Pulmonary Function Testing Q & A

What is a pulmonary function test?

If you’re experiencing shortness of breath or a similar breathing problem, your doctor may recommend a pulmonary function test. Sometimes called a lung function test, this test shows whether your lungs are working properly or may require treatment to help improve your breathing.

Why is a pulmonary function test performed?

A pulmonary function test measures lung functions, such as how well your lungs deliver oxygen to your blood and how much air you’re able to take into your lungs, compared with people of the same age, gender, and height.

The doctors at Colorado Family Medicine perform pulmonary function tests for a number of reasons, including:


  • Identifying the reason for shortness of breath
  • Diagnosing lung diseases, such as bronchitis, emphysema, and asthma, in people with breathing problems
  • Ensuring that medication for a lung condition is working  

How is a pulmonary function test done?

The doctors at Colorado Family Medicine administer two types of pulmonary function tests. For the most accurate measurements, your doctor may perform both in a single visit.


For a spirometry reading, you breathe into a mouthpiece attached to a machine that measures both the amount and the speed of air entering and leaving your lungs.


During this test, you stand or sit inside an airtight box with clear walls. The test requires you to breathe or pant into a mouthpiece to measure the volume and capacity of your lungs. Your doctor may also place clips on your nostrils to see how well air moves out of your lungs.

What can I expect during a pulmonary function test?

Most people feel fine during and after the exams, but because you’re asked to breathe quickly at some points, your doctor monitors you closely in case you become dizzy or lightheaded, or you have trouble breathing.

Your doctor may give you a drug called a bronchodilator after some of the tests. The drug opens up your airways so your doctor can see how well your lungs perform with the aid of medication.

Breathing issues don’t have to negatively impact your quality of life. Call Colorado Family Medicine today or book an appointment online for a pulmonary function test.
