Lung Function Tests
(En español: Análisis de la función pulmonar)
Say: lung funk-shun tests
How well do your lungs function? In other words, how well are you breathing? There are several tests that can help your doctor answer that question. For one of them, called spirometry, you take a breath and then blow the air out as fast and long as you can. These tests can help a doctor find out if someone has asthma.
