What is a PFT test, and how does it help evaluate lung health? - #14734
I recently learned about a PFT test, and I’m curious about how it works and why it’s used for lung health assessment. I know it stands for pulmonary function test, but I don’t fully understand how it measures lung function. What is a PFT test, and how does it evaluate lung function? I read that it measures things like lung volume, airflow, and gas exchange—does that mean it helps doctors assess conditions like asthma, COPD, or pulmonary fibrosis? Also, how is the test performed, and is it uncomfortable? I also want to understand what the results of a PFT test mean. What happens if a person has abnormal results, and how is it treated? Are there natural ways to improve lung health that can support PFT test results, like exercise or breathing techniques? If anyone has had a PFT test, what was the reason, and how did it help with diagnosis? Were any lifestyle changes recommended based on the results?
