慢性阻塞性肺疾病是由肺部的氣管炎或肺氣腫造成的一種病症。 它會導致呼吸道堵塞，和呼吸困難。 美國每年約有14萬人死於慢性阻塞性肺疾病，每4分鐘約有1個死亡個案。大多數在年齡65至74歲之間的人有較高的風險患有慢性阻塞性肺疾病。此外，75％的慢性阻塞性肺疾病的死因是同吸煙有關，而25％的慢性阻塞性肺疾病的死因是同吸二手煙或其他情況造成的。

Chronic Obstructive Pulmonary Disease (COPD) is a lung condition caused by two types of infections: bronchitis and emphysema. Both block the airway, making breathing difficult. Each year the U.S. has about 140,000 COPD-related deaths, or approximately 1 death every 4 minutes. People with asthma or between ages 65 and 74 have a higher risk of developing COPD. Furthermore, 75% of COPD deaths are caused by smoking, and 25% are caused by either second-hand smoking or other conditions.
