About Pulmonary Function Tests (PFTs)
Pulmonary function testing is a simple, noninvasive and reproducible procedure which is carried out to diagnose Obstructive (Asthma, COPD, etc.) and Restrictive Lung disorders (Interstitial Fibrosis, etc.) and asses their severity. Here the patient is asked to ‘Blow’ into a computerized machine to assess lung functions.
We have the latest computerized pulmonary function laboratory which provides routine pulmonary diagnostic tests and many more specialized procedures.
Tests available in our unit:
- Spirometry (Adults and Children)
- Maximum Ventilation Volume (MVV)
- Lung Volume and Sub-divisions, including TLC, RV and FRC by Multibreath Helium Dilution Method
- Single Breath Diffusion Capacity of Lungs (DLCO-He),
- Pre and Post Bronchodilator comparison
- Bed side spirometry, for patients admitted to nursing homes
Frequently Asked Questions
Lung function tests are a series of noninvasive procedures that measure how your lungs function. They provide information about air flow in and out of your lungs.
Doctors use these tests to diagnose conditions such as allergies, chronic lung conditions and other diseases. In addition, your doctor may use these tests to evaluate treatment for conditions such as asthma and chronic obstructive pulmonary disease (COPD), as well as assess the health of your lungs before you undergo surgery.
Before testing begins, you’ll be asked to loosen tight clothing and remove jewelry or other objects that may interfere with testing.
Tests may be performed sitting or standing, depending on your doctor’s instructions.
Generally, during testing you can expect:You’ll wear a nose clip to ensure you breathe through your mouth, rather than your nose.
You’ll be given a sterile mouthpiece for the spirometer and asked to perform a variety of breathing exercises, such as deep and shallow breathing, or slow and fast breathing. Depending on your specific testing, you may be asked to repeat breathing exercises several times.
You may be given a bronchodilator medication (to open airways) during testing and asked to repeat breathing exercises after the medication has taken effect.
Because tests are noninvasive, it’s safe for most people.
Your doctor will receive a copy of the results 5 min after the test.
