Pulmonary Edema: Care Instructions

Normal and inflamed airways


Pulmonary edema is the buildup of fluid in the lungs. It usually occurs when the heart does not pump blood through the body properly. Pulmonary edema can also be caused by another disease, such as liver or kidney failure. It can also happen at high altitudes, from a poisoning, or as a result of a non-fatal drowning.

If you have fluid in your lungs, you may have trouble breathing, be restless, have a fast heart rate, or cough up foamy pink fluid. Breathing problems may be worse when you lie down.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?


  • Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you think you are having a problem with your medicine.
  • Review all of your regular medicines with your doctor. Do not take any natural health products without talking to your doctor first.


  • Eat a balanced diet. Make an appointment with a dietitian if you have questions about what type of diet might be best for you.
  • Do not eat more than 2,000 milligrams (mg) of sodium each day. That is less than 1 teaspoon of salt a day, including all the salt you eat in prepared or packaged foods.
    • Do not add salt while you are cooking or at the table. Flavour with garlic, lemon juice, onion, vinegar, herbs, and spices instead of salt.
    • Eat fewer processed foods and foods from restaurants, including fast food.
    • Use fresh or frozen foods instead of canned.
    • Count and record how much sodium you eat each day. Check food labels for sodium.
    • Ask your doctor before using salt substitutes that have potassium, such as Lite Salt.


  • Stay out of air pollution; smog; cold, dry air; hot, humid air; and high altitudes.
  • Learn breathing methods that help the airflow in and out of your lungs.
  • Take rest breaks often. Schedule short rest breaks when doing housework and other activities. An occupational therapist or physiotherapist can help you find ways to do everyday activities with less effort.
  • Start light exercise if your doctor says it is okay. Try to stay as active as possible. If you have not exercised in the past, start out slowly. Walking is a good way to start.
  • Get enough rest at night. Sleeping with 1 or 2 pillows under your upper body and head may help you breathe easier at night.
  • Discuss rehabilitation with your doctor. Find out what programs are available in your area.
  • Do not smoke or use other tobacco products. Smoking can make your condition worse. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
  • Do not use alcohol or illegal drugs.

When should you call for help?

Call 911 anytime you think you may need emergency care. For example, call if:

  • You have severe trouble breathing.
  • You passed out (lost consciousness).
  • You have symptoms of a heart attack. These may include:
    • Chest pain or pressure, or a strange feeling in the chest.
    • Sweating.
    • Shortness of breath.
    • Nausea or vomiting.
    • Pain, pressure, or a strange feeling in the back, neck, jaw, or upper belly or in one or both shoulders or arms.
    • Light-headedness or sudden weakness.
    • A fast or irregular heartbeat. Pain that spreads from the chest to the neck, jaw, or one or both shoulders or arms.

After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.

Call your doctor or nurse advice line now or seek immediate medical care if:

  • You have trouble breathing or have wheezing that is getting worse.
  • You are coughing more deeply or more often.
  • You cough up blood.
  • You get a fever.
  • You have more swelling in your legs or belly.
  • Your symptoms are getting worse.

Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if you have any problems.
