Lung Function Tests
(Análisis de la función pulmonar)
Lung (or pulmonary) function tests are a variety of tests that measure how well a person breathes. They can be used to help diagnose asthma, as well as to assess the severity of a person's asthma and how effectively it's being managed. One example of a lung function test is called spirometry, which involves breathing into a device that records how much and how quickly air can be breathed out following a deep breath in.
