Pulmonary Function Testing (PFT) is a group of tests that assess how well your lungs are functioning. These tests measure lung volume, capacity, rates of flow, and gas exchange to help diagnose and manage respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, and more. PFT provides essential information about lung health, allowing for better treatment decisions.
At Dr. Singal's Comprehensive Care Clinic, Dr. Namrata Singal, Senior Consultant Pulmonologist, offers comprehensive PFT services to evaluate lung function and guide treatment strategies for various pulmonary conditions.
During the PFT, you will be asked to breathe into a spirometer or other testing devices. You may be instructed to take deep breaths, breathe out forcefully, or hold your breath at certain times. The tests are non-invasive and typically take about 30 to 60 minutes to complete.
Yes, certain preparations may be needed, such as avoiding heavy meals, smoking, and some medications (e.g., bronchodilators) before the test. Dr. Singal will provide specific instructions based on your individual circumstances.
PFT is generally safe and non-invasive, with minimal risks. Some patients may experience mild discomfort or shortness of breath during the tests, but these symptoms usually resolve quickly. If you have any concerns, discuss them with Dr. Singal prior to the test.
Results are analyzed by comparing your lung function measurements to normal values based on age, sex, height, and ethnicity. Dr. Singal will explain the results to you, discuss any abnormalities, and recommend appropriate treatment options if necessary.
