Spirometry Test: Understanding Lung Function

Breathing is something most of us take for granted—until it becomes difficult. If you’ve been experiencing a persistent cough, wheezing, or breathlessness, your GP may recommend a spirometry test. This simple yet powerful tool helps doctors measure how well your lungs are working and spot any early signs of conditions like asthma, COPD, or other lung diseases.

In this blog, we’ll explore what a spirometry test is, how it works, what the results mean, and practical things like how much it costs and how long it takes.

What Is a Spirometry Test?

A spirometry test is a common lung function test that measures how much air you can breathe in and out, and how quickly you can do it.

It’s often used to:

• Diagnose conditions such as asthma, COPD, and other breathing problems
• Monitor existing lung conditions
• Assess the effectiveness of treatment
• Check lung function before surgery or as part of a health check

At the Private Medical Clinic, we regularly use spirometry as part of our respiratory and health screening services to give patients a clear picture of their lung health.

How to Perform a Spirometry Test

The test is straightforward, safe, and completely non-invasive. Here’s what typically happens during the appointment:

1. Preparation – You’ll be seated comfortably, and your doctor or nurse will explain the process. You may be asked to avoid smoking or using inhalers for a few hours before the test.
2. Breathing into the device – You’ll be given a special mouthpiece connected to the spirometer. You’ll take a deep breath in and blow out as hard and fast as possible.
3. Repeating the test – The test is usually repeated several times to ensure the results are consistent.
4. Recording results – The spirometer records the volume and speed of your breath, which your doctor will interpret.
   
   

It only takes a few minutes, and you can get your spirometry test results on the same day.

Understanding Spirometry Test Results

Your spirometry test results will show two key numbers:

• FEV1 (Forced Expiratory Volume in 1 second) – how much air you can forcefully breathe out in one second.
• FVC (Forced Vital Capacity) – the total amount of air you can breathe out after taking a deep breath.

The ratio of FEV1 to FVC helps doctors identify whether your lung function is normal or if there are signs of narrowing or obstruction in the airways.

• Normal results – Suggest healthy lung function.
• Lower than normal results – Could indicate asthma, COPD, or another lung condition.

Your doctor will explain the results in plain English and, if needed, recommend further tests or treatment.
