Acute respiratory distress syndrome (ARDS) is a severe lung condition. It occurs when fluid fills up the air sacs in your lungs. Too much fluid in your lungs can lower the amount of oxygen or increase the amount of carbon dioxide in your bloodstream. ARDS can prevent your organs from getting the oxygen they need to function, and it can eventually cause organ failure.

ARDS most commonly affects hospitalized people who are very ill. It can also be caused by serious trauma. Symptoms usually occur within a day or two of the original illness or trauma, and they may include extreme shortness of breath and gasping for air.

体育投注网址ARDS is a medical emergency and a potentially life-threatening condition.

The symptoms of ARDS typically appear between one to three days after the injury or trauma.

体育投注网址Common symptoms and signs of ARDS include:

体育投注网址ARDS is primarily caused by damage to the tiny blood vessels in your lungs. Fluid from these vessels leaks into the air sacs of the lungs. These air sacs are where oxygen enters and carbon dioxide is removed from your blood. When these air sacs fill with fluid, less oxygen gets to your blood.

体育投注网址Some common things that may lead to this type of lung damage include:

  • inhaling toxic substances, such as salt water, chemicals, smoke, and vomit
  • developing a severe blood infection
  • developing a severe infection of the lungs, such as pneumonia
  • receiving an injury to the chest or head, such as during a car wreck or contact sports
  • overdosing on sedatives or tricyclic antidepressants

ARDS is usually a complication of another condition. These factors increase the risk of developing ARDS:

体育投注网址ARDS can be a more serious condition for people who:

体育投注网址If you suspect that someone you know has ARDS, you should call 911 or take them to the emergency room. ARDS is a medical emergency, and an early diagnosis may help them survive the condition.

A doctor can diagnose ARDS in several different ways. There’s no one definitive test for diagnosing this condition. The doctor may take a blood pressure reading, perform a physical exam, and recommend any of the following tests:

体育投注网址Low blood pressure and low blood oxygen can be signs of ARDS. The doctor may rely on an electrocardiogram and echocardiogram to rule out a heart condition. If a chest X-ray or CT scan then reveals fluid-filled air sacs in the lungs, a diagnosis for ARDS is confirmed.

体育投注网址A lung biopsy can also be conducted to rule out other lung diseases. However, this is rarely done.

体育投注网址 of people with ARDS die from it. However, the risk of death isn’t the same for all people who develop ARDS. The death rate is linked to both the cause of ARDS and the person’s overall health. For example, a young person with trauma-induced ARDS will have a better outlook than an older person with a widespread blood infection.

体育投注网址Many survivors of ARDS fully recover within a few months. However, some people may have lifelong lung damage. Other side effects may include:

  • muscle weakness
  • fatigue
  • an impaired quality of life
  • compromised mental health

There’s no way to prevent ARDS completely. However, you may be able to lower your risk of ARDS by doing the following:

  • Seek prompt medical assistance for any trauma, infection, or illness.
  • Stop smoking cigarettes, and stay away from secondhand smoke.
  • Give up alcohol. Chronic alcohol use may increase your mortality risk and prevent proper lung function.
  • Get your flu vaccine annually and pneumonia vaccine every five years. This decreases your risk of lung infections.
