What is spirometry?

It is a method of measuring external respiration. It is one of the main diagnostic methods for assessing lung function. Spirometry is prescribed in order to identify lung capacity and the ability of the bronchi to let the air through during inspiration and expiration.

What to expect during the procedure?

The test is carried out using a spirometer. The patient is seated next to the device. A special clip is placed on the nose to prevent the air from escaping through the nose. The patient breathes through the mouth into a special tube, following the doctor’s instructions. A special single-use mouthpiece is placed onto the tube for hygienic purposes.

The spirometer processes the data automatically, so the results are available within 5-10 minutes after the test. The doctor analyzes the data and identifies the disorders of external respiration.
