Pulmonary function tests
Spirometry is a widely used pulmonary function test for assessing lung volume and possible obstructions (flow problems) in the airways. During this test, forced inhalation and exhalation are performed, at maximum depth and speed. Spirometry allows to detect decrease in lung function that accompanies various pulmonological (i.e. lung) diseases. The test is useful for diagnosing several common lung diseases, such as chronic obstructive pulmonary disease (COPD) and asthma, and for monitoring their progression and treatment.
