Umzimba ugcina njani amanqanaba aqhelekileyo e-SpO2?Ukugcina i-oxygen saturation eqhelekileyo yegazi kubalulekile ukukhusela i-hypoxia.Ngethamsanqa, umzimba udla ngokwenza oku ngokwawo.Eyona ndlela ibalulekileyo yokuba umzimba ugcine usempilweniSpO2amanqanaba angokuphefumla.Imiphunga ifunxa ioksijini esele irhoxiwe ize iyibophe kwihemoglobin, emva koko ihemoglobin idluliselwe emzimbeni kunye neoksijini.Kuxinzelelo oluphezulu lomzimba (njengokuphakamisa iintsimbi okanye ukubaleka) kunye nokuphakama okuphezulu, imfuno yeoksijini yomzimba iyanda.Ngethuba nje bengagqithisi kakhulu, umzimba udla ngokukwazi ukuziqhelanisa nolu lwando.
Ukulinganisa ukugcwala kweoksijini yegazi
Zininzi iindlela zokuvavanya igazi ukuqinisekisa ukuba linamanqanaba aqhelekileyo oksijini.Eyona ndlela iqhelekileyo kukusebenzisa i-pulse oximeter ukulinganisa amanqanaba e-SpO2 egazini.I-Pulse oximeters ilula ukuyisebenzisa kwaye ixhaphake kumaziko ezonyango kunye neentsapho.Nangona ixabiso labo liphantsi, ichanekile kakhulu.Ukusebenzisa i-pulse oximeter, yibeke nje emnweni wakho.Ipesenti iya kuboniswa kwisikrini.Ipesenti kufuneka ibe phakathi kwe-94% kunye ne-100%, ebonisa ukuba i-hemoglobin ehambisa i-oksijini ngegazi ikwizinga eliphilileyo.Ukuba ingaphantsi kwama-90%, kufuneka ubone ugqirha.
I-pulse oximeter iyenza njani ioksijini egazini
I-pulse oximeter isebenzisa i-sensor yokukhanya ukurekhoda ukuba igazi lingakanani na i-oksijini kwaye lingakanani igazi elingathwali i-oksijini.I-Oxygen-saturated hemoglobin ikhangeleka ibomvu ngokuqaqambileyo kwiliso leze kune-non-oxygen-saturated hemoglobin.Le nto yenza ukuba i-sensor ebukhali kakhulu ye-pulse oximeter ibone utshintsho oluncinci egazini kwaye luguqulelwe ekufundeni.
Kukho iimpawu ezininzi eziqhelekileyo ze-hypoxemia.Inani kunye nobukhulu bezi mpawu zixhomekeke kwinqanabaSpO2.I-hypoxemia ephakathi inokubangela ukudinwa, ukuba nesiyezi, ukuba ndindisholo, kunye nokutshotshozela kwamalungu kunye nesicaphucaphu.Ngaphaya kweli nqaku, i-hypoxemia ihlala iba yi-hypoxic.
Amanqanaba e-SpO2 aqhelekileyo ayimfuneko ekugcineni impilo yazo zonke izicubu emzimbeni.Njengoko bekutshiwo ngaphambili, i-hypoxemia kukugcwala kweoksijini ephantsi egazini.I-Hypoxemia inxulumene ngokuthe ngqo ne-hypoxia, ephantsi kwe-oxygen saturation kwizicubu zomntu.Ukuba umxholo we-oksijeni uphantsi kakhulu, i-hypoxemia idla ngokukhokelela kwi-hypoxia, kwaye ihlala kule meko.Ubunzulu obumfusa-bomvu luphawu olulungileyo lwe-hypoxemia ekubeni yi-hypoxic.Nangona kunjalo, ayithembekanga ngokupheleleyo.Umzekelo, abantu abanolusu olumnyama abayi kuba ne-osis emfusa ecacileyo.Xa i-hypoxia iba nzima kakhulu, i-yan syndrome emfusa idla ngokusilela ukuphucula ukubonakala.Nangona kunjalo, ezinye iimpawu ze-hypoxia ziba nzima ngakumbi.I-hypoxia emandla inokubangela ukuxhuzula, ukubhideka, ukubona izinto ezingekhoyo, i-pallor, ukubetha kwentliziyo okungaqhelekanga kunye nokufa.I-Hypoxia ngokuqhelekileyo ivelisa umphumo we-snowball, kuba xa inkqubo iqala, ikhawuleza kwaye imeko ikhawuleza ibe yimbi ngakumbi.Umgaqo omhle wesithupha kukuba ngokukhawuleza ukuba ulusu lwakho luqala ukuthatha i-tint bluish, kufuneka ufune uncedo ngokukhawuleza.
