Incazelo emfushane:

I-UBREATH inikeza usayizi wamalitha amathathu ukuze kuhlangatshezwane nezindinganiso zomhlaba wonke kanye nezidingo zemishini ye-spirometry. Ku-“Standardisation of spirometry,” i-American Thoracic Society kanye ne-European Respiratory Society batusa okulandelayo: Ngokuphathelene nokunemba kwevolumu, ukuhlolwa kokulinganisa kumele kwenziwe okungenani nsuku zonke, kusetshenziswa isirinji engu-3-L ekhishwe okungenani izikhathi ezintathu ukuze kunikezwe ukugeleza okuhlukahlukene okuhluka phakathi kuka-0.5 no-12 L•s-1 (nezikhathi zomjovo ezingu-3-L ezingama-~6 s kanye no-<0.5 s).
