Spirometry is a common test that evaluates how well your lungs are functioning, and it provides valuable information to help diagnose various respiratory conditions. But if you’re scheduled for a spirometry test, having questions is normal.
At Medical Associates Of North Texas, we specialize in pulmonary care in Fort Worth, Texas. We offer spirometry testing, and we believe that understanding what to expect can help you feel more prepared and at ease. Here’s what you can expect at your appointment.
Spirometry testing involves using a device called a spirometer to measure lung function. It measures the amount (volume) and speed (flow) of air you can inhale and exhale — and because it’s straightforward and noninvasive, it’s a widely used tool in diagnosing and monitoring lung conditions like asthma and chronic obstructive pulmonary disease (COPD).
During the test, you breathe into a mouthpiece connected to the spirometer. The device records the amount of air you breathe in and out, as well as how quickly you can exhale the air from your lungs. We use the results to evaluate your lung capacity and identify any airflow obstruction or restriction.
If you’re experiencing symptoms like persistent coughing, shortness of breath, wheezing, or chest tightness, we may recommend spirometry to diagnose what’s causing your symptoms. If you’re already diagnosed with a respiratory condition, spirometry helps monitor disease progression and the effectiveness of treatments.
Here’s a step-by-step guide to what happens at a spirometry testing appointment:
We will give you specific instructions on how to prepare for your test. Before your appointment, you may be advised to avoid heavy meals, smoking, or certain medications.
Remember to wear comfortable clothing that doesn’t restrict your breathing. When you arrive on your test day, you’ll complete some paperwork and provide a brief medical history. We’ll explain the test procedure and answer any questions you may have before we get started.
You take your spirometry test sitting down, and your technician places a clip on your nose to ensure no air escapes through your nostrils. Then, they ask you to seal your lips tightly around the mouthpiece of the spirometer.
You take a deep breath in and then exhale forcefully into the mouthpiece. This measures your forced vital capacity (FVC), which is the total amount of air you can exhale after taking the deepest breath possible.
You may be asked to repeat the breathing maneuvers a few times, with rest periods in between. Taking multiple readings helps ensure consistent and accurate results.
Once your spirometry test is over, you’re free to go home. You might experience mild dizziness or shortness of breath immediately after the test, but this should subside quickly.
The technician reviews your results and sends them to your doctor. We discuss the spirometry results with you at a follow-up appointment. We may diagnose a condition, adjust your treatment plan, or recommend further tests based on our findings.
