Lung Function Tests
Lung Function Test / Spirometery:
Spirometry is a simple test used to help diagnose and monitor certain lung conditions by measuring how much air and how well, you breathe in and out.
It’s carried out using a device called a Spirometer which is a small machine attached by a cable to a mouthpiece.
You should avoid smoking for 24 hours before the test and also avoid drinking alcohol, strenuous exercise or eating large meals for a few hours beforehand. It is best to wear loose comfortable clothing on the day of the test and please remember bring any inhalers with you.
What Will Happen at my Lung Function Test
To start, we will measure your height and weight. You will then be seated during the test and a soft clip will be placed on your nose to prevent air escaping from it. The staff member will then explain the procedure fully.
When you’re ready, you will be asked to take a deep breath, close your lips tightly around the mouthpiece and then gently blow into the tube - you will be expected to do this a minimum of three times to ensure a reliable result. Then you will be asked to do the same again, but this time you will be asked to blow out as quickly as possible.
If your doctor wishes to measure the effectiveness of your inhalers you will then be advised to take them and wait for 15 minutes in reception. After this 15 minute break, you will be asked to perform the two tests again.
All results will be sent to your doctor for review.
