Print pageAre there any side-effects when performing lung function tests?
There should not be any side-effects from carrying out these tests.
As you are usually asked to perform the breathing exercises a few times, you may feel a little tired after the tests have been completed – this is quite normal and you should not worry.
The tired feeling will quickly disappear. However, if you have any chest pain or other problems during the tests, please tell a nurse.
Your lung function test results and a report, if needed, will usually be available almost immediately after the tests have been completed.
You can either take these results with you to the clinic or ward or they can be sent for you.
Do’s and don’ts
- Do wear loose clothing which does not restrict your chest and abdominal movement.
- Do not smoke for at least 24 hours before the tests.
- Do not perform vigorous exercise for at least 30 minutes before the tests.
- Do not eat a large meal during the two hours before the tests. Please do not drink alcohol during the four hours before the tests.
