Inkcazo emfutshane:

I-UBREATH inikezela ngobukhulu obuziilitha ezi-3 ukuhlangabezana nemigangatho yamazwe ngamazwe kunye neemfuno zezixhobo ze-spirometry. Kwi-“Standardisation of spirometry,” i-American Thoracic Society kunye ne-European Respiratory Society zicebisa oku kulandelayo: Ngokuphathelele ukuchaneka komthamo, ukuhlolwa kokulinganisa kufuneka kwenziwe ubuncinci yonke imihla, kusetyenziswa isirinji ye-3-L ekhutshiwe ubuncinci kathathu ukunika uluhlu lokuhamba oluhluka phakathi kwe-0.5 kunye ne-12 L•s-1 (ngamaxesha okujova e-3-L angama-~6 s kunye ne-<0.5 s).
