Spirometry

Spirometry is a simple test used to help diagnose and monitor certain lung conditions by measuring how much air you can breathe out in one forced breath.

It’s carried out using a device called a spirometer, which is a small machine attached by a cable to a mouthpiece.

Why spirometry is carried out

Spirometry can be used to help diagnose a lung condition if you have symptoms, or if your doctor feels you’re at an increased risk of developing a particular lung condition.

For example, spirometry may be recommended if you have a persistent cough or breathlessness, or if you’re over 35 and smoke.

Conditions that can be picked up and monitored using spirometry are:

If you’ve already been diagnosed with 1 of these conditions, spirometry may be carried out to check the severity of the condition or see how you’re responding to treatment.

What happens during a spirometry test

You’ll be seated during the test and a soft clip will be placed on your nose to stop air escaping from it.

The tester will explain what you need to do, and you may be asked to have a few practise attempts first.

 

When you’re ready for the test, you’ll be asked to:

  • inhale fully, so your lungs are completely filled with air
  • close your lips tightly around the mouthpiece
  • exhale as quickly and forcefully as you can, making sure you empty your lungs fully
  • This will normally need to be repeated at least 3 times to ensure a reliable result.

Sometimes, the test may need to be repeated around 15 minutes after taking some inhaled bronchodilator medicine. This is referred to as Spirometry with Reversibility.

This can show if you have a lung condition that responds to these medicines.

 

Overall, your appointment should last around 30 to 60 minutes. You’ll be able to go home soon after the tests have finished and return to your normal activities.
