Chronic Obstructive Pulmonary Disease (COPD)

  201-833-3084    |      info@holyname.org


COPD is a term that refers to a group of lung diseases that can interfere with normal breathing. It is estimated that more than 11.6 million Americans suffer from COPD. It is the fourth leading cause of death in the US.

What are the different types of COPD? The two most common conditions of COPD are chronic bronchitis and emphysema.

  • Chronic bronchitis is a long-term inflammation of the bronchi (breathing passages in the lungs), which results in increased production of mucus, as well as other changes. These changes may result in breathing problems, frequent infections, cough, and disability.
  • Emphysema is a chronic lung condition in which alveoli (air sacs in the lungs) may be destroyed, narrowed, collapsed, stretched, or over-inflated. This can cause a decrease in respiratory function and breathlessness. Damage to the air sacs is irreversible and results in permanent "holes" in the lung tissue.

Some physicians agree that asthma should be classified as a chronic obstructive pulmonary disease, while others do not. A brief description of asthma is included below:

  • Asthma is a chronic, inflammatory lung disease involving recurrent breathing problems. The characteristics of asthma include the following:
    • the lining of the airways become swollen and inflamed
    • the muscles that surround the airways tighten
    • the production of mucus is increased, leading to mucus plugs


What causes COPD?

The causes of COPD are not fully understood. It is generally agreed that the most important cause of chronic bronchitis and emphysema is cigarette smoking. Other causes such as air pollution and occupational exposures may play a role, especially when combined with cigarette smoking. Heredity may also be a factor.

Rehabilitation for COPD:

The goals of COPD rehabilitation programs include helping the patient return to the highest level of function and independence possible, while improving the overall quality of life - physically, emotionally, and socially. Attaining these goals help people with COPD live more comfortably by improving endurance, providing relief of symptoms, and preventing progression of the disease with minimal side effects.

In order to reach these goals, COPD rehabilitation programs may include the following:
  • medication management
  • exercises to decrease respiratory symptoms and improve muscle strength and endurance
  • respiratory treatments to improve breathing ability
  • assistance with obtaining respiratory equipment and portable oxygen
  • methods to increase independence with activities of daily living (ADLs)
  • exercises for physical conditioning and improved endurance
  • stress management, relaxation exercises, and emotional support
  • smoking cessation programs
  • nutritional counseling
  • patient and family education and counseling
  • vocational counseling
