COPD

By Howard Bennett, RRT-SDS

Chronic Obstructive Pulmonary Disease, better known as COPD, is a long-term lung condition that makes it difficult for people to breathe. While it shares some similarities with asthma, the two conditions are not the same, though it is possible to have both at the same time. 

COPD is one of the leading causes of death in the United States. The good news is that the risk of developing it can be greatly reduced, most notably by avoiding smoking. 

What Is COPD?

COPD is a chronic lung disease that causes airflow blockage, impacting how well air moves in and out of the lungs. Most people with COPD actually have a combination of two conditions: 

Chronic Bronchitis 

Inflamed airways become swollen and clogged with mucus, restricting airflow. 

Emphysema 

The tiny air sacs (alveoli) in the lungs become damaged and lose elasticity, making it hard to exchange stale air for fresh air. 

Smoking is the primary cause of COPD, though long-term exposure to lung irritants can also contribute. 

How Healthy Lungs Work

In healthy lungs, stale air is consistently replaced with fresh air. 

When you inhale: 

  • Oxygen travels through the airways and into the tiny air sacs. 
  • Oxygen moves from the air sacs into the bloodstream. 
  • Carbon dioxide moves from the bloodstream into the air sacs. 

When you exhale: 

  • Carbon dioxide is pushed out of the air sacs, through the airways, and out through the nose or mouth. 
What Happens in COPD?

In COPD, oxygen has a harder time reaching the air sacs due to several changes in the lungs: 

  • Airways become inflamed and narrow 
  • Mucus builds up 
  • Air sacs become damaged 
  • The body doesn’t get enough oxygen, causing the heart to work harder 

These changes can make even simple activities—like walking or climbing stairs—feel exhausting. 

How COPD Affects Daily Life

COPD impacts both physical comfort and emotional well-being. 

Physical Effects 

  • Chronic coughing 
  • Shortness of breath 
  • Excess mucus production 
  • Wheezing due to narrowed airways 

Emotional Effects 

  • Feeling depressed, frustrated, or angry 
  • Avoiding activities due to shortness of breath or fatigue 
How COPD Is Diagnosed

Healthcare providers use several tools to diagnose COPD, including: 

  • Physical Exam: Evaluating breath sounds, reviewing medical and smoking history. 
  • Pulmonary Function Testing: Measures how much air you can exhale and how quickly, as well as total lung volume. 
  • Imaging and Other Tests: Chest X-rays, CT scans, EKGs, and blood tests may also be used. 
Treatment Options

While there is no cure for COPD, symptoms can be managed—and quality of life can significantly improve—with the right care. 

Quit Smoking 

For people who smoke, quitting is the most effective way to slow the progression of COPD.
(The longer you go without smoking, the more your lungs can recover from damage.) 

Medications 

Providers may prescribe: 

  • Bronchodilators 
  • Inhaled steroids 
  • Antibiotics (when needed) 

Oxygen Therapy 

For advanced COPD, supplemental oxygen may help improve breathing and energy levels. 

Regular Pulmonary Function Tests 

Yearly testing ensures that treatment plans remain effective and symptoms are properly managed. 

Living Well With COPD

Though COPD cannot be cured, partnering with a healthcare provider can help manage symptoms and support a healthier, more active life. Many people with COPD live well by following their treatment plan, avoiding lung irritants, and seeking help early when symptoms worsen.
