Oxygen therapy inzira yakajairika mukurapa kwemazuva ano, uye ndiyo nzira yekutanga yekurapa hypoxemia.Kazhinji kiriniki yeokisijeni therapy nzira dzinosanganisira nasal catheter okisijeni, nyore mask okisijeni, Venturi mask okisijeni, etc. Zvakakosha kunzwisisa maitiro ekushanda emhando dzakasiyana-siyana dzeokisijeni therapy kuti uone kurapwa kwakakodzera uye kudzivisa matambudziko.

Chiratidzo chinowanzoonekwa cheokisijeni therapy ndeye acute kana kusingaperi hypoxia, iyo inogona kukonzerwa nehutachiona hwemapapu, chirwere chisingaperi chechirwere chemapapu (COPD), congestive heart failure, pulmonary embolism, kana kuvhunduka nekukuvara kwakanyanya kwemapapu.Oxygen therapy inobatsira kune vakapiswa, carbon monoxide kana cyanide poisoning, gas embolism, kana zvimwe zvirwere.Iko hakuna zvachose contraindication yeokisijeni therapy.

Nasal Cannula

Catheter yemhino ichubhu inochinjika ine zvibodzwa zviviri zvakapfava zvinopinzwa mumhino dzemurwere.Hairemi uye inogona kushandiswa muzvipatara, mudzimba dzevarwere kana kumwewo.Iyo chubhu inowanzoputirwa kuseri kwenzeve yemurwere uye inoiswa pamberi pemutsipa, uye inotsvedza bhandi yemhino inogona kugadziriswa kuti ibate panzvimbo.Kubatsira kukuru kwekatheta yemhino ndeyekuti murwere akasununguka uye anogona kutaura, kunwa uye kudya zviri nyore necatheter yemhino.

Kana okisijeni yaunzwa kuburikidza nekatheta yemhino, mhepo yakatenderedza inosanganiswa neokisijeni muzvikamu zvakasiyana.Kazhinji, pakuwedzera kwe1 L / miniti mukuyerera kweokisijeni, iyo inhaled oxygen concentration (FiO2) inowedzera ne4% kana ichienzaniswa nemhepo yakajairika.Zvisinei, kuwedzera kufefetedza kweminiti, ndiko kuti, kuwanda kwemweya wakafemeswa kana kubuditswa muminiti imwe, kana kufema nemuromo, kunogona kuderedza oksijeni, nokudaro kuderedza chikamu cheokisijeni inofemerwa.Kunyangwe iyo yakanyanya mwero wekuburitswa kweokisijeni kuburikidza nenasal catheter iri 6 L/min, kuderera kweokisijeni kuyerera hakuwanzo kukonzera kuoma kwemhino uye kusagadzikana.

Nzira dzekuburitsa okisijeni yakaderera, senge nasal catheterization, haina kunyatso fungidziro yeFiO2, kunyanya kana ichienzaniswa nekuendeswa kweokisijeni kuburikidza netracheal intubation ventilator.Kana huwandu hwegasi hunofemerwa hunopfuura kuyerera kweokisijeni (sekune varwere vane maminetsi emhepo inofefetera), murwere anofema mhepo yakawanda yemhepo, iyo inoderedza FiO2.

Oxygen Mask

Senge catheter yemumhino, mask iri nyore inogona kupa okisijeni yekuwedzera kune varwere vanofema vega.Iyo mask yakapfava haina masaga emhepo, uye maburi madiki kumativi ese emasiki anobvumira mweya wepamhepo kupinda paunenge uchifema nekusunungura paunenge uchifema.FiO2 inotemerwa nekuyerera kweokisijeni, mask fit, uye murwere miniti yekufema.

Kazhinji, okisijeni inopiwa pamwero wekuyerera we5 L paminiti, zvichiita kuti FiO2 ye0.35 kusvika 0.6.Utsi hwemvura hunonyunguduka mumasikisi, zvichiratidza kuti murwere ari kufema, uye inokurumidza kunyangarika kana gasi idzva rikafemerwa.Kubvisa mutsara weokisijeni kana kuderedza kuyerera kweokisijeni kunogona kuita kuti murwere afeme oksijeni isina kukwana uye kufema zvakare exhaled carbon dioxide.Matambudziko aya anofanira kugadziriswa nekukasika.Vamwe varwere vanogona kuwana mask ichisunga.

Kwete-kufemazve Mask

A asingadzokorori kufema masiki ndiyo yakagadziridzwa masikisi ine okisijeni reservoir, cheki chevhavha inobvumira okisijeni kuyerera ichibva mudura panguva yekufema, asi inovhara dura pamhepo uye inobvumira dhamu kuti rizadzwe ne100% okisijeni.Hapana kudzokorora kufema mask kunogona kuita kuti FiO2 isvike 0.6 ~ 0.9.

Masikisi ekufema asingadzokorore anogona kunge aine mavharuvhu epadivi rimwe chete kana maviri anovhara pakufema kudzivirira kufemerwa kwemhepo yakatenderedza.Vhura pakufemesa kuti uderedze kufema kwegasi rakaburitswa uye kuderedza njodzi yeyakakwira carbonic acid
