Kune mhando mbiri dze ooxygenmajenareta anowanikwa pamusika:hutano hwehutano oksijenijenareta kutiinonyanya kushandiswa kune hutanouyehaigone kutamba mhedzisiro yeokisijeni kurapwa; zvokurapa okisijeni jenareta izvo zvinodakusanganaingzvinodiwa nenyikauye naizvozvoinogona kusangana neokisijeni kurapwa zvinodiwa zvevamwe varwere.

Maererano neGeneral Specification for MedicalOoxygenJenereta neMolecular Sieve,oksijeniis inogadzirwa neiyo molecular sieve variable pressure adsorption process uchishandisa mweya seyakabikwa.Iyo oxygen concentration yetheoksijeniyakagadzirwairi 90% ~ 96% (V/V), uye zvikamu zvasara zvinonyanya argon uye nitrogen.

Tiye litre yeokisijeni jenareta zvinorevahuwandu hwe90% okisijeni yekuisa gasi inogadzirwa paminiti.Fkana semuenzaniso, okisijeni ye5Ljenaretainogona kuburitsa 5L ye90% okisijeni yekumisikidza gasi paminiti, uye kana iwe uchifanira kubudisa yakawanda kupfuura iyi vhoriyamu yegesi, zvinozotungamira mukusakwana kweokisijeni.

Nekudaro, kunyangwe huwandu hweokisijeni hweiyo inobuda gasi iri 90%,iweinofemawo chikamu chemhepo yakajairika ine oxygen concentration ye20.8% kana uchifemaingoksijeni.Naizvozvo, thechaiyo inhaled oxygen concentration inogona kungove inenge 30%.Maererano nechiyero chekuenderera mberi kwe1 ~ 2L / min okisijeni kuyerera kwevarwere vane chirwere chisingaperi chepulmonary chirwere, iyo chaiyo inhaled oxygen concentration yekugara kwenguva refu kumba okisijeni kurapwa kwechirwere chinobstructive pulmonary chirwere chinenge 25% ~ 29%.

If urikutsvaga kwakanyatsojeka uye kunoshanda kweokisijeni kurapwa,high-flow nasal cannula (HFNC) kurapwaisarudzo yakakwana.

HFNC parizvino ndiyo yakakwanauyeinodiwa oxygen therapy modhipakati pezvakasiyanazvokurapa oxygen kubudisazvirongwa, kunyange izviyekare okisijeni therapy nzira yakatadza kuwana kiriniki application mumazuva ekutanga nekuti haina kunyatsogadzirisa matambudziko ekunyorova nekudziya.. Yakabatana nekureruka kwayo uye nyore, inoda chete kudzidziswa kuri nyore kushandisa, uyesaizvozvoiri kuwedzera kushandiswa kukiriniki.Asi mukurudambudziko nderekuti inodhura uye inogonachetekushandiswa muzvipatara,uyepachine rwendo rurefu rwekufamba kuti rikwanise kusimudzirwa zvakanyanya kumhuri.

HFNCinogona kuunza zvikomborero zviviri zvinoteveravarwere.

1. Chaiyo chaiyo inhalation oxygen concentration. Iyo yakanyanya-kuyerera yekufema humidification therapy chiridzwa pachayo ichasanganisa iyo okisijeni inobuda kubva mujenareta yeokisijeni nemhepo kuenda kune yakagadzika okisijeni, uye wozoibudisira kumurwere pamwero wekuyerera wakakwira kupfuura peak yekufemerwa kwevanhu, kudzivirira mushandisi kufema. mhepo yakajairika kukanganisa iyo oxygen concentration,uye kutongaiyo chaiyo inhalation oxygen concentration chaiyoy.

2. Kuvandudza nzira yekufema uye kukurudzira kubuda kwesputum. HFNC inopa kuyerera kwemhepo-okisijeni musanganiswa ine tembiricha isingachinji uye hunyoro, inoenderana nekupisa kwegasi uye hunyoro hwenzira yemhepo munzvimbo yakajairika yemuviri uye inovandudza basa reiyo airway mucus cilia system.
