Amaraso ya ogisijeni yuzuye ni kimwe mu bimenyetso byingenzi byubuzima bwumubiri.Amaraso ya ogisijeni yamaraso yabantu basanzwe agomba kubikwa hagati ya 95% na 100%.Niba ari munsi ya 90%, yinjiye murwego rwa hypoxia.% ni hypoxia ikabije, izatera kwangirika cyane kumubiri no guhungabanya ubuzima.
Amaraso yuzuye ya ogisijeni ni ikintu cyingenzi kigaragaza imikorere yubuhumekero no gutembera.Dukurikije imibare ituzuye, impamvu nyinshi zitera inama zihutirwa n’ishami ry’ubuhumekero mu mashami bireba mu bitaro bifitanye isano na ogisijeni mu maraso.Twese tuzi ko kwiyuzuzamo umwuka wa ogisijeni muke ntaho bitandukaniye n'indwara z'ubuhumekero, ariko ntabwo kugabanuka kwuzuye kwa ogisijeni mu maraso biterwa n'indwara z'ubuhumekero.
Ni izihe mpamvu zitera kwiyuzuza amaraso ya ogisijeni?
1. Niba umuvuduko wigice cya ogisijeni ihumeka ari muke cyane.Iyo umwuka wa ogisijeni ushizwemo udahagije, kuzura ogisijeni birashobora kugabanuka.Ufatanije n’amateka y’ubuvuzi, umurwayi agomba kubazwa niba yarigeze kuba mu kibaya kiri hejuru ya 3000m, kuguruka ku butumburuke bwo hejuru, kuzamuka nyuma yo kwibira, ndetse n’ibirombe bidafite umwuka.
2. Niba hariho inzitizi zo mu kirere.Ni nkenerwa gusuzuma niba hariho hypoventilation itabangamira iterwa n'indwara nka asima, COPD, guta imizi y'ururimi, hamwe no kubuza umubiri w'amahanga kubuza imyanya y'ubuhumekero.
3. Niba hari imikorere idahwitse.Ni nkenerwa gutekereza niba umurwayi afite umusonga ukabije, igituntu gikomeye, diffuse pulmonary interstitial fibrosis, edmonary edema, pulmonary embolism nizindi ndwara zigira ingaruka kumikorere yo guhumeka.
4. Ni ubuhe bwoko n'ubwinshi bwa Hb itwara ogisijeni mu maraso.Kugaragara kw'ibintu bidasanzwe, nk'uburozi bwa CO, uburozi bwa nitrite, no kwiyongera kwinshi kwa hemoglobine idasanzwe, ntabwo bigira ingaruka zikomeye ku gutwara ogisijeni mu maraso, ahubwo bigira ingaruka zikomeye ku irekurwa rya ogisijeni.
5. Niba umurwayi afite umuvuduko ukabije wa osmotic hamwe nubunini bwamaraso.Umuvuduko ukwiye wa osloque osmotic hamwe nubunini bwamaraso buhagije nimwe mubintu byingenzi bigumana ubwuzure busanzwe bwa ogisijeni.
6. Indwara z'umutima z'umurwayi ni izihe?Kugumana itangwa rya ogisijeni isanzwe mu ngingo bigomba gushyigikirwa numutima uhagije.
7. Tissue na microcirculation organ.Ubushobozi bwo kubika ogisijeni ikwiye kandi bujyanye no guhinduranya umubiri.Iyo metabolisme yumubiri ari nini cyane, imyunyu ngugu ya ogisijeni yo mu maraso izagabanuka ku buryo bugaragara, kandi amaraso y’imitsi azatera hypoxia ikabije nyuma yo kunyura mu mitsi ihindagurika.
8. Gukoresha Oxygene mu ngingo zikikije.Utugingo ngengabuzima dushobora gukoresha gusa ogisijeni yubusa, kandi ogisijeni ihujwe na Hb irashobora gukoreshwa gusa nuduce iyo irekuwe.Impinduka muri pH, 2,3-DPG, nibindi bigira ingaruka ku gutandukana kwa ogisijeni kuva Hb.
9. Imbaraga za pulse.Kwiyongera kwa Oxygene gupimwa hashingiwe ku ihinduka ry’imitsi iterwa na arterial pulsation, bityo transducer igomba gushyirwa kurubuga rufite amaraso.Ibintu byose bigabanya umuvuduko wamaraso wa pulsatile, nko gukonjesha ubukonje, kwishima kwimpuhwe zumutima, diyabete nabarwayi ba arteriosclerose, bizagabanya imikorere yo gupima igikoresho.SpO2 ntishobora kuboneka no mubarwayi bafite byipi yumutima no gufatwa numutima.
