Does pulmonary function test show COPD?
The most effective and common method for diagnosing COPD is spirometry. It’s also known as a pulmonary function test or PFT. This easy, painless test measures lung function and capacity. To perform this test, you’ll exhale as forcefully as possible into a tube connected to the spirometer, a small machine.
What are 3 physical assessment findings signs that are associated with COPD?
