Asthma Breathing Test

Lung Function Testing.

Breathing tests, also known as spirometry or pulmonary function tests, are used to diagnose and monitor asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases.

You will be asked to blow into a machine that will measure the volume of air leaving the lungs. A nurse will coach and encourage you to properly perform the test. You may be given a bronchodilator inhaler (Albuterol) to see if your breathing improves. After 15 minutes, the test will be performed again. After your spirometry is completed, Dr. Windom will discuss your results and recommend a treatment plan.

How do I prepare for the test?

Please arrive on time for your test.

If possible, wear non-restrictive clothing. It may help for you to remove a tie or belt for the test. There is no restriction on foods or liquids. There are certain medications that must be stopped for a period of time prior to the testing. Other medications will not affect the breathing test. If you have any questions about which medications you may or may not use, please call our office @ 941-927-4888.
