Olu luvavanyo lokwenyani oluvela kumthengi kwiAmazon.

Siyazi ukuba iSpO₂ yiparameter ebalulekileyo ebonisa umsebenzi womzimba wokuphefumla kunye nokuba umxholo weoksijini uqhelekile na, kwaye i-oximeter sisixhobo esijonga imeko yeoksijini egazini emzimbeni wethu. Ioksijini sisiseko semisebenzi yobomi, i-hypoxia yimbangela yezifo ezininzi, kwaye izifo ezininzi zinokubangela ukungonelanga kokunikezelwa kweoksijini. I-SpO₂ engaphantsi kwama-95% ibonisa i-hypoxia encinci. Ngaphantsi kwama-90% yi-hypoxia enzima kwaye kufuneka inyangwe ngokukhawuleza. Ayingobantu abadala kuphela abanokuchaphazeleka yi-hypoxemia, kodwa abantu banamhlanje banengxaki enkulu yoxinzelelo lwengqondo kunye nexesha lokusebenza kunye nokuphumla. Ukungalungelelani kudla ngokukhokelela kwi-hypoxemia. I-SpO₂ ephantsi ixesha elide iya kubangela umonakalo omkhulu emzimbeni womntu. Ke ngoko, kuyimfuneko ukulinganisa iSpO₂ emzimbeni rhoqo, nokuba kuthathwa amanyathelo okukhusela.

Xa kufikwa kwii-oximeters, kubasebenzisi besitayile sasekhaya kunye neengcali zempilo ezingoochwephesha, uninzi lwabantu luya kukhetha ii-oximeters eziphathekayo eziphathwayo ngeminwe, kuba zintle kakhulu, zincinci, kulula ukuzithwala, kwaye azithintelwa lixesha nendawo. Zilula kakhulu kwaye ziyakhawuleza. Ii-oximeters ze-finger clip zikwasetyenziswa kwiindawo ezininzi zonyango zobungcali, kodwa iimfuno zokuchaneka ziphezulu. Ke ngoko, ukususwa kweempazamo yenye yezinto ezibalulekileyo zokulinganisa i-oximeter ngokuqinileyo.

Ukuchaneka kwe-oximeter kunxulumene kakhulu nomgaqo wobuchwephesha wobuchwephesha we-oximeter. Imigaqo yoyilo lwababoneleli bezisombululo ze-oximeter ezikhoyo kwimarike ngokusisiseko iyafana: ukusetyenziswa kwe-LED ebomvu, i-infrared LED kunye nokwakheka kwe-photodiode kwisekethe yesenzwa ye-SpO₂, kunye nesekethe ye-LED drive. Emva kokuba ukukhanya okubomvu kunye nokukhanya kwe-infrared kudluliselwe ngomnwe, kuyabonwa yisekethe yokucubungula isignali, emva koko kudluliselwe kwimodyuli ye-ADC ye-single-chip microcomputer ukuze kubalwe ngakumbi ipesenti ye-SpO₂. Bonke basebenzisa izinto ezibuthathaka ekukhanyeni ezifana nokukhanya okubomvu, ukukhanya kwe-infrared LED kunye ne-photodiode ukulinganisa ukudluliselwa kweminwe kunye neendlebe. Nangona kunjalo, ababoneleli bezisombululo ze-oximeter abanemigangatho ephezulu kunye neemfuno zenkqubo baneemfuno zovavanyo ezingqongqo nezifuna kakhulu. Ukongeza kwiindlela zovavanyo zesiqhelo ezikhankanyiweyo apha ngasentla, kufuneka basebenzise iimveliso zabo zenkqubo kunye nokulinganisa kwe-oximeter yobungcali. Idatha ithelekiswa ne-oximeter yenqanaba lezonyango.

I-oximeter eyenziwe yiMedLinket ifundwe ngokwezonyango kwizibhedlele ezifanelekileyo. Kuphononongo olulawulwayo lokugcwala, i-SaO₂ yoluhlu lokulinganisa lwale mveliso oluyi-70% ukuya kwi-100% iqinisekisiwe. Xa kuthelekiswa nexabiso le-arterial SpO₂ elilinganiswe yi-CO-Oximeter, kufunyanwa idatha echanekileyo. Impazamo ye-SpO₂ ilawulwa kwi-2%, kwaye impazamo yobushushu ilawulwa kwi-0.1℃, enokufikelela kumlinganiselo ochanekileyo we-SpO₂, ubushushu, kunye ne-pulse. , Ukuhlangabezana neemfuno zomlinganiselo wobuchwephesha.

Ndikhetha isisombululo se-oximeter yokulinganisa esingabizi kakhulu nesichanekileyo seMedLinket kwimarike, ndikholelwa ukuba iya kukhawuleza ifumane ukuthandwa ngabasebenzisi.
