Spirometry

Spirometry is a medical test that measures lung function by assessing how much air a person can inhale and exhale. It is a non-invasive, painless test that can be used to diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and lung fibrosis. The results of a spirometry test can provide important information about a person's lung health, including lung volume, airflow, and the presence of any blockages or abnormalities.

To perform a spirometry test, a person will typically be asked to sit in a chair and wear a nose clip to prevent air from escaping through the nose. They will then be instructed to take a deep breath and exhale as forcefully and completely as possible into a mouthpiece connected to a spirometer. The spirometer will measure the volume of air exhaled and the speed at which it was exhaled, producing a graph called a spirogram. The test may be repeated several times to ensure accurate results.

Spirometry is a valuable tool in the diagnosis and management of respiratory conditions. It is a safe, non-invasive test that can be performed in a doctor's office or clinic. If you are experiencing symptoms of a respiratory condition or have been diagnosed with one, your doctor may recommend a spirometry test to assess your lung function and determine the best course of treatment. Regular spirometry tests can also be used to monitor the progression of a respiratory condition and adjust treatment as needed.
