Pulmonary Function Test

About the test

Pulmonary Function test is a group of tests conducted to diagnose the functioning of the respiratory system. It includes the test which measures the working of lungs as well as its effectiveness in carrying oxygen to the rest of the body. The test measures lung capacity, volume, gas exchange and rate of flow of oxygen in the lungs. The result helps healthcare provider to diagnose problems in the lungs and decide the required treatment. The test is non-invasive in nature and the test includes- Spirometry, Plethysmography and Diffusion Capacity test. These tests help measure different functioning of the lungs.

The procedure for the process is as follows:

  • Any object such as jewelry on the body which may interfere with the procedure should be removed.
  • It is advised to wear loose clothing.
  • There is no issue with dentures and could be worn in the procedure.

  • A tight seal should be formed over the mouthpiece with mouth and the individual will be asked to inhale and exhale in several ways.
  • The individual will be watched in the procedure for trouble breathing, dizziness or other issues.
  • A bronchodilator will be provided after certain tests and the test will be repeated a few minutes later.
