kuzuza ogisijeni (SaO2) ni ijanisha ry'ubushobozi bwa oxyhemoglobine (HbO2) ihujwe na ogisijeni mu maraso kugeza ku bushobozi bwose bwa hemoglobine (Hb, hemoglobine) ishobora guhuzwa na ogisijeni, ni ukuvuga kwibumbira hamwe kwa ogisijeni mu maraso muri maraso.ibyingenzi byingenzi bya physiologique.
Amaraso yuzuye ya ogisijeni yerekana ubuzima bwumubiri wumuntu kandi arashobora kwerekana ubuzima bwimikorere yubuhumekero bwumuntu hamwe na sisitemu yumutima.Ifite uruhare runini mu gukumira no gusuzuma indwara zabantu.Kubwibyo, gukurikirana ubwuzure bwamaraso ya ogisijeni ni ngombwa cyane.ibisobanuro bya physiologique.
Uburyo bwa Clinical non-invasive bwo gupima ubwuzure bwamaraso ya ogisijeni ni ugukoresha sensor yerekana ifoto yerekana urutoki, kandi umwuka wa ogisijeni wuzuye wamaraso ya arterial ukoreshwa mugusimbuza umwuka wa ogisijeni winyama zabantu.Kugenzura amaraso ya ogisijeni yuzuye ya arterial birashobora kandi gutwara ogisijeni kuri oxyhemoglobine mu bihaha.Irashobora kwerekana mu buryo butaziguye imikorere y'ubuhumekero y'ibihaha.Agaciro ko gupima abantu bazima kagomba kuba hejuru ya 95%, kandi gashobora kuba kari munsi yabanywa itabi.Mubisanzwe bifatwa ko munsi ya 90% ari ikimenyetso cyibyago.
Niba amaraso ya ogisijeni mu maraso agabanutse, biroroshye gutera ibimenyetso nkumunaniro no gusinzira, kubura imbaraga, no kubura kwibuka.Amaraso maremare adahagije ya ogisijeni nayo azatera ubwonko, umutima nizindi ngingo.
Ubwonko nigice cyunvikana cyane mumyanya mitsi ya hypoxia.Indwara ya hypoxia yoroheje mu bwonko izatera ibimenyetso nkumunaniro wo mumutwe, kudashobora kwibanda hamwe, no kubura kwibuka.Niba ubwonko bukomeje kubura ogisijeni, bizatera urupfu rw'uturemangingo, kandi biroroshye guhindura imikorere yizindi sisitemu, zangiza ubuzima.Niba hypoxia ikabije, cyangwa hypoxia ikaze, abantu bayobora icyerekezo no guhuza ibinyabiziga bizagenda bitakaza buhoro buhoro, kandi mubihe bikomeye, guhungabana mumitekerereze, koma, ndetse nurupfu bizabaho.
Kimwe n'ubwonko, umutima ni urugingo rukoresha ogisijeni nyinshi kandi rufite umuvuduko mwinshi.Iyo umutima ari hypoxic yoroheje, umuvuduko wumutima wiyongera mbere, umuvuduko wumutima hamwe numutima wumutima byiyongera, sisitemu yumuzunguruko yishyura ibura rya ogisijeni muri hyperdynamic, kandi icyarimwe ikabyara amaraso, ikwirakwizwa ryubwonko nubwonko. .Kwaguka guhitamo kugirango amaraso ahagije bizatera ibimenyetso nkumutima utera injyana yumutima no gutitira.Iyo umutima ukomeje hypoxia idakira, kubera kwirundanya kwa acide lactique ya subendocardial, synthesis ya ATP iragabanuka, bikaviramo kwiheba kwa myocardial, bikaviramo bradycardia, kwikuramo imburagihe, kugabanuka k'umuvuduko w'amaraso no gusohoka k'umutima, ndetse na arththmias nka fibrillation ventricular ndetse na ventricular fibrillation.asystole.Iyo umutima ufite hypoxic bikabije, bizagutera hypertrophyie ya myocardial na hypertrophy yumutima, imikorere yumutima izagabanuka, kandi kunanirwa k'umutima bizaba byoroshye..
Byongeye kandi, ubushakashatsi bujyanye n’ubuvuzi bwemeje ko kugenzura ubwuzure bw’amaraso ya ogisijeni bifite akamaro kanini mu kuyobora mu kuvura indwara zifata umutima ndetse no kugereranya ibizaba.
Mu rwego rwo kwirinda neza kwangirika kwumubiri guterwa na hypoxia, ni ngombwa cyane gukurikirana ubwuzure bwa ogisijeni mu maraso mubuzima bwa buri munsi.Kuva havuka uburyo bwo gukurikirana ubwuzure bwamaraso ya ogisijeni kugeza ubu, pulisimu ya okisimeteri yakoreshejwe cyane mubikorwa byubuvuzi kubera ibyiza byayo bidatera, umutekano kandi wizewe, byoroshye gukoresha, bikora neza, bikomeza kandi mugihe, kandi bihendutse.Byahindutse ibikoresho byingenzi byo kwisuzumisha mubuvuzi mubyumba byihutirwa, mubyumba byo gukoreramo no mubyumba byita kubitaro.
Kurugero, mubyumba byihutirwa, monitor ya ogisijeni yamaraso irashobora guhora ikurikirana ubwuzure bwamaraso ya ogisijeni yumurwayi, hanyuma ikagena itangwa rya ogisijeni ukurikije agaciro kuzuye ka ogisijeni yapimwe, kugirango habeho itangwa rya ogisijeni neza kandi neza.
Mu cyumba cyo gukoreramo, monitor ya ogisijeni mu maraso irashobora guhora ipima ubwuzure bwa ogisijeni, cyane cyane ku barwayi barembye cyane ndetse no kubaga bafite umwuka mubi, irashobora gutanga vuba ogisijeni y’amaraso y’umurwayi vuba, kugira ngo abaganga bahite bafata ingamba zo gutabara ako kanya.Mucyumba cyo gukurikirana, monitor ya ogisijeni yamaraso irashobora gushyiraho ibintu bihuye bikurikije uko bihuye.Iyo umurwayi agaragaye afite apnea, umuvuduko muke wamaraso wa ogisijeni, umuvuduko wumutima, umuvuduko wumutima, nibindi.
Byongeye kandi, ni ngombwa cyane mugukurikirana abana bavuka, cyane cyane kumva neza kumenya hyperoxia cyangwa hypoxemia muri neonates no ku bana batagejeje igihe, hanyuma ugahindura itangwa rya ogisijeni y'ibikoresho bitanga ogisijeni mugihe gikurikije ibisubizo byakurikiranwe kugirango wirinde guhungabanya umutekano. uruhinja.kwangiza ubwonko, amaso, n'ibihaha by'abana.Muri icyo gihe, abantu benshi bambara oximeter yo mu rugo nabo bageze mubitekerezo byabantu, kandi bikoreshwa cyane mugupima, gusuzuma, kwiyobora nibindi.
Kurugero, gukurikirana uko umwuka wuzuye wa ogisijeni wamaraso mugihe kugirango wumve uburyo bwubuhumekero bwumukoresha nubuzima bwumutima nimiyoboro y'amaraso, kugirango tumenye niba bafite hypoxemia vuba bishoboka, kugirango birinde neza cyangwa kugabanya impfu zimpanuka ziterwa na hypoxia.
Byongeye kandi, oximeter irashobora kandi gukoreshwa mugupima indwara zo kumira, gusuzuma syndrome de apnea, no gusuzuma ibipimo byamaraso.Hanyuma, oximeter yo murugo nayo ifite imirimo ikurikira yo kwiyobora - nk'ubuyobozi bwo kuvura ogisijeni, kandi abarwayi bafite ibibazo byubuhumekero budakira barashobora kwiyobora murugo.
Byongeye kandi, monitor ya ogisijeni yamaraso nayo ikoreshwa cyane mubushakashatsi bwubuvuzi nubuvuzi.Kurugero, mubushakashatsi bwibitotsi bihumeka umwuka wa ogisijeni, kugenzura ubwuzure bwamaraso ya ogisijeni bikoreshwa mugupima niba umurwayi afite syndrome de apnea cyangwa nijoro ogisijeni yuzuye.Kwiyuzuza gake hamwe nibindi bihe, isuzumabumenyi rya nyuma ryindwara zidakira zidakira.
Irashobora kandi gukoreshwa mubushakashatsi bwimikino yubuzima bwabantu kandi ikagira uruhare runini mubindi bice byinshi nka: igisirikare, icyogajuru nibindi.Mu bihe biri imbere, ibyuma byuzuza amaraso ya ogisijeni yuzuye bizakoreshwa cyane mu kwita ku buzima bwo mu rugo no kwita ku buzima bw’abaturage, ibyo bikaba bizagira akamaro kanini mu gukumira no gusuzuma indwara z’abantu.Mu ngamba z’ubushakashatsi n’iterambere rya oximeter, Narigmed, yiyemeje gukomeza kunoza neza ibipimo bya oximeter, guhora tunonosora imikorere idahwitse yimikorere no kurwanya imyitozo ngororamubiri, kandi utegereje kuzana inkuru nziza kubantu benshi, tekinoroji ya ogisijeni ya Narigmed yigenga irigenga Uburenganzira ku mutungo wubwenge, no muri parufe nkeya PI = 0.025% Irashobora gukomeza kugumana ukuri kwa ogisijeni yamaraso no gupima igipimo cya pulse munsi ya ultra-low nkeya ya parufe hamwe ninshuro runaka yimikorere ihamye kandi igenda itunguranye, nta gushidikanya ko ari umuyobozi mubuvuzi bwubushinwa. ibigo by'ibikoresho.
