how air and blood flow are matched in the lungs, meaningfully improving oxygen levels in moderate to severe cases.
What most commonly triggers ARDS?
Severe pneumonia and sepsis from infection elsewhere in the body are the two leading triggers.
