Olu vavanyo oluyinyani kumthengi kwiAmazon.

Siyazi ukuba i-spo₂t yiparamitha ebalulekileyo ebonisa umsebenzi wokuphefumla komzimba kwaye nokuba umxholo weoksijini yinto eqhelekileyo, kwaye i-oximeter sisixhobo esibeka esweni imeko ye-oxtigen yegazi emzimbeni. Ioksijini sisiseko semisebenzi yobomi, i-hypoxia ngunobangela wezifo ezininzi, kwaye izifo ezininzi zinokubangela ukuba kunganikezeli ioksijini yeoksijini. I-Supowelower kune-95% ibonisa i-hypoxia ethambileyo. Ngaphantsi kwe-90% yi-hypoxia enzulu kwaye kufuneka aphathwe ngokukhawuleza. Asikuphela nje abalupheleyo bathambekele kwi-hypoxemia, kodwa abantu banamhlanje banoxinzelelo olukhulu lwengqondo kunye nomsebenzi kunye nexesha lokuphumla. Izitenxo zihlala zikhokelela kwi-hypoxemia. I-spot yexesha elide iya kubangela ingozi enkulu emzimbeni womntu. Ke ngoko, kuyimfuneko ukulinganisa i-spo₂ emzimbeni rhoqo, nokuba kuthathwa amanyathelo okhuselo.

Xa kufikwa kwi-oxiry, kubasebenzisi besibeleko sekhaya kunye neengcali zokuziqesha, uninzi lwabantu luya kukhetha ii-oximer-funser-funsen ezifumanekayo, ngenxa yokuba zikhutshiwe, zilula kakhulu, kwaye zingapheleli ngamaxesha nendawo. Ilula kakhulu kwaye ikhawuleza. Ii-Obaiplip ze-oxiter zikwasetyenziswa kwiindawo ezininzi zonyango, kodwa iimfuno zokuchazela ziphezulu. Ke ngoko, ukupheliswa kwezimpazamo yenye yezona zinto zibalulekileyo kumlinganiso we-oximeter.

Ukuchaneka kwe-oximeter inxulumene ngokusondeleyo ne-Ososimetri ye-Ososimeter. Imigaqo-siseko yoyilo ye-Obasim ye-Obasimeter yangoku kwimarike iyafana: Ukusetyenziswa kwe-LED ye-LED, infrared ye-LED kunye nesekethe ye-Potdiode kunye nesekethe ye-Computer. Emva kokukhanya okubomvu kunye nokukhanya kwe-infrared kuyadluliselwa ngomnwe, bafunyanwa yisekethe yokulungisa umqondiso, emva koko badlulela kwimodyuli ye-adc ye-chip ye-chip enye ukuya phambili ukubala ipesenti ye-spo₂. Zonke zisebenzisa izinto ezinokukhanya ezinokukhanya ezifana nokukhanya okubomvu, ukukhanya kwe-infrared ekhokelwa kunye ne-Photodiode ukulinganisa usulelo lweefayile kunye neendlebe. Nangona kunjalo, ababoneleli ngesisombululo se-obanga Aqonga abanemigangatho ephezulu kunye neemfuno zenkqubo ziye zakhawulezisa kwaye zifuna ezinye iimfuno zovavanyo. Ukongeza kwezi ndlela zibalulekileyo kuvavanyo olukhankanyiweyo apha ngasentla, kufuneka zisebenzise iimveliso zabo zenkqubo kunye neendlela zokusebenza ze-obam. Idatha ithelekiswa nenqanaba le-oximera yezamayeza.

I-oximeter ephuhliswe yiMedlitothi ifundwe ngokweekliniki kwizibhedlele ezifanelekileyo. Kwisifundo esilawulayo sangumbuso, i-SAO₂ yale milinganiselo yemveliso engama-70% ukuya kwi-100% iqinisekisiwe. Xa kuthelekiswa nexabiso lobugcisa elilinganiswe yi-co-oximeter, idatha echanekileyo ifunyenwe. Impazamo ye-Spo₂ ilawulwa nge-2%, kwaye imposiso yobushushu ilawulwa nge-0,1 ℃, enokufikelela kumlinganiso ochanekileyo we-spo₂, ubushushu, kunye ne-pullar. , Ukuhlangabezana neemfuno zomsebenzi wobungcali.

Ukukhetha iMedlitot yeMedlittion kunye ne-Apchanes ye-Otimeremermermer kwimarike, ndiyakholelwa ukuba iya kukhawuleza ifumane inkoliseko yabasebenzisi.
