Abstract

Chronic obstructive airway disease (COPD) is common in most communities of the world. In US it is the fourth leading cause of chronic morbidity and mortality, while it is projected that it will be the third leading cause of death worldwide by 2020. With rising incidence of smoking, urbanization and lack of proper health care, it should be no surprise that we continue to see more and more cases of the disease by the years.
