Spirometry is a pulmonary function test that measures how much air a person can breathe out and how quickly they can do it, making it an essential tool for diagnosing and monitoring respiratory conditions like asthma and COPD. It provides objective measurements of lung function, allowing healthcare providers to assess airflow limitation, determine disease severity, and evaluate response to treatment over time.
