Pulmonary function tests measure how well your lungs work. Depending on the test(s) ordered, they measure how much air your lungs can hold, how fast you can move air, and how well oxygen moves in and out of your lungs. Your doctor may prescribe a pulmonary function test in order to:

• Diagnose lung diseases
• Monitor how lung diseases change over time
• Find the right treatment for lung diseases

What to expect during a pulmonary function test

Preparing for your procedure
Your physician will give you specific instructions prior to your test; however, it is important for you to abstain from smoking, vaping and/or water pipe use within one hour prior to your test. Do not consume intoxicants within 8 hours of testing as it may affect your ability to perform the test. In addition, you should not eat a large meal before your test or wear tight clothing that may restrict chest movement. If possible, avoid exercise and cold air exposure before the test. Also check with your physician to make sure you can continue to take your medications before the test.

During your procedure
You will be in a seated position during the test, and your technician will instruct you on how to use the specialized equipment. You might feel lightheaded, tired or short of breath during the test; if so, you can take rests as needed. Sometimes you will be given inhaled medication to determine if it can improve your lung function.

After your procedure
You may feel tired after the test so you should get plenty of rest prior to testing. You can return to normal activities after testing. The doctor will compare your test results with predicted values based on your age, gender, height and race to determine if your lungs are working properly.
