Urwego rwa ogisijeni mu maraso (arterial maraso ogisijeni) yerekana urwego rwa ogisijeni igaragara mumaraso atembera mumitsi yumubiri.Ikizamini cya ABG gikoresha amaraso yavuye mu mitsi, ashobora gupimwa mbere yuko yinjira mu ngingo z'umuntu.Amaraso azashyirwa mumashini ya ABG (isesengura ryamaraso ya gaz), itanga urugero rwa ogisijeni yamaraso muburyo bwumuvuduko wa ogisijeni (umuvuduko wa ogisijeni).
Hyperoxaemia isanzwe igaragara hakoreshejwe ikizamini cya ABG, isobanurwa nkurwego rwa ogisijeni yamaraso iri hejuru ya mm 120Hg.Umuvuduko ukabije wa ogisijeni wa arterial (PaO2) wapimwe ukoresheje igipimo cyamaraso ya arterial (ABG) ni mm 75 kugeza 100 mmHg (75-100 mmHg).Iyo urwego ruri munsi ya 75 mmHg, iyi miterere ikunze kwitwa hypoxemia.Urwego ruri munsi ya 60 mmHg rufatwa nkurwego rwo hasi kandi rwerekana ko hakenewe ogisijeni yinyongera.Umwuka wa ogisijeni winyongera utangwa binyuze muri silindiri ya ogisijeni, ihuza izuru binyuze mu muyoboro ufite cyangwa udafite mask.
Umwuka wa ogisijeni ukwiye kuba uwuhe?
Urwego rwa ogisijeni mu maraso rushobora kandi gupimwa hakoreshejwe igikoresho cyitwa pulse oximeter.Urwego rusanzwe rwa ogisijeni muri pulse oximeter ni 95% kugeza 100%.Ibice biri munsi ya 90% byamaraso ya ogisijeni biri hasi (hypoxemia).Hyperoxaemia isanzwe igaragazwa nikizamini cya ABG, isobanurwa nkurwego rwa ogisijeni yamaraso iri hejuru ya mmHg 120.Ubusanzwe ibi biri mubitaro, mugihe umurwayi ahuye numuvuduko mwinshi wa ogisijeni winyongera mugihe kirekire (amasaha 3 kugeza 10 cyangwa arenga).
Niki gitera urugero rwa ogisijeni mumaraso kugabanuka?
Urwego rwa ogisijeni mu maraso rushobora kugabanuka kubera kimwe mu bibazo bikurikira:
Umwuka wa ogisijeni uri mu kirere ni muke: Ahantu hirengeye nko mu misozi, ogisijeni mu kirere iba mike cyane.
Ubushobozi bwumubiri wumuntu bwo gufata ogisijeni buragabanuka: Ibi bishobora guterwa nindwara z ibihaha zikurikira: Asima, emphysema (kwangiza imifuka yumuyaga mu bihaha), bronhite, umusonga, pneumothorax (umwuka uva mu bihaha nurukuta rwigituza), acute syndrome de santrale yubuhumekero (ARDS), indurwe yo mu bihaha (kubera kubyimba ibihaha byegeranijwe), fibrosis yo mu bihaha (inkovu y'ibihaha), indwara y'ibihaha hagati (umubare munini w'indwara zifata ibihaha zikunze gutera inkovu zihaha), kwandura virusi, nka COVID-19
Ibindi bintu birimo: kubura amaraso, gusinzira apnea (gusinzira uhumeka by'agateganyo), kunywa itabi
Ubushobozi bw'umutima bwo gutanga ogisijeni mu bihaha buragabanuka: impamvu ikunze kugaragara ni indwara z'umutima zavutse (inenge z'umutima ukivuka).
