I-FEV1 yinani eliphakeme kakhulu lomoya ongaziqeda ngamandla ngomzuzwana owodwa. Ibuye ishintshwe kumaphesenti evamile. Isibonelo, i-FEV1 yakho ingaba ngu-80% webikezelo esekelwe ekuphakameni kwakho, isisindo, nohlanga. I-FEV1 iyimakethi yezinga lokuvimbela isifo sakho se-asthma:
- I-FEV1 engaphezulu kuka-80% okubikezelwe = evamile
- FEV1 60% kuya ku-79% okubikezelwe = Ukuvinjelwa okuncane
- FEV1 40% kuya ku-59% okubikezelwe = ukuvinjelwa okulinganiselwe
- I-FEV1 engaphansi kuka-40% okubikezelwe = ukuvinjelwa okukhulu
I-FEV1 ingenye yezinkomba ezivame ukusetshenziswa ukuhlola ukuvimbela umoya. Ibalwa ngokuzenzakalelayo phakathi nokuhlolwa komsebenzi we-spirometry noma we-pulmonary. Kubalwa ngokusebenzisa i-spirometer.
I-FEV1 isetshenziswa kanjani ku-Asthma yami
Iningi evame ukuphoqa ivolumu yokuphefumula lizokwaziswa udokotela wakho njengengxenye yokuhlolwa kokusebenza kwamapulmonary. Udokotela wakho angenza lokhu ukuze ahlole izimpawu zakho ngaphambi kokuba kutholakale ukuhlolwa kwesifo se-asthma noma ukuqapha ukulawula kwakho kwe-asthma njengengxenye yesicwangciso sakho somsebenzi we-asthma. Izimpawu ezifana nalezi ezilandelayo zingabangela udokotela wakho ukuba alawule lezi zivivinyo:
Eminyakeni edlule, indlela kuphela yokuthola ivolumu yokuphefumula kwaba yimishini ehhovisi. Ngokufika kobuchwepheshe obusha, manje kungenzeka ukuthi uthole i-FEV1 emshinini osuselwa ekhaya-okusho ukuthi wena nodokotela wakho bangasebenzisa lokhu njengengxenye yokuqapha kwe-asthma yakho ekhaya .
Lokhu kuhlolwa kuqhathaniswa nedatha oyithola ekusebenzeni ukuphakama kwezinga eliphezulu. I-meter ye-flow meter ikunika inombolo elinganisela inani lemimoya ongayiphuma emaphashini akho nge-exhalation enamandla. Uma isetshenziswe ngokuphindaphindiwe ngokuhamba kwesikhathi, ukuguqulwa kokugeleza kwakho kwezinga eliphezulu kungakuzisa ukuthi i-asthma yakho ayikho ngaphansi kokulawula okunjengokuthi ungafuna.
Amapulani amaningi we-asthma action asebenzisa ukuphakama kwe-peak njengenye yezimbangela zesenzo engxenyeni yakho. Uzonquma ukuthi ukukhishwa kwakho okungcono kunakho konke bese ubeka isenzo sakho kumaphesenti walowo nombolo. Ngakho akuyona inombolo yangempela ebalulekile kule nkinga, kodwa izinguquko ezihambelanayo ozibonayo ngokuhamba kwesikhathi.
Uma uzosebenzisa ivolumu yokuphefumula okuphoqelelwe njengengxenye yesicwangciso sakho sohlelo lokusebenza lwe-asthma uzodinga ukukhuluma nodokotela wakho mayelana nokuthi uhlobo luni lwe-spirometer yasekhaya lungase lube ngcono kuwe.Izinhlobo ezinamamodeli ahlukene anezici ezahlukene namaphuzu wamanani.
Khona-ke uzodinga ukuqapha nokurekhoda i-FEV1 yakho ngokuhamba kwesikhathi. Wena nodokotela wakho kuzodingeka ukuthi ubeke ukufundwa okukhethekile kwe-FEV1 ezindaweni zakho eziluhlaza, eziphuzi, nezibomvu zesicwangciso sokusebenza se-asthma.
