Spirometry Test
A simple non-invasive test of lung capacity and lung function. Spirometry is a common diagnostic test used to assess how quickly you can move air into and out of your lungs.
What is spirometry?
Spirometry assesses whether your airways are obstructed or if the movement of your lungs is restricted. It may be recommended if you're experiencing breathlessness or a persistent cough, or if you may have asthma.
Spirometry is also used to monitor treatment for an existing condition.
Need to know
The test involves taking a very deep breath and then exhaling into the mouthpiece of a specialised instrument called a spirometer. The spirometer measures how much air you can push out of your lungs in one breath.
You'll sit comfortably during the test and do a few practice breaths so you understand what's involved. Your physiologist might place a soft clip on your nose to make sure you exhale fully through your mouth. You may need to repeat the test a couple of times to ensure an accurate reading.
Your consultant will explain the test to you and answer any questions you may have. They'll let you know if there is anything specific you need to do to prepare. This may include avoiding certain medications, caffeine, smoking, large meals or vigorous exercise before your test.
Your consultant will review the results of the test with you and let you know if any other assessments are needed. If you're undergoing treatment for an existing lung condition, you may need to return for another spirometry in the future to see if your condition has improved.
