Spirometry FAQs | NOVA Pulmonary

What is spirometry?

Spirometry is a common pulmonary function test that measures how well your lungs work by assessing how much air you can inhale and exhale, and how quickly you can breathe out.

Why is spirometry performed?

Spirometry is used to diagnose and monitor lung conditions such as Asthma and Chronic Obstructive Pulmonary Disease (COPD). It also helps evaluate symptoms like shortness of breath, chronic cough, and wheezing.

How does a spirometry test work?

During the test, you will breathe into a mouthpiece connected to a machine called a spirometer. You’ll be asked to take a deep breath and exhale as forcefully and completely as possible.

Is spirometry painful?

No, spirometry is a non-invasive and painless test. Some patients may feel slightly lightheaded from deep breathing, but this usually resolves quickly.

How long does a spirometry test take?

The test typically takes about 15 to 30 minutes, including preparation and multiple breathing attempts to ensure accurate results.

Do I need to prepare for a spirometry test?

Yes, your provider may recommend:

• Avoiding heavy meals before the test
• Not smoking for several hours beforehand
• Avoiding certain medications (if instructed)
• Wearing comfortable clothing

What do spirometry results show?

Spirometry measures key values such as:

• Forced Vital Capacity (FVC)
• Forced Expiratory Volume in 1 second (FEV1)

These results help determine if there is airflow obstruction or restriction in your lungs.

What conditions can spirometry detect?

Spirometry can help diagnose:

• Asthma
• Chronic Obstructive Pulmonary Disease
• Pulmonary Fibrosis
• Bronchiectasis

Can spirometry detect lung cancer?

Spirometry does not diagnose Lung Cancer, but it can detect abnormal lung function that may prompt further testing such as imaging studies.

What is a normal spirometry result?

Normal results depend on age, height, gender, and ethnicity. Your pulmonologist will compare your results to predicted values to determine if your lung function is within a healthy range.

What happens if my spirometry results are abnormal?

If results are abnormal, your provider may recommend additional tests, medications, or treatments depending on the underlying condition.

Can children have spirometry tests?

Yes, spirometry can be performed on children, typically those aged 5 years and older, who are able to follow breathing instructions.

How often should spirometry be done?

The frequency depends on your condition. Patients with chronic lung diseases like Chronic Obstructive Pulmonary Disease may need regular testing to monitor disease progression.

Is spirometry safe?

Yes, spirometry is a safe and routine test. It is widely used in pulmonary care with minimal risk.
