Understanding the Lung Breathing Test and Its Purpose

Pulmonary Function Tests (PFTs) measure how well your lungs work. They help doctors diagnose and manage respiratory conditions. These tests are key for checking lung health and finding issues early.
When you take a PFT, you’re learning about your lung health. PFTs are non-invasive. They give important info about your lung function. This helps doctors make better decisions for your care.
Why Doctors Order a PFT Exam
Doctors order PFT exams for many reasons. They want to diagnose and monitor lung conditions. If you have symptoms or risk factors for lung diseases like COPD, pulmonary fibrosis, or asthma, a PFT might be recommended.
Some reasons for a PFT include:
- Diagnosing lung diseases such as asthma or COPD
- Monitoring the progression of lung disease
- Evaluating the effectiveness of treatments
- Assessing lung function before surgery
Common Conditions Diagnosed Through Lung Function Testing
Lung function testing is key for diagnosing and managing respiratory conditions. Some common conditions diagnosed through PFTs include:
- Chronic Obstructive Pulmonary Disease (COPD): A progressive lung disease that makes it hard to breathe.
- Asthma: A condition that causes inflammation and constriction of the airways.
- Pulmonary Fibrosis: A condition where lung tissue becomes scarred, leading to breathing difficulties.
Understanding your PFT results helps your healthcare provider create a treatment plan. This plan is tailored to manage your condition effectively.
What Is Involved in a Pulmonary Function Test

Getting ready for a PFT involves several important steps. These steps help get accurate results. Knowing what to expect can make you feel more at ease.
Preparing for Your PFT Lab Test
You’ll get specific instructions before your test. These might include what medications to take or not, what to wear, and what to eat. Following these instructions is key. You might need to stop certain meds or avoid hard activities before the test. Wearing loose, comfy clothes helps too.
The Step-by-Step Procedure During the Exam
On test day, you’ll go to a PFT lab. A trained technician will do the test. You’ll breathe into a mouthpiece connected to a machine.
You’ll be asked to breathe deeply, blow air hard, or breathe normally. You might need to do some parts a few times. The whole thing is designed to be easy and comfortable. The technician will help you through it all.
Interpreting Results and Possible Side Effects
Understanding your Pulmonary Function Test results is key to knowing your lung health. Your doctor will look at the test data to see how your lungs are doing.
Understanding Normal Versus Abnormal PFT Values
PFT results are compared to standard values based on age, sex, height, and ethnicity. Normal values are usually above 80% of the predicted value. If your results are below this, it might mean your lungs are not working right.
For some, z scores are used to check results that are close to or below expected ranges. Z scores help decide if more tests are needed.
| PFT Parameter | Normal Value | Abnormal Value |
| FEV1/FVC Ratio | > 70% | |
| FEV1 | > 80% predicted | |
| FVC | > 80% predicted |
Common Side Effects of Pulmonary Function Tests
PFTs are usually safe, but some people might feel dizzy, have trouble breathing, or cough after the test. These feelings usually go away quickly.
When to Seek Medical Follow-up After Testing
If you keep feeling bad after a PFT, like you can’t breathe well, have chest pain, or cough a lot, you should get medical help. Your doctor can tell you what to do next based on your test results and how you’re feeling.
Knowing your PFT results and any side effects helps you take care of your lung health better.
