Dzidza zvakawanda nezvokuti paruzhinji miviri ropa yakazara okisijeni

Mune dzimwe nhengo ropa yakazara okisijeni? Mhinduro yomubvunzo uyu anoziva kwete vose. Zvisinei, zvachose wose anoziva kuti pane zvinokosha kuderera padanho gasi iri midziyo ropa rizere nehosha dzakasiyana-siyana kufema emuviri uye mwoyo tsandanyama.

Mune dzimwe nhengo ropa yakazara okisijeni?

Kuti tipindure mubvunzo uyu, tinofanira kutanga yeuka chikoro dingindira anatomi "systemic kutenderera". Pashure pezvose, panguva iyi muitiro nyama dzomuviri kuva zvakazara ose anodiwa zvinovaka muviri uye oxygen. Zvino zvinoitika zvinotevera nzira: kubva kuruboshwe ventricle mwoyo tsandanyama , arterial ropa zvishoma nezvishoma runoyerera kuburikidza arteries kuti zvomukati zvose muviri. Somugumisiro huru denderedzwa iri capillaries rudzi gasi exchange. Nemamwe mashoko, okisijeni kubva ropa anopinda munyama uye carbon dioxide, nekusiyana, akagovera kubva munyama kupinda ropa. The tsvuku corpuscles aneta uye venous mutsinga kupinda zvakanaka atrium, uye ipapo zvakarurama ventricle.

Blood okisijeni saturation rinowanikwa mumapapu. Anoziva nezvazvo mudzidzi anenge ose. Zviya, chinhu ichi zvaitambidzwa zvose zvomukati uye munyama, kwete chete nezvinhu zvedu dzinongoitika Pombi - moyo, asi nemhaka chaiwo inotakura mapuroteni, izvo huri tsvuku corpuscles kana vanonzi erythrocytes. In mushonga dzinonzi hemoglobin. Ndiye anoratidza zvakadini uye padanho ropa okisijeni saturation.

Norma okisijeni muropa

Mune dzimwe nhengo ropa yakazara okisijeni, takazoziva. Zvisinei, pakarepo mubvunzo unomuka pamusoro chii chakaipa nazvo zvayo. Zvinokosha kucherechedza kuti chakaipa ezvinhu anenge ose Chizenga anosunga oxygen. Saka pacharo saturation indekisi anoda kubva 96% kusvika 99%. Kana ichi sandara ipfupi uye igova asingasviki 95%, ipapo munhu vakachengeta zvakakomba vascular zvirwere, kufema maitiro uye mwoyo tsandanyama. Uyezve, zvikuru kupererwa neropa (i.e., ane chinokosha azvipire Chizenga iri akatura), murwere anogona kuona uye zvimwe zvachinja muviri (semuenzaniso, utera, kudzikira mbambo, ganda, etc.).

Kana murwere ari chirwere pakati mapapu uye mwoyo, kutsauka kwakadaro kunoratidza kuwedzera pamusoro chirwere. Pakadaro, unofanira pakarepo kutaura nyanzvi. Kana okisijeni saturation iri kuderera pamusoro mamiriro nemabayo, dzihwa, chikosoro nedzimwe chakasimba zvirwere kufema, izvozvo rinopupurira nechirwere asi chakakomba.

Nhema yakaderera wokufema

About dzavose miviri ropa yakazara okisijeni, taitaura zvishoma kwirirei. Zvino zvinofanira kucherechedzwa kuti panguva kuongororwa zvokurapa, pane zvinoverengeka kuti Anowanzoita kuti nhema yakaderera kuipa kwevari masero matsvuku eropa. Naizvozvo, nokuda zvakarurama chirwere kunokosha zvikuru kupedza mashomanana rabhoritari kuyerwa pamusara.
