SARS (Severe Acute Respiratory Syndrome)
Medically reviewed by Drugs.com. Last updated on Dec 2, 2022.
Severe acute respiratory syndrome (SARS) is a condition caused by a virus that damages the air sacs of the lungs. The lung tissues become inflamed and scarred. The damaged air sacs do not allow oxygen to get into your bloodstream, which may cause respiratory failure. Respiratory failure means you cannot breathe well enough to get oxygen to the cells of your body. The SARS virus is related to other viruses that cause common colds and diarrhea. It may be found in saliva, sputum, or discharge from the nose of an infected person.

- Antivirals help treat or prevent a viral infection.
- Bronchodilators help open the air passages in your lungs, and help you breathe more easily.
- Antipyretics decrease a fever.
- Steroids lower inflammation to open your air passages so you can breathe easier.
- Blood samples may be tested for the amount of oxygen and carbon dioxide. The results can tell healthcare providers how well your lungs are working. Blood tests can also give healthcare providers information about how your body is working.
- X-ray pictures may be used to check for signs of infection, such as pneumonia.
- Breathing treatments help open your airway so you can breathe easier. A machine may be used to help you breathe in medicine.
- A ventilator is a machine that gives you oxygen and breathes for you when you cannot breathe well on your own. An endotracheal (ET) tube is put into your mouth or nose and attached to the ventilator. You may need a trach if an ET tube cannot be placed. A trach is a tube put through an incision and into your windpipe.
SARS is a serious, life-threatening disease, and treatment should not be delayed. If not treated early, the SARS virus may badly damage your lungs and cause more breathing problems. SARS may lead to pneumonia. Pneumonia causes the lungs to become swollen and filled with fluid. Fluid in the lungs causes severe shortness of breath and may lead to respiratory failure. Respiratory failure means you cannot breathe well enough to get oxygen to the cells of your body. This may affect your heart and brain and be life-threatening.
