Spirometry

Alternative names:

pulmonary function tests; spirogram

What the risks are:

The risk is minimal for most people. There is a small risk of collapsed lung in people with a certain type of lung disease. The test should not be given to people with a recent heart attack and in certain other types of heart disease.

Special considerations:

Cooperation from the patient performing the test is crucial in providing accurate results.
A poor seal around the mouthpiece of the spirometer can give poor results.
Do not smoke before the test.
