Ukuhlolwa kwe-FeNO ukuhlolwa okungahlaseli okukala inani legesi ye-nitric oxide emphefumulweni womuntu. I-nitric oxide igesi ekhiqizwa amaseli asophahleni lwendlela yomoya futhi iwuphawu olubalulekile lokuvuvukala kwendlela yomoya.
Yini ehlonzwa ukuhlolwa kwe-FeNO?
Lokhu kuhlolwa kuyasiza ekuxilongeni i-asthma lapho imiphumela yokuhlolwa kwe-spirometry ingacacile noma ibonisa ukuxilongwa okulinganiselwe. Ukuhlolwa kwe-FeNO kungabona nokuvuvukala emigwaqweni yomoya engezansi, kufaka phakathi ama-bronchioles, futhi kuqaphe ukuqhubeka kokwelashwa. Lolu hlobo lokuvuvukala lubangelwa amazinga aphezulu kunavamile amaseli amhlophe egazi (ama-eosinophil) emaphashini akho. Ngokuvamile azobizwa ukuze avikele amagciwane okuphefumula, kodwa ku-asthma ye-allergy le mpendulo iyandiswa futhi ayilawulwa okuholela ekuvuvukeni okungapheli.
Ukuhlolwa kwe-FeNO kwenziwa kanjani?
Phakathi nalokhu kuhlolwa kwamaphaphu, isiguli sikhipha umoya singene kudivayisi elinganisa ukugcwala kwe-nitric oxide emoyeni waso. Ukuhlolwa kuthatha imizuzu embalwa kuphela ukwenza futhi kulula futhi akubuhlungu. Lapho imiphumela yokuhlolwa ihlaziywa, amazinga aphezulu e-nitric oxide abonisa ukuba khona kwe-asthma. Imiphumela ingasetshenziswa futhi ukuhlukanisa phakathi kwezinhlobo ezahlukene zokuvuvukala komoya, njengoba amazinga aphezulu e-FeNO ehlotshaniswa nezimo ezifaka phakathi i-allergy rhinitis, i-COPD, kanye ne-cystic fibrosis. Kungabonisa ukusetshenziswa kwe-corticosteroid inhaler ukunciphisa ukuvuvukala nokuxazulula ukuvuvukala komoya. Ngokuvamile inani lezinhlayiya kufanele libe ngaphansi kwezingxenye ezingu-25 ngezigidigidi.
Yini Okufanele Ngiyigweme Ukuphuza?
Ngaphezu kokugwema konke ukudla neziphuzo ihora elilodwa ngaphambi kokuhlolwa kwakho kwe-FeNo, uhla lwezinto ezithile akufanele zidliwe ngosuku lokuhlolwa kwakho ngoba zingaphazamisa imiphumela. Lolu hlu olubanzi luhlanganisa okulandelayo:
Ngizilungiselela Kanjani Ukuhlolwa kwe-FeNo?
Ekuhlolweni kwe-FeNo sifuna ukukala inhlayiya yegesi ezwela kakhulu ngakho sizokucela ukuthi uqaphele kakhulu ngalokho okufaka emzimbeni wakho ngaphambi kokuhlolwa. Sicela ungadli ukudla noma isiphuzo ihora elilodwa ngaphambi kokuhlolwa. Sizokucela futhi ukuthi ungadli ukudla neziphuzo ezithile ngosuku lokuhlolwa kwakho, njengoba kungashintsha amazinga ale gesi ekuphefumuleni kwakho.
