What is Pulmonary Function Test (PFT)? Procedure, Uses & Benefits
What is a Pulmonary Function Test (PFT)?
A Pulmonary Function Test (PFT) is a group of non-invasive tests used to measure how well your lungs are working. It helps evaluate lung capacity, airflow, and oxygen exchange, making it an essential test for diagnosing respiratory conditions.
Why is a PFT Test Done?
A PFT test is recommended to diagnose and monitor lung diseases. It is commonly used for:
- Asthma diagnosis
- COPD evaluation
- Lung infection assessment
- Pre-surgery lung check
- Monitoring chronic lung conditions
Types of Pulmonary Function Tests
There are different types of tests included in PFT:
1. Spirometry
Measures airflow and helps detect conditions like asthma and COPD.
2. Diffusion Capacity (DLCO)
Evaluates how well oxygen passes from lungs into blood.
3. Lung Volume Test
Measures total lung capacity and air retention.
PFT Procedure – What to Expect?
The PFT test is simple and painless:
- You will be asked to breathe into a mouthpiece
- Follow instructions to inhale and exhale deeply
- Test is repeated for accuracy
- Results are recorded digitally
The entire process takes around 15–30 minutes.
What Do PFT Results Show?
PFT results help doctors understand:
- Lung capacity
- Airflow obstruction
- Oxygen exchange efficiency
These results are important for diagnosing and managing lung diseases effectively.
