ARDS is caused due to fluid leakage from the small lung vessels into the lung air sacs (alveoli). It causes difficulty in breathing and severe falls in oxygen in the body.
ARDS commonly occur due to lung injuries:
- Major trauma and burn injuries may directly damage the lungs and inflame them
- Head, chest, or other major injuries
- Sepsis (a life-threatening condition when chemicals are released into the bloodstream by your immune system to fight off infection)
- Pneumonitis (swelling of the air sacs as a reaction to several agents)
- Injury to the head, chest, or other organs of your body
- Massive blood transfusions
- Pancreatitis (severe inflammation of the pancreas)
- Near drowning
- Aspiration (breathing food into your lungs)
- Viral infections such as coronavirus disease 2019 (COVID-19), herpes simplex virus (HSV), and cytomegalovirus (CMV)
- Breathing in harmful things, chemical fumes, and smoke
- Drug overdoses such as cocaine and opioid
- Medication side effect
Your risk of ARDS may increase if you have
- Advanced age.
- A history of tobacco use.
- A history of alcohol use.
- Chronic lung disease and are using oxygen.
- Undergone high-risk surgery recently.
- Undergone chemotherapy.
- Excessive weight.
What are the chances of surviving ARDS?
Acute respiratory distress syndrome (ARDS) is dangerous lung damage that allows fluid to leak into the lung air sacs (alveoli). This hampers the oxygen transfer process at the lung level. The body organs such as the kidney and brain stop working. The person will experience severe breathing difficulties, which will require immediate artificial oxygen support to help them breathe. It is an emergency condition and requires immediate medical attention.
It commonly occurs in critically ill people who are hospitalized for an injury or severe illnesses such as
It can worsen quickly, usually developing within a few hours to a few days of the injury or infection. Chances of survival in people who develop ARDS depend on the age and severity of their co-existing medical issues. However, with time, treatments are improving, and more people survive ARDS now than they did in the past. Although many survive, there may be some lung damage in many individuals.
- Fast diagnosis and treatment in ARDS are very important for the survival of patients.
What are the symptoms of ARDS?
If you have acute respiratory distress syndrome (ARDS), your symptom may vary in intensity, depending on its cause and severity, as well as the presence of an underlying heart or lung disease.
What are the complications?
- Blood clots
- Pneumothorax (collapsed lung)
- Infections due to tubes inserted into your windpipe
- Pulmonary fibrosis (scarring and thickening of the tissue between the air sacs that stiffen your lungs, making it even more difficult for oxygen)
- Breathing problems
- Problems with memory and thinking clearly
- Tiredness and muscle weakness

COPD (Chronic Obstructive Pulmonary Disease)COPD or chronic obstructive pulmonary disease is a lung condition caused by smoking tobacco, exposure to secondhand smoke, and/or air pollutants. Conditions that accompany COPD include chronic bronchitis, chronic cough, and emphysema.
Symptoms of COPD include shortness of breath, wheezing, and chronic cough. Treatment of COPD includes GOLD guidelines, smoking cessation, medications, and surgery. The life expectancy of a person with COPD depends on the stage of the disease.
How Serious Is a Blood Clot in the Lungs?A blood clot is a solid or semisolid clump of blood. When the tissues of our body are injured, excessive blood loss is prevented by the clotting of blood. When a blood clot occurs inside the blood vessels it may lead to serious medical conditions. When a blood clot occurs inside the arteries to the lungs, the condition is called pulmonary embolism (PE).
Is Sepsis Contagious?Sepsis is a potentially life-threatening infection that may be caused by bacteria, fungi, viruses, or parasites. Sepsis spreads within the body from the infection site. Treatment of sepsis typically involves the administration of intravenous medications.

Lung Anatomy DiagramThe lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
Lungs PictureThe lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). See a picture of the Lungs and learn more about the health topic.
Small Cell Lung Cancer vs. Non-Small Cell Lung CancerNon-small cell lung cancers (NSCLC) consist of large cell carcinomas, adenocarcinomas, and squamous cell carcinomas. Small cell lung cancer (SCLC) usually starts in the bronchi and typically appears in those who smoke. SCLC and NSCLC are staged in different manners, and SCLC tends to metastasize more quickly than NSCLC. Signs and symptoms of NSCLC and SCLC include shortness of breath, coughing up blood, recurring lung infections, and chest pain. Treatment may involve radiation therapy, chemotherapy, and surgery.
Sepsis (Blood Poisoning)Sepsis (blood poisoning) is a potentially deadly infection with signs and symptoms that include elevated heart rate, low or high temperature, rapid breathing and/or a white blood cell count that is too high or too low and has more than 10% band cells. Most cases of sepsis are caused by bacterial infections, and some cases are caused by fungal infections. Treatment requires hospitalization, IV antibiotics, and therapy to treat any organ dysfunction.

Trisomy 18Trisomy 18, also known as Edwards syndrome, is a rare genetic disorder that causes severe birth defects in newborns. Signs and symptoms of trisomy 18 include heart and kidney defects, clenched fists, abnormalities of craniofacial structures, and more. Many times, cases of trisomy 18 are diagnosed in utero with the use of pregnancy screening tests. Treatment of the condition is aimed at improving the quality of life for affected infants. The average lifespan for an affected infant is 3 days to 2 weeks.
