Breathing is something we take for granted. Until it becomes hard.
Struggling to catch your breath? Or feeling like you’re constantly running out of air?
It is a sign that your lungs need attention. And you can examine them via spirometry. It’s a simple and effective way to check how your lungs are doing. Helping doctors diagnose and treat respiratory conditions early.
We have prepared this blog post for you to learn about spirometry procedure. Its significance and interpretation of results.
At Main Street Medical Centre. We know how frustrating it is to deal with health uncertainties. That’s why we offer reliable, GP-led diagnostic services like performing spirometry. All delivered with care and empathy. So, you can get accurate tests and expert advice in a comfortable setting.
Let’s move toward the topic.
What is Spirometry?
Spirometry is a simple test used to assess lung function. By measuring how much air you can inhale and exhale and how quickly. Healthcare providers use a specialised machine called spirometer. To evaluate airflow and detect abnormalities in lung function. This information helps in the diagnosis and management of respiratory conditions.
Spirometry testing is also used to guide treatment plan for chronic lung conditions. E.g. asthma, COPD, bronchitis etc. As it can measure the progression rate and level of the damage.
Who can Perform Spirometry testing?
Spirometry testing is performed by trained healthcare professionals with expertise in respiratory diagnostics.
| Professional | Role in Spirometry Testing |
| General Practitioners (GPs) | GPs order spirometry, especially in primary care settings. To diagnose or monitor lung conditions. |
| Respiratory Therapists | Specially trained in lung function testing. They interpret the results and guide patients during the procedure. |
| Nurses | Many nurses in primary care clinics are trained to perform spirometry. Especially in routine checks. |
| Pulmonologists | These lung specialists often use spirometry testing in hospitals. Or specialty clinics for complex cases. |
| Technicians in Respiratory Labs | In advanced settings, spirometry is conducted by technicians. They are trained in operating spirometers. |
Let’s find out its indications in detail.
Indications for Spirometry
Doctors recommend performing spirometry when you present with symptoms like:
- Shortness of breath
- Wheezing
- Cough
- Reduced lung capacity
It has several uses and benefits such as:
- Diagnosing respiratory conditions
- Monitoring the effectiveness of treatments for lung conditions
- Measuring your lung capacity
- Assessing lung function before major surgeries
- Ruling out respiratory risks after surgeries
- Identifying occupational lung diseases (by exposure to irritants like dust, chemicals, or fumes).
If you are struggling with persistent breathing problems. Spirometry is safe procedure that can help you understand and improve your condition.
Diseases Diagnosed with Spirometry Testing
If we talk about specific conditions being diagnosed and managed with Spirometry testing. It will include:
| Condition | How Spirometry Helps |
| Asthma | Spirometry helps detect airway obstruction or inflammation. And measure improvement with medications. |
| Chronic Obstructive Pulmonary Disease (COPD) | It evaluates airflow limitation. A hallmark feature of COPD. And monitors disease progression and treatment efficacy. |
| Pulmonary Fibrosis | The test identifies restrictive lung patterns and reduced lung elasticity. (fibrotic changes). |
| Chronic Bronchitis | Spirometry testing measures persistent airflow obstruction. Due to long-term mucus production. |
| Emphysema | Spirometry reveals airflow limitation caused by damage to the air sacs. |
| Atelectasis | It identifies reduced lung volume due to collapsed alveoli. And incomplete lung expansion. |
| Cystic Fibrosis | It assesses lung function in this genetic condition. By measuring the impact of thick mucus on airway obstruction. |
| Lung Cancer | It detects reduced lung capacity and airflow issues caused by tumours. |
| Occupational Lung Diseases | It identifies breathing limitations caused by long-term exposure. To dust, chemicals, or environmental pollutants. |
| Restrictive Lung Diseases | Spirometry measures reduced lung volumes and identifies underlying conditions. Like sarcoidosis or scoliosis. |
Moreover, spirometry can also be used in routine pulmonary function testing. To detect early changes in lung function and make timely intervention possible.
Procedure of Spirometry
Spirometry uses a machine called a spirometer. Which consists of a tube connected to a screen. When you blow into it, the device captures all the data about your breathing. E.g. speed and volume of air you exhale. Producing a graph called a spirogram. This graph is analysed to assess your lung health.
You will go through the following steps in the procedure.
- You will be seated comfortably. And a nose clip will be applied for accurate measurement.
- You will breathe into the spirometer through a sterile mouthpiece.
- The test is repeated several times to get accurate and consistent results.
It will show your pulmonary health in the form of multiple parameters. Details of which are given below. Performing spirometry is straightforward and non-invasive. These qualities make it accessible and easy for patients.
Tests, Normal Values, & Their Significance
Spirometry test measures the important respiratory parameters including:
| Parameter | Normal Value | Interpretation | Significance |
| FVC (Forced Vital Capacity) | 80%-120% of predicted value | Measures the maximum air volume you can exhale. | Lower FVC indicates restrictive lung diseases |
| FEV1 (Forced Expiratory Volume in 1 Second) | >75% of predicted value | It determines the total air volume exhaled in one second. | Lower FEV1 shows obstructive lung diseases |
| FEV1/FVC Ratio | >0.70 | A percentage showing your lung capacity | Lower value means something is blocking your airways |
Abnormal results will lead to more investigations or treatment adjustments.
Further Investigations:
If your results of the spirometry test fall into the “abnormal” category. The doctor will plan the further diagnostic tests for confirmation of findings. They include:
- Chest X-rays
- Sinus X-rays
- Blood tests
These tests will confirm the diagnosis and lead the treatment process further. The diagnosis can be of obstructive conditions like asthma or COPD. Restrictive diseases, such as interstitial pulmonary fibrosis. Or any other milder lung problem.
Is the Spirometry Test Painful?
A common concern we receive is whether the spirometry test is painful.
Don’t worry. The procedure is entirely painless. However, there is a slight possibility of feeling:
- Temporary dizziness or fatigue due to repeated deep breathing
- Slight discomfort in individuals with respiratory distress
But these signs are temporary and resolve quickly. However, people with recent surgeries or unstable cardiac conditions should inform their doctor beforehand.
At Main Street Medical Centre. Our experienced healthcare professionals guide you through every step. Providing you comfort and confidence during your procedure.
Tips to Prepare for a Spirometry Test
Preparing well for your spirometry test ensures accurate results. Follow these simple tips:
- Avoid heavy meals 2 hours before test. As a full stomach can restrict your breathing.
- Refrain from smoking and alcohol for at least 24 hours before the test.
- Follow your doctor’s instructions about pausing the bronchodilators or other inhalers.
- Wear comfortable clothing and loose garments to make deep breathing easier.
- Avoid any heavy exercise at least 30 minutes before the test.

Takeaways:
Spirometry is a vital tool in diagnosing and managing respiratory health. It is used in identifying problems in your lungs. And also, for managing chronic conditions like asthma by monitoring the treatment efficacy.
With minimal risks and a straightforward procedure. It is an essential step toward better respiratory care. Understanding spirometry procedure will make you better prepared for it. And ensure accurate diagnosis of your problem.
