In tutorial 4, we provide an overview of the spirometer and the disposables that are used during testing, as well as how to check that the spirometer is working properly.

Key messages:

• Most spirometers are flow-measuring devices. Get to know the type of spirometer you have, and some potential errors to look out for.
• Syringe verification is a quality assurance that checks whether the spirometer is working properly. Syringe verification should be performed before every spirometry session.
• Follow local infection control procedures and manufacturer’s guidance.
