Ọbara oxygen saturation bụ otu n'ime ihe dị mkpa na-egosi ahụike anụ ahụ.Ekwesịrị idobe njupụta oxygen oxygen nke ndị nwere ahụike n'etiti 95% na 100%.Ọ bụrụ na ọ dị ala karịa 90%, ọ abanyela na oke hypoxia.% bụ hypoxia siri ike, nke ga-emebi nnukwu ahụ ma tinye ndụ n'ihe egwu.
Ọbara oxygen saturation bụ ihe dị mkpa physiological parameter nke na-egosipụta ọrụ iku ume na ọbara.Dị ka ọnụ ọgụgụ na-ezughị ezu, ọtụtụ n'ime ihe kpatara mkparịta ụka mberede na ngalaba iku ume na ngalaba ndị dị mkpa na ụlọ ọgwụ na-emetụta oxygen ọbara.Anyị niile maara na ikuku oxygen dị ala enweghị ikewapụ ya na ọrịa iku ume, ma ọ bụghị ihe niile na-ebelata ikuku oxygen saturation nke ọrịa iku ume na-akpata.
Kedu ihe na-ebute saturation oxygen dị ala?
1. Ma nrụgide akụkụ nke oxygen inhaled dị oke ala.Mgbe ikuku oxygen na-ekukuru ezughi oke, saturation oxygen nwere ike ibelata.N'ịkọkọta na akụkọ ahụike ahụike, ekwesịrị ịjụ onye ọrịa ma ọ dịlarị elu ugwu dị elu karịa 3000m, ụgbọ elu dị elu, ịrịgo ka ọ gbasasịrị mmiri, na ogbunigwe ikuku na-adịghị mma.
2. Ma enwere mgbochi ikuku.Ọ dị mkpa ịtụle ma enwere hypoventilation nke na-egbochi ọrịa ndị dị ka ụkwara ume ọkụ, COPD, mgbọrọgwụ mgbọrọgwụ, na mgbochi anụ ahụ nke mba ọzọ nke nzuzo iku ume.
3. Ma enwere arụ ọrụ ikuku.Ọ dị mkpa icheta ma onye ọrịa ahụ nwere oke oyi baa, ụkwara nta siri ike, fibrosis na-agbasa pulmonary interstitial fibrosis, pulmonary edema, pulmonary embolism na ọrịa ndị ọzọ na-emetụta ọrụ ikuku.
4. Kedu ogo na ọnụọgụ Hb nke na-ebuga oxygen n'ime ọbara.Ọdịdị nke ihe ndị na-adịghị mma, dị ka nsị CO, nsị nitrite, na mmụba dị ukwuu na hemoglobin na-adịghị mma, ọ bụghị nanị na-emetụta ibufe oxygen n'ime ọbara, kamakwa na-emetụta ntọhapụ nke oxygen.
5. Ma onye ọrịa ahụ nwere nrụgide colloid osmotic kwesịrị ekwesị na oke ọbara.Nrụgide osmotic colloid kwesịrị ekwesị na oke ọbara zuru oke bụ otu n'ime isi ihe na-eme ka ikuku oxygen na-adị mma.
6. Gịnị bụ mmepụta obi onye ọrịa?Ịdokwa ikuku oxygen na-ebuga akụkụ ahụ kwesịrị ịbụ ihe nkwado zuru oke nke obi.
7. Tissue na akụkụ microcirculation.Ikike ịnọgide na-enwe oxygen kwesịrị ekwesị na-emetụtakwa metabolism nke anụ ahụ.Mgbe metabolism nke anụ ahụ buru ibu, a ga-ebelata ọdịnaya oxygen nke venous, na ọbara venous ga-eduga na hypoxia siri ike karị mgbe ọ gafesịrị na mgbasa nke akpa ume.
8. Oxygen itinye n'ọrụ na anụ ahụ gbara ya gburugburu.Mkpụrụ ndụ anụ ahụ nwere ike iji oxygen na-akwụghị ụgwọ, na oxygen jikọtara na Hb nwere ike iji naanị anụ ahụ mgbe ewepụtara ya.Mgbanwe na pH, 2,3-DPG, wdg. na-emetụta mwepu nke oxygen site na Hb.
9. Ike nke usu.A na-atụle saturation oxygen dabere na mgbanwe nke nnabata nke akwara akwara na-emepụta, yabụ, a ga-etinye transducer na saịtị nwere ọbara ọgbụgba.Ihe ọ bụla na-eme ka ọ ghara ịdị na-erugharị ọbara pulsatile, dị ka mkpali oyi, mkpali akwara obi ọmịiko, ọrịa shuga na ndị ọrịa arteriosclerosis, ga-ebelata nrịbama nke ngwá ọrụ ahụ.Enweghị ike ịhụ SpO2 ọbụlagodi na ndị ọrịa nwere ngafe obi na obi mgbachi.
