Background: Spirometry has become an essential tool for general practices to diagnose and monitor chronic airways diseases, but very little is known about the performance of the spirometry equipment that is being used in general practice settings. The use of invalid spirometry equipment may have consequences on disease diagnosis and management of patients.
Objectives: To establish the accuracy and precision of desktop spirometers that are routinely used in general practices.
