Ukuphazamiseka okungafaniyo kunye nokukhuseleka kwezifo ze-Lung nge-FEV1 / FVC
Ekuhloliseni nasekuphatheni izifo zomngcipheko eziphazamisayo ezifana nesifo esingapheliyo se-pulmonary pulmonary (COPD), oogqirha bahlala basebenzisa iimvavanyo ezahlukahlukeneyo ukuqonda ubunzima besifo. Enye yale mvavanyo ibizwa ngokuba yi-spirometry , apho imilinganiselo eyahlukeneyo yomsebenzi wamaphaphu ibalwa.
Ukulinganisa i-FEV1 / FVC
Omnye ugqirha obaluleke kakhulu oogqirha basebenzise ukujonga umsebenzi wamaphaphu ngumlinganiselo wokuvotelwa komqulu kwisibini enye ( FEV1 ) ngaphaya komthamo obalulekileyo wokunyanzeliswa ( FVC ), owaziwa ngokuba yi-Tiffeneau-Pinelli index.
Lo ngumlinganiselo wenani lomoya okhuphelwa ngamandla kwisibini enye kuthelekiswa nomlinganiselo opheleleyo womoya onokuphefumlelwa ngamandla ngomoya ophelileyo.
Isixa somoya okhuphayo kwisibini esinye sibhaliweyo ngokunjalo kwisixa esiphezulu somoya okwazi ukukhupha. Ngokusekelwe kwinani le-FVC elibalwe ubuncinane nobukhulu bakho, umlinganiselo walezi zixabiso 2 uvavanywa. Ngokuqhelekileyo, ixabiso lembini lilingana. Ukuba i-FVC iyancipha, umlinganiselo ubujongwa ngokuthe ngqo.
I-FVC eyancitshiswe ngeProportional FEV1 / FVC I-Ratio-Restrictive Pattern
Ukuba i-FVC yakho iyancipha kodwa umlinganiselo we-FEV1 / FVC uyinto eqhelekileyo, oku kubonisa iphethini engqongqo. Izifo zomngcipheko ezithintekayo zingaba ziindawo ezonakaliswe ngayo izicubu zamaphaphu, okanye xa zilungiswa ukuba umntu akakwazi ukuphefumula ngokuqhelekileyo njengesiqhelo. Ezinye imizekelo ziquka:
- I-pulmonary fibrosis, efana ne- idiopathic pulmonary fibrosis , ukunqanda imiphunga yezathu elingaqinisekanga.
- Ukutshatyalaliswa kwesifuba njengesikolo se-scliliosis okanye udonga lwesifuba
- Utyando lomhlaza womlenze, olufana ne-lobectomy okanye i-pneumonectomy
- Izifo kunye nezifo ezivuthayo ezifana ne-pneumonia, isifo sofuba, i-sarcoidosis, i-silicosis, kunye ne-asbestosis
- Iingxaki ze-neurological ezifana ne- ALS
- Ukutshatyalaliswa kwamanzi, okwenzekayo kummandla phakathi kweenjini ezijikeleze imiphunga
- Ama-Ascites, i-buildup yomthamo esiswini esiswini ngenxa yesifo sesibindi okanye umdlavuza kwisisu esisenokubangela ukuba umzekelo wesithintelo ngokunciphisa ukukwazi ukuthatha umoya.
Ukunciphisa i-FVC kunye ne-FEV1 / FVC ye-Ratio-Obstructive Pattern Pattern
Ukuba i-FVC yakho iyancipha kwaye umlinganiselo wakho we-FEV1 / FVC uyancipha, oku kuhambelana nesimo sokuphazamisa isifo seemiphunga njenge-asthma kunye ne-COPD. Ngokuqhelekileyo, le ngxaki ifikeleleka ukuba i-FEV1 / FVC ingaphantsi okanye ilingana nama-70 ukuya kuma-80 ekhulwini abantu abadala, kunye ne-85 ekhulwini kubantwana. Ukulimala kwi-airways kunye / okanye ukunyanzeliswa kwe-airways kubonisa imiqathango efana nale:
- Isifuba
- Izifo zokuphefumula ezingapheliyo ezifana ne-bronchitis engapheliyo, i-emphysema kunye ne-bronchiectasis
- Bronchiolitis
Amanyathelo alandelayo
Ukuba umzekelo onqandekileyo ugcinwa, oogqirha baya kuthi banconywe ukuhlola iimvavanyo zomsebenzi wepulmoni ezizeleyo ukuze ziqhubeke zibonisa isifo sakho somphunga. Ukuba umzekelo obangelwayo ufunyenwe, isinyathelo esilandelayo ngokuqhelekileyo ukunyusa unyango nge- bronchodilator , unyango olunceda ukunciphisa ukunyuka kwe-airways nokuphinda uvavanyo.
Ukuba uphathwe isifo sokuphazamiseka kwesifo semiphunga, ugqirha wakho uya kubeka iliso kwinkqubela yakho usebenzisa u-FEV1 / FVC isilinganiso salo. Ukuba umlinganiselo uphuthukisiwe ne-bronchodilator, oko kuthetha ukuba ukukhuseleka okungenani "kuguqulwa". Oku kubonakala ngeemeko ezinjenge-asthma.
Ukuba ngaba umlinganiselo awuphuculanga nge-bronchodilator, unokusenokungenakwenzeka, njengeCOPD.
