Pulmonary Function Test

Pulmonary function tests (PFT), also known as a Spirometry measures lung function; specifically the amount and speed of air that can be inhaled and exhaled. PFT’s are helpful in assisting breathing patterns that identify conditions such as asthma, pulmonary fibrosis, and COPD.

The purpose, procedure, discomfort, and risks of the test will vary.

• Spirometry measures the rate of air flow and estimates lung size. For this test, you will breathe multiple times, with regular and maximal effort, through a tube that is connected to a computer. Some people feel lightheaded or tired from the required breathing effort.
• Pulse oximetry estimates oxygen levels in your blood. For this test, a probe will be placed on your finger or another skin surface such as your ear. It causes no pain and has few or no risks.

Many times, a pulmonary function test is done along with a respirator fit test. The respirator fit testing ensures the right mask fit and model for the employee, the pulmonary function test actually gauges the employee’s lung health. Most often, employers use this test to develop a baseline to compare against future tests to identify possible lung issues before clinically evident.

Having this established baseline provides good protection when evaluating the cause of worker’s compensation claims. The baseline also helps to ensure employees have the adequate protection necessary to perform their job.
