RHS provides comprehensive testing for Pulmonary Function. Our trained specialists will take you step by step through your appointment. Using a Spirometry test, also called a pulmonary function test or lung function test, we will be able to provide you and your doctor specific details for your needs with oxygen or other lung and pulmonary needs.

What is Spirometry?

Spirometry testing is a common, reliable and effective diagnostic tool used to measure lung function. It tests for COPD (Chronic Obstructive Pulmonary Disease), Asthma and other lung conditions. It measures how much air one can breathe in and how fast it can be blown back out. The results are then compared to what an individual’s normal values should be. Spirometry is the most common of several tests that can be done to determine lung function.

Why is Spirometry Important?

Spirometry can be used to help in diagnosing lung conditions. It is also a great tool to better help your doctors manage your lung health. Spirometry can help determine severity of disease, progression of your condition, or how well breathing medications or treatment is working.

Who Should Have Spirometry Testing?

If you suffer from Asthma and have never had spirometry. If you’ve had previous spirometry done and wanting to know any changes. If you currently smoke, previously smoked, or thinking about quitting smoking. If you have any lung condition, such as COPD, and want to check the progression of your condition. If you would like to determine how well your current treatment is working.

How are my lungs doing? If you have ever asked this question then you should have Spirometry testing!

You don’t need to currently have a lung condition before doing Spirometry. Spirometry can help determine or rule out breathing issues. It is a great test to help your physician in assessing your lung function and overall health.


How to prepare for your test:

  • No smoking one hour before the test.
  • No alcohol within four hours of test.
  • Do not eat a large meal within two hours of test.
  • Please wear loose, comfortable clothing.
  • Avoid vigorous exercise within 30 minutes of test.
  • If you are currently prescribed inhalers/puffers, you may be asked to avoid taking them a few hours before spirometry. Ask your doctor (or the center performing the test) beforehand if this applies to you.


The Test

What happens at the test?

  • The test is painless and takes around 10-30 minutes. Spirometry testing can often be done in your doctor’s office or nearby clinic.
  • During testing you will be asked to do several breathing maneuvers into a mouthpiece while wearing a nose clip. You will be doing this several times for accurate results. Instructions will be given and you will be coached throughout testing. You may also be given breathing medication. To determine if your lungs responded to the medication, testing may be repeated.



Your Results will be communicated with your Doctor and we can discuss treatment options. We will share with your doctor the results from your spirometry test.

What does this test measure?

Two of the most common measurements looked at during Spirometry:

  • Forced Vital Capacity – The largest amount of air that you can blow out after you take your biggest breath in.
  • Forced Expiratory Volume – The amount of air you can blow out of your lungs in the first second.

These measurements along with other data is gathered during testing. Your doctor is then informed the state of your lung function based on the results.

If you have questions or concerns about your lung health, talk to your doctor about Spirometry.
