The term COPD actually includes 2 different respiratory conditions: chronic bronchitis and emphysema. Bronchitis is a swelling of the airways. It typically causes a phlegmy cough and wheezing, and can make it hard to breathe. Emphysema involves damage to the air sacs in the lungs. It can cause shortness of breath and a tight feeling in the chest. To determine whether you have COPD, your doctor may perform a test called spirometry that measures how much air your lungs can hold and how forcefully you can breathe out.
