What happens in a spirometry test?

What to Expect

Spirometry is a painless test that can often be done in your doctor’s office or in a nearby clinic. The entire test usually takes less than 10 minutes, although sometimes it is repeated after taking a puffer medication.

You will be asked to breathe through a mouthpiece while wearing a nose clip. The tester will coach you to take in as big a breath as possible. You will then blast the air out as fast as you can until your lungs are completely empty. You may then be asked to take another deep breath in again. You will do this three times or more to make sure the results are accurate. You may also be given a medication to breathe in. The test would then be repeated to show if your lungs have responded to the medication.
