Hariho ubwoko bubiri bwa oxygenamashanyarazi aboneka ku isoko:ubuzima bwiza ogisijenigeneratorikoreshwa cyane cyane mubuvuzinantishobora gukina ingaruka zo kuvura ogisijeni; ubuvuzi bwa ogisijeni ibyo bisabaguhuraingibipimo ngenderwaho bijyanye n'igihugubityoirashobora guhaza abarwayi ba ogisijeni bakeneye.

Ukurikije ibisobanuro rusange byubuvuziOxygenGenerator hamweIcyuma cya molekulari,ogisijeniis byakozwe na molekile ya sivile ihindagurika ryumuvuduko wa adsorption ukoresheje umwuka nkibikoresho fatizo.Umwuka wa ogisijeni waiogisijenibyakozweni 90% ~ 96% (V / V), naho ibice bisigaye ni argon na azote.

Tlitiro yagenerator bivugaingano ya 90% ya gaze ya ogisijeni ikorwa kumunota.F.cyangwa urugero, ogisijeni ya 5LgeneratorIrashobora gutanga 5L ya 90% ya gaze ya ogisijeni yibanze kumunota, kandi niba ugomba gusohora ibirenze ubu bunini bwa gaze, bizatuma umwuka wa ogisijeni udahagije.

Nyamara, nubwo umwuka wa ogisijeni wa gaze isohoka ari 90%,woweizahumeka kandi igice cyumwuka usanzwe hamwe na ogisijeni ya 20.8% mugihe ihumekaingogisijeni.Kubwibyoumwuka wa ogisijeni uhumeka ushobora kuba hafi 30%.Ukurikije igipimo cy’umuvuduko ukabije wa 1 ~ 2L / min wa ogisijeni ku barwayi bafite indwara zidakira zifata ibihaha, ubwinshi bwa ogisijeni ihumeka y’imyororokere yo mu rugo igihe kirekire ivura indwara zidakira zifata ibihaha ni 25% ~ 29%.

If urigushakisha uburyo bunoze kandi bunoze bwo kuvura ogisijeni,high-flow izuru cannula (HFNC) ivurani amahitamo meza.

HFNC kuri ubu iruzuyenaibyifuzo bya ogisijeni yo kuvuramuri zitandukanyeubuvuzi bwa ogisijeniSisitemu, nubwo ibiuburyo bwa kera bwo kuvura ogisijeni bwananiwe kubona amavuriro muminsi yambere kuko butakemuye neza ibibazo byo gutose no gushyuha. Hamwe nuburyo bworoshye kandi bworoshye, bisaba imyitozo yoroshye yo gukoresha, kandibityoni Byinshi Byakoreshejwe Mubuvuzi.Ariko majorikibazo nuko bihenze kandi birashobokagusagukoreshwa mu bitaro,naharacyari inzira ndende kugira ngo itere imbere cyane mumiryango.

HFNCirashobora kuzana inyungu ebyiri zikurikira kuriabarwayi.

1. Guhumeka neza umwuka wa ogisijeni. Igikoresho kinini cyo kuvura ubuhumekero cyinshi ubwacyo kizavanga umwuka wa ogisijeni uva muri generator ya ogisijeni hamwe n’umwuka ugashyira umwuka wa ogisijeni, hanyuma ukawusohora ku murwayi ku kigero cyo hejuru kirenze impinga yo guhumeka abantu, birinda umukoresha guhumeka. umwuka usanzwe kugirango ugire ingaruka kuri ogisijeni,no kugenzuraguhumeka nyabyo umwuka wa ogisijeni yibanzey.

2. Kunoza inzira zo guhumeka no guteza imbere gusohoka. HFNC itanga umuvuduko mwinshi wo mu kirere-ogisijeni ivanze n'ubushyuhe n'ubushyuhe buri gihe, ibyo bikaba bihuye n'ubushyuhe bwa gaze n'ubushuhe bw'umwuka uhumeka mu buryo busanzwe bw'umubiri kandi bigateza imbere imikorere ya sisitemu yo mu kirere ya mucus cilia.
