On this page, you will find everything you need to know about pulmonary edema.
What is pulmonary edema?
Pulmonary edema is the abnormal accumulation of fluid in the lungs, which leads to difficulty or shortness of breath. This fluid builds up when the heart does not pump blood effectively, allowing it to back up into the veins that carry blood from the lungs.
What are the symptoms of pulmonary edema?
Symptoms may appear suddenly or develop gradually:
Sudden symptoms:
- Difficulty breathing or severe shortness of breath.
- Feeling of suffocation, especially when lying down.
- Cough producing frothy sputum, which may contain blood.
- Heart palpitations or rapid heartbeat.
- Feeling anxious or uncomfortable.
- Cold or clammy skin.
- Wheezing or gasping for air while breathing.
Chronic symptoms:
These may include the previous symptoms in addition to:
- Swelling in the legs and feet.
- Rapid weight gain.
- Shortness of breath during physical activity.
- Waking up at night due to shortness of breath.
- Fatigue
- Chest pain.
What causes pulmonary edema?
Pulmonary edema occurs when the heart is unable to pump blood efficiently, causing fluid to back up into the lungs. Causes include:
Heart and cardiovascular-related causes:
- Congestive heart failure.
- Heart attack.
- Narrowed heart valves or weakened heart muscles.
- Irregular heart rhythms.
- Myocarditis (inflammation of the heart muscle).
- Severe and sudden high blood pressure.
Other medical conditions and causes:
- Pneumonia
- Sepsis (blood infection), when the body has a poor response to infection.
- Certain medications.
- Kidney failure.
- Narrowing of the arteries supplying the kidneys.
- Lung damage caused by exposure to toxic gases or severe infections.
- Trauma
- High-altitude exposure, such as mountain climbing.
How is pulmonary edema diagnosed?
The doctor will take a detailed medical history and perform a physical examination. Additional tests may include:
- Blood tests.
- Blood oxygen level measurements.
- Chest X-ray.
- Electrocardiogram (ECG).
- Echocardiogram (heart ultrasound).
How is pulmonary edema treated?
Treatment depends on the cause and is usually done under emergency and intensive medical care. It may include:
- Diuretics
- Blood pressure medications.
- Intravenous medications to strengthen the heart’s pumping ability.
In severe cases:
- Oxygen therapy.
How can pulmonary edema be prevented?
- Take medications exactly as prescribed by your doctor.
- Have regular follow-ups, especially if you have breathing problems.
- Follow a low-sodium (low-salt) healthy diet.
- Quit smoking.
- Maintain a healthy weight.
What are the complications of pulmonary edema?
Fluid accumulation in the lungs is a serious threat to health. Complications vary depending on the cause, but common ones include:
- Difficulty breathing.
- Swelling in the legs and feet.
- Fluid buildup around the lungs (pleural effusion).
- Liver congestion and swelling.
When should you see a doctor?
Seek emergency care immediately if you experience sudden symptoms such as:
- Feeling of suffocation.
- Irregular heartbeat.
- Coughing up blood.
- Bluish discoloration of the skin.
- Excessive sweating.
