Do you ever wonder how well your lungs are working? Whether you’re managing a known respiratory condition or simply prioritising your health, understanding your lung function is crucial. A spirometry test is a quick, non-invasive, and highly reliable way to assess your lungs’ performance.
What Is a Spirometry Test?
Spirometry is a common and essential lung function test that measures the volume of air you can inhale and exhale and how quickly you can expel it. It’s a cornerstone diagnostic tool for identifying and managing respiratory conditions like asthma, chronic obstructive pulmonary disease (COPD), and other airflow disorders.
Spirometry offers critical insights into lung health for individuals with existing respiratory conditions. Regular testing helps your doctor monitor the effectiveness of your current treatment plan and identify subtle changes in lung function early. This allows for timely adjustments to medications or therapies, improving outcomes and quality of life.
In addition to aiding diagnosis and treatment monitoring, spirometry can also be used as a preventive measure for individuals at risk of developing respiratory conditions, such as smokers or those exposed to occupational hazards. It’s a powerful tool for assessing lung health and taking proactive steps toward better breathing and overall well-being.
How Is a Spirometry Test Performed?
A spirometry test is typically completed in 15–30 minutes. The test involves taking a deep breath to fill your lungs, followed by a forceful and rapid exhalation into the spirometer’s mouthpiece. This exhalation should continue until your lungs feel empty. To ensure accurate results, you’ll repeat the process several times.
While spirometry is a straightforward test, proper technique is essential for accurate results. That’s why we’ll be with you every step of the way, demonstrating the correct method, providing guidance, and offering personalised support to ensure the test is practical and comfortable.
Understanding Your Spirometry Test Results
After completing a spirometry test, you’ll receive key measurements that offer valuable insights into your lung health:
- FVC (Forced Vital Capacity) measures the total air you can exhale forcefully after taking the deepest possible breath. It reflects your lung capacity.
- FEV1 (Forced Expiratory Volume in One Second) indicates how much air you can exhale in the first second of a forceful breath. It’s crucial for identifying conditions like asthma and COPD.
- FEV1/FVC Ratio compares the two values to assess airway function. A lower-than-normal ratio can suggest airway obstruction, which is often associated with asthma or COPD.
Your spirometry results are assessed against predicted values tailored to your age, height, gender, and ethnicity. These benchmarks help your doctor evaluate whether your lung function is within a healthy range or if there are signs of a potential respiratory issue.
Preparing for Your Spirometry Test
To ensure accurate results, there are several things you should do (or avoid) before your test:
- Avoid heavy meals and strenuous exercise for a few hours before the test, as these activities can impact your breathing capacity.
- Wear comfortable clothing that won’t restrict your breathing, and arrive at your appointment early to rest and catch your breath if you’ve been rushing.
- Don’t use any inhalers on the day of your test.
What to Expect After Your Spirometry Test
After completing your spirometry test, you can resume your normal activities immediately. Some people might feel slightly light-headed or tired immediately after the test, but this typically passes quickly.
Your respiratory scientist will process your results, and your doctor will review them along with your medical history and any symptoms you’ve been experiencing. They’ll use this information to make a diagnosis or adjust your current treatment plan if necessary.
Who Should Consider Getting a Spirometry Test?
Spirometry testing isn’t just for people with diagnosed breathing problems. You might benefit from a spirometry test if you:
- Experience unexplained shortness of breath
- Have a persistent cough
- Experience wheezing during exercise or at rest
- Are you a current or former smoker
- Work in environments with dust, chemicals, or other airborne particles
- Have a family history of lung conditions
- Need to monitor an existing respiratory condition
