Copd: Prevent Exacerbations


An exacerbation of COPD

means your symptoms get much worse very quickly and can become life-threatening. Exacerbations can be triggered by infections such as a cold or the flu. Lung irritants such as air pollution, dust, fumes, or smoke can also be triggers.

Go to pulmonary rehabilitation (rehab) if directed:

Rehab is a program run by specialists who help you learn to manage COPD. Examples include a pulmonologist (lung specialist), dietitian, or exercise therapist. The specialists will help you make a plan to avoid triggers that cause an exacerbation.

Protect yourself from germs:

Germs can get into your lungs and cause an infection. An infection in your lungs can create more mucus and make it harder to breathe. An infection can also create swelling in your airway and prevent air from getting in. You can decrease your risk for infection by doing the following:

  • Wash your hands often with soap and water. Carry germ-killing gel with you. You can use the gel to clean your hands when soap and water are not available.
  • Do not touch your eyes, nose, or mouth unless you have washed your hands first.
  • Always cover your mouth when you cough. Cough into a tissue or your shirtsleeve so you do not spread germs from your hands.
  • Try to avoid people who have a cold or the flu. If you are sick, stay away from others as much as possible.

Do not smoke:

If you currently smoke, quitting is the best way to keep COPD from getting worse. Nicotine and other substances can cause lung irritation or damage and make it harder for you to breathe. Do not use e-cigarettes or smokeless tobacco. They still contain nicotine. It may be hard to quit smoking. Your healthcare provider can help you find resources if you need help to quit.

Avoid secondhand smoke:

This is smoke another person exhales. Even if you have never smoked or have quit, it is important to avoid secondhand smoke. This smoke can also cause lung damage or trigger an exacerbation.

Use pursed-lip breathing any time you feel short of breath:

  • Breathe in through your nose. Use the muscles in your abdomen to help fill your lungs with air.
  • Slowly breathe out through your mouth with your lips slightly puckered. You should make a quiet hissing sound as you breathe out.
  • Try to take 2 times as long to breathe out as to breathe in. This helps you get rid of as much air from your lungs as possible.
  • Repeat this exercise several times. When you are used to doing pursed-lip breathing, you can do it any time you need more air.
    Breathe in Breathe out

Take your medicines as directed:

Your healthcare provider may prescribe medicine to help you breathe easier. It is important that you take your medicines as directed to prevent or stop an exacerbation. Refill your medicines before you are out so that you do not miss a dose. Talk to your healthcare provider or pharmacist if you have any questions about how to take your medicines.

  • Short-acting bronchodilators may be called rescue inhalers or relievers. They relieve sudden, severe symptoms and start to work right away.
  • Long-acting bronchodilators may be called controllers or maintenance medicine. This medicine helps open your airway over time. It is used to prevent breathing problems. Long-acting bronchodilators should not be used to treat sudden, severe symptoms, such as trouble breathing.

Avoid anything that makes your symptoms worse:

Stay out of high altitudes and places with high humidity. Stay inside, or cover your mouth and nose with a scarf when you are outside in cold weather. Stay inside on days when air pollution or pollen counts are high. Do not use aerosol sprays, such as deodorant, bug spray, and hairspray.

Exercise daily:

Exercise for at least 20 minutes each day to help increase your energy and decrease shortness of breath. Talk to your healthcare provider about the best exercise plan for you.

Walking for Exercise

Drink more liquid:

Liquid will help to keep your air passages moist and help you cough up mucus. Mucus that stays in your lungs can make it harder to breathe when an exacerbation starts. Ask how much liquid to drink each day and which liquids are best for you.

Ask about vaccines:

Influenza (the flu) and pneumonia can become life-threatening for a person who has COPD. Your risk for exacerbations is higher if your lungs are infected. Get a flu vaccine each year as soon as it becomes available. The pneumonia vaccine may be given every 5 years, or as directed. Ask about other vaccines you may need and when to get them.
