Spirometry is a common office test used to determine
how well your lungs work.
Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. Spirometry may also be used periodically to monitor your lung condition and check whether a treatment for a chronic lung condition is helping you breathe better.
What you can expect?
A spirometry test requires you to breathe into a tube attached to a machine called a spirometer. Your doctor may give you an inhaled medication to open your lungs (bronchodilator) after the initial round of tests and then another set of measurements is taken. Your doctor then can compare the results of the two measurements to see whether the bronchodilator improved your airflow.
