Chronic Obstructive Pulmonary Disease (COPD) is the third leading cause of death in the United States. The disease affects more than 11 million individuals, and there is currently no cure for COPD. It is defined as a chronic inflammatory disorder of the lungs that is mainly caused by smoking. COPD changes the normal function of the lungs. A patient with COPD has less air flowing in and out of the airways. These individuals also use most of their energies in breathing since it is harder for them to get oxygen. The airways of individuals with COPD are clogged with mucus which decreases their ability to eliminate carbon dioxide and bring oxygen inside the body.

Affecting more than 11 million individuals, there is still no cure for this fatal disease (American Lung Association, 2014). The National Institute of Health (2013), states that COPD is a “progressive” disease that makes it hard for a patient to breathe. According to Itoh and colleagues (2013), COPD is defined as, “a chronic inflammatory disorder of the lung and whole body caused mainly by tobacco smoking.” There are two types of COPD: chronic bronchitis and emphysema.
Lung Function and COPD
The lungs are complex elastic organs that work by exchanging carbon dioxide (gas that the body needs to remove) for oxygen (gas that the body needs). When we inhale, the diaphragm along with the intercostals muscles contract and expand the chest cavity. This process allows air to go inside the airways and inflates the lungs. When we exhale, the diaphragm and the intercostals muscles relax and allow the chest cavity to gets smaller. This process enables air to flow out of the airways and the lungs deflate (National Institute of Health, 2013). When a patient has COPD, less air is flowing in and out of the airways. The National Institutes of Health (NIH), best describe the reasons for this cause: “the airways and air sacs lose their elastic quality, the walls between many of the air sacs are destroyed, the walls of the airways become thick and inflamed, and the airways make more mucus than usual, which can
