Acute respiratory distress syndrome



Other Names:
ARDS; Acute lung injury; ALI; ARDS; Acute lung injury; ALI; Adult respiratory distress syndrome; Respiratory distress syndrome, adult; Increased-permeability pulmonary edema; Non-cardiogenic pulmonary edema; Shock lung; Stiff lung See More

Acute respiratory distress syndrome (ARDS) is a life-threatening lung condition that prevents enough oxygen from getting to the lungs and into the blood. [1] People who develop ARDS often are very ill with another disease or have major injuries.[2] The condition leads to a buildup of fluid in the air sacs which prevents enough oxygen from passing into the bloodstream. Symptoms may include difficulty breathing, low blood pressure and organ failure, rapid breathing and shortness of breath.[1]

Typically people with ARDS need to be in an intensive care unit (ICU).[1][2] The goal of treatment is to provide breathing support and treat the cause of ARDS. This may involve medications to treat infections, reduce inflammation, and remove fluid from the lungs. A breathing machine is used to deliver high doses of oxygen and continued pressure called PEEP (positive end-expiratory pressure) to the damaged lungs. Patients often need to be deeply sedated with medications when using this equipment. Some research suggests that giving medications to temporarily paralyze a person with ARDS will increase the chance of recovery. Treatment continues until the patient is well enough to breathe on his/her own.[1]

More detailed information about the treatment of ARDS can be accessed through the National Heart, Lung and Blood Institute (NHLBI) and Medscape Reference
An article detailing Oxygen Therapy is also available.

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Acute respiratory distress syndrome. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
