A history of heavy smoking alone is not enough for a physician to differentiate emphysema from other respiratory diseases. A physician will combine information on symptoms, medical history, physical examination, lung function tests, and chest x ra...

A variety of pulmonary function tests may be ordered. In the early stages of emphysema, the only result may be dysfunction of the small airways.
|
|
|
A diagnosis of emphysema will not be made on the basis of the above symptoms alone. A detailed medical history will be taken along with x rays and pathology examinations.

This test tells how much air moves in and out of your lungs when you exercise. During the test, you may be asked to walk on a treadmill or ride on a stationary bike. The test may locate where your breathing problems begin. They may begin in the lungs, the heart, or both. Your test results can also show a safe activity level for you.

Normal individuals have a large reserve in lung function that allows breathing capacity to increase at least twenty to thirty times during periods of vigorous physical activity. It is not the ability to breathe that normally limits maximum exercis...

During a physical examination, a health care provider studies a patient''s body to determine the presence or absence of physical problems.
|
|
A pulmonary function test shows how well your lungs are working. A complete test has three parts. You may be given the entire test or only certain parts. The entire test is painless and lasts 45–90 minutes.
|
|
You and your health care provider can use information from a peak-flow meter to help stop a flare-up in its tracks.
|
|
Each time you blow into your peak flow meter, you get a number. The number tells you what zone you're in: green, yellow, or red. When you take your peak flow and find your zone, do what your action plan tells you to do.
|
|
Monitoring your peak flow can help tell you how open your airways are—even before you have symptoms. It's done with a device called a peak flow meter. Your peak flow is how fast you can push air out of your lungs at any one time.
