Hypoxemia

Hypoxemia ni igipimo gito cy'umwuka mu maraso. Itangira mu mitsi y'amaraso yitwa arteries. Hypoxemia si indwara cyangwa uburwayi. Ni ikimenyetso cy'ikibazo gifitanye isano no guhumeka cyangwa imiterere y'amaraso. Bishobora gutera ibimenyetso nka: Guhumeka nabi. Guhumeka vuba. Gukubita k'umutima cyane cyangwa cyane. Gusinzira. Igipimo cyiza cy'umwuka mu mitsi y'amaraso ni hafi mm Hg 75 kugeza kuri 100. Hypoxemia ni igipimo icyo ari cyo cyose kiri munsi ya mm Hg 60. Ibipimo by'umwuka na gaze y'imyanda ya carbone dioxyde bipimwa hakoreshejwe igipimo cy'amaraso cyafashe mu mitsi y'amaraso. Ibi bita isuzuma ry'amaraso arterial. Akenshi, umubare w'umwuka utwarwa n'utubuto tw'amaraso itukura, twitwa oxygen saturation, ni wo upimwa mbere. Upimwa hakoreshejwe igikoresho cy'ubuvuzi gifata ku rutoki, cyitwa pulse oximeter. Ibipimo byiza bya pulse oximeter akenshi biri hagati ya 95% na 100%. Ibipimo biri munsi ya 90% bifatwa nk'ibito. Akenshi, kuvura hypoxemia birimo kwakira umwuka mwinshi. Ubu buryo bwo kuvura bwitwa umwuka wongerwamo cyangwa oxygen therapy. Ubundi buryo bwo kuvura buhingamiye ku ntandaro ya hypoxemia.

Ushobora kumenya ko ufite hypoxemia iyo ugannye kwa muganga kubera guhumeka nabi cyangwa ikindi kibazo cyerekeye umwuka. Cyangwa ushobora gusangiza muganga ibyavuye mu bipimo bya pulse oximetry wakoreye mu rugo. Niba ukoresha pulse oximeter mu rugo, menya ibintu bishobora gutuma ibyavuye bitagira umwimerere: Imikorere mibi y'amaraso. Uruhu rwirabura cyangwa rw'umukara. Uburebure cyangwa ubushyuhe bw'uruhu. Kunywa itabi. Ibara ry'imisumari. Niba ufite hypoxemia, intambwe ikurikira ni ukumenya icyayiteye. Hypoxemia ishobora kuba ikimenyetso cy'ibibazo nkibi: O2 nke mu mwuka uhumeka, nko ku migezi miremire. Guhumeka buhoro cyangwa buke kugira ngo bihaze ibyo ibihaha bikeneye bya O2. Hari ubwo amaraso adatembera bihagije mu bihaha cyangwa O2 itageze mu bihaha. Kugira ikibazo cyo kwinjira kwa O2 mu maraso no kuvaho kw'imyuka mibi ya dioxyde de carbone. Ikibazo cy'uburyo amaraso atembera mu mutima. Impinduka zidasanzwe kuri poroteyine yitwa hemoglobin, itwara O2 mu bicurane bitukura. Intandaro za hypoxemia zifitanye isano n'ibibazo by'amaraso cyangwa imikorere y'amaraso harimo: Anemia Ibibazo by'umutima ku bana bavutse bafite - ibibazo by'umutima abana bavutse bafite. Indwara z'umutima ku bakuru - ibibazo by'umutima abantu bakuru bavutse bafite. Ibintu byo guhumeka bishobora gutera hypoxemia birimo: ARDS (acute respiratory distress syndrome) - kubura umwuka kubera gukusanya amazi mu bihaha. Asthme COPD Indwara z'ibihaha z'imbere - izina rusange ry'itsinda rinini ry'ibibazo bikomeretsa ibihaha. Pneumonia Pneumothorax - ibihaha byaguye. Pulmonary edema - amazi menshi mu bihaha. Pulmonary embolism Pulmonary fibrosis - indwara ibaho iyo umubiri w'ibihaha wangirika ukakomereka. Sleep apnea - ikibazo aho guhumeka guhagarara kandi bigatangira kenshi mu gihe cyo kuryama. Imiti imwe ishobora gutera guhumeka buhoro, buke ishobora gutera hypoxemia. Ibi birimo imiti imwe ihagarika ububabare bwa opioid n'imiti ibuza ububabare mu gihe cy'abaganga n'ibindi bikorwa, bitwa anesthésiques. Ibisobanuro Ryari ukwiye kujya kwa muganga
