What is Spirometry

Spirometry is a lung function test that measures the size of your lungs (volume) and the speed you can move air out of your lungs (flow). This test helps to diagnose a number of lung conditions, including asthma and COPD.

What is the testing like?

Spirometry takes roughly 45 minutes to complete. The test is not painful, but does require effort to complete it properly. The test is performed sitting in a chair and breathing through a mouthpiece that records the air movement through it. You will be asked to breathe normally for a few breaths, followed by taking the largest breath in that you can and then blasting the air out as hard and as fast as you can. You will be coached through the test and given feedback to make sure we collect the best information we can. You will likely be given an inhaled medication part way through the testing, then perform more efforts. This medication helps identify important information about your lungs with and without the medication, similar to a before-and-after type picture.

You may be asked to withhold certain inhaled medications that could interfere with the testing. You do not need to stop taking your regular daily medications.

Medications to Withhold

You will be asked to refrain from smoking at least an hour before your test.

When you should reschedule your appointment:

• If you are experiencing an acute respiratory infection
• If you have suffered a heart attack or stroke within the last
• If you have had abdominal, chest, or eye surgery in the last 6 weeks
• If you have suffered a recent collapsed lung.

Talk to you Doctor before booking for an appointment if:

• You have a known aneurysm
• You have uncontrolled high blood pressure (hypertension).

What happens after the test?

The test data is sent to a Respirologist for interpretation. Once the interpreted results are available, a copy will be sent to your family physician, as well as the ordering physician if applicable. TrueNorth does not receive copies of the interpreted tests.
