I-oximeter echanekileyo ephezulu edibana novavanyo lweklinikhi, "umsindisi osindisa ubomi" ngamaxesha anzima

Olu luvavanyo lokwenyani oluvela kumthengi waseAmazon.

Siyazi ukuba i-SpO2 iyipharamitha ebalulekileyo ebonisa umsebenzi wokuphefumula womzimba kunye nokuba umxholo we-oksijini uyinto eqhelekileyo, kwaye i-oximeter sisixhobo esihlola isimo se-oksijini yegazi emzimbeni wethu.I-oksijeni isisiseko semisebenzi yobomi, i-hypoxia yimbangela yezifo ezininzi, kunye nezifo ezininzi zingabangela ukunikezelwa kwe-oksijini eyaneleyo.I-SpO2 ngaphantsi kwe-95% yimbonakaliso ye-hypoxia epholileyo.Ngaphantsi kwe-90% yi-hypoxia enzima kwaye kufuneka iphathwe ngokukhawuleza.Akunjalo kuphela abantu abadala abanomdla kwi-hypoxemia, kodwa abantu banamhlanje banoxinzelelo oluninzi lwengqondo kunye nomsebenzi kunye nexesha lokuphumla.Izitenxo zihlala zikhokelela kwi-hypoxemia.Ixesha elide eliphantsi le-SpO2 liya kubangela ingozi enkulu kumzimba womntu.Ngoko ke, kuyimfuneko ukulinganisa i-SpO2 emzimbeni rhoqo, nangona amanyathelo okukhusela athatyathwa.

Xa kuziwa kwii-oximeters, kubasebenzisi besitayile sasekhaya kunye neengcali zokuqina komzimba, uninzi lwabantu luya kukhetha i-oximeters ephathekayo yeminwe, kuba intle, ixinene, kulula ukuyiphatha, kwaye ayikhawulelwanga lixesha kunye nendawo.Iluncedo kakhulu kwaye iyakhawuleza.Ii-clip oximeters zeminwe zikwasetyenziswa kwiindawo ezininzi zonyango lobuchwephesha, kodwa iimfuno zokuchaneka ziphezulu.Ngoko ke, ukupheliswa kweempazamo ngenye yezinto eziphambili zokulinganisa okuqinileyo kwe-oximeter.

Ukuchaneka kwe-oximeter kuhambelana ngokusondeleyo nomgaqo wobugcisa obuchwephesha be-oximeter.Imigaqo yoyilo yababoneleli besisombululo se-oximeter yangoku kwimarike ngokusisiseko iyafana: ukusetyenziswa kwe-LED ebomvu, i-infrared LED kunye nokwakheka kwefotodiode yesekethe ye-SpO2 sensor, kunye nesekethe ye-LED drive.Emva kokuba ukukhanya okubomvu kunye nokukhanya kwe-infrared kuhanjiswe ngomnwe, zichongwa yi-circuit processing circuit, kwaye emva koko zidluliselwe kwimodyuli ye-ADC ye-single-chip microcomputer ukubala ngakumbi ipesenti ye-SpO2.Zonke zisebenzisa izinto ezibuthathaka ezikhanyayo ezifana nokukhanya okubomvu, ukukhanya kwe-infrared LED kunye nefotodiode ukulinganisa ukuhanjiswa kweminwe kunye neendlebe.Nangona kunjalo, ababoneleli besisombululo se-oximeter abanemigangatho ephezulu kunye neemfuno zeprogram baneemfuno ezingqongqo kunye nezifuna kakhulu uvavanyo.Ukongeza kwiindlela zovavanyo eziqhelekileyo ezikhankanywe ngasentla, kufuneka basebenzise iimveliso zabo zeprogram kunye nokulinganisa okusemgangathweni kwe-oximeter.Idatha ithelekiswa ne-oximeter ye-medical-grade.

I-oximeter ephuhliswe yi-Medlinket ifundwe ngeklinikhi kwizibhedlele ezifanelekileyo.Kuphononongo lwe-saturation olulawulwayo, i-SaO2 yoluhlu lomlinganiselo wemveliso ye-70% ukuya kwi-100% iqinisekisiwe.Xa kuthelekiswa nexabiso le-SpO2 ye-arterial elinganiswe yi-CO-Oximeter, idatha echanekileyo ifunyenwe.Iphutha le-SpO2 lilawulwa kwi-2%, kwaye impazamo yokushisa ilawulwa kwi-0.1 ℃, enokufikelela kumlinganiselo ochanekileyo we-SpO2, ubushushu kunye ne-pulse., Ukuhlangabezana neemfuno zomlinganiselo wobungcali.

Ukukhetha i-Medlinket enexabiso eliphantsi kunye nesisombululo esichanekileyo se-oximeter kwimarike, ndiyakholelwa ukuba iya kufumana ngokukhawuleza ukuthandwa kwabasebenzisi.
