A Comprehensive Guide to Pulmonary Edema

Our lungs are responsible for taking in oxygen and releasing carbon dioxide with the help of tiny air sacs called alveoli. Alveoli have thin, permeable walls that allow for the efficient exchange of gasses.

In pulmonary edema, also known as lung congestion, is a serious condition that occurs when fluid accumulates in the lungs’ air sacs (alveoli). This excess fluid makes it difficult for oxygen to pass into the bloodstream, leading to shortness of breath and other respiratory problems.

Symptoms of Pulmonary Edema

1. Acute pulmonary edema;

  • Sudden, severe shortness of breath, even at rest
  • Rapid, shallow breathing
  • Coughing up pink or frothy mucus
  • Wheezing
  • Chest tightness or discomfort
  • Anxiety or feeling of panic
  • Rapid heartbeat
  • Feeling unusually sweaty or cold

2. Chronic pulmonary edema;

  • Shortness of breath that worsens with activity and improves with rest
  • Difficulty lying down at night
  • Frequent need to urinate at night
  • Fatigue and weakness
  • Swollen ankles

3. High-altitude pulmonary edema;

  • Gradual onset of shortness of breath, usually within 24-48 hours of reaching high altitude
  • Dry cough
  • Fatigue
  • Headache
  • Dizziness

When to see a doctor

Early diagnosis and treatment are crucial for better treatment seek immediate medical attention if you feel these symptoms;

  • Sudden, severe shortness of breath
  • Difficulty breathing, even at rest
  • Coughing up pink or frothy mucus
  • Chest pain or tightness

Causes

There are several factors that can contribute to the development of pulmonary edema. Let’s talk about the two main categories:

  1. Heart-related (cardiogenic) pulmonary edema

The most common type of pulmonary edema is caused by a weakened heart that struggles to pump blood efficiently and leads to fluid backup in the lungs.

  • Congestive heart failure
  • Heart valve disease
  • High blood pressure
  1. Non-heart-related (noncardiogenic) pulmonary edema

This is the type of pulmonary edema that is not related to heart problems and can be caused by various factors like kidney disease, high altitude exposure, or severe allergic reactions.

  • Acute respiratory distress syndrome
  • High-altitude pulmonary edema
  • Kidney disease
  • Severe allergic reactions

Complications of Pulmonary Edema

  • Acute respiratory failure
  • Respiratory arrest
  • Cardiac arrest

Prevention of Pulmonary Edema

  • Quit Smoking
  • Exercise Regularly
  • Maintain a Healthy Weight
  • Control Blood Pressure
  • Manage Heart Conditions
  • Avoid Rapid Ascent at High Altitudes
