Iimbaleki ezizamela iziphumo ezikwinqanaba eliphezulu kwaye zijonge ukufezekisa umsebenzi ogqwesileyo kwiinjongo zazo ngokuzilolonga okunzima ukukhuphisana nokuphakamisa ukhuphiswano.Nangona kunjalo, ukubeka iliso kwiimpembelelo zokuzilolonga kubalulekile kolu sukelo njengendlela yokuqinisekisa inkqubela kunye nokuphumeza impumelelo yexesha elizayo.
Ukuze kunyuswe imisebenzi yomzimba ukwandisa imisebenzi yemiphunga kubaluleke kakhulu.I-Metabolism, uxinzelelo lwegazi kunye nokusebenza kwezihlunu zonke zixhomekeke kumandla emiphunga ukuhambisa ioksijini kuyo yonke inkqubo.
Ukuqinisekisa ukuba amanqanaba eoksijini ahlala phakathi koluhlu oluqhelekileyo luya kuphakamisa kwaye luphucule ukusebenza.Ngenkqubela phambili yamva nje kwezesayensi kunye netekhnoloji yokusika ukufumana amaqondo amancinci okulinganisa ioksijini ngaphambi, ngexesha nasemva kokusebenza ngenene kulula kwaye kuyasebenza ngokusetyenziswa kwe-compact kunye ne-pulse oximeters echanekileyo.
Izixhobo zokuxilonga ezifana ne-pulse oximeters ngumzekelo wesixhobo sonyango esisetyenziselwa ukulinganisa inqanaba le-oxygen (okanye i-oxygen saturation, i-Sp02) ngaphakathi kwegazi.Aziyi-invasive, ayinabuhlungu kwaye isetyenziswa ngokubanzi kwintsimi yezonyango kunye nabantu abasebenza okanye abaqeqeshelwa kwiindawo eziphakamileyo basebenzise izixhobo.
Xa ioksijini itsalwa emiphungeni ize idlulele egazini, uninzi lweoksijini incamathela kwihemoglobin (iprotein efumaneka kwiiseli ezibomvu zegazi) emva koko ithuthelwe egazini.Xa oku kusenzeka, igazi elineoksijini lijikeleza kwaye lisasazwa kwiithishu.Ukuba umzimba awufumani ioksijini eyaneleyo ngoko ke imizimba yethu inokuphuhlisa imeko eyaziwa ngokuba yi-hypoxia eqhelekileyo.Ngelishwa, oku kunokwenzeka nakwiimeko ezininzi kubantu abaziqeqesha nzima ngokwasemzimbeni.
Itekhnoloji ye-finger pulse oximeter ixhomekeke ekufunxeni ukukhanya kwe-hemoglobin kunye nendalo ebethayo yokuhamba kwegazi ngaphakathi kwemithambo ukumisela ukugcwala kweoksijini, i-Sp02.
Kwi-pulse oximeter, imithombo emibini yokukhanya (obomvu kunye ne-infrared) ikhanyisa ukukhanya ngomnwe kunye nakwi-photodetector kwicala elingasemva.Ngenxa yokuba izisombululo ezibini zokukhanya zixutywe ngokwahlukileyo nge-deoxyhemoglobin ngaphezu kwe-oxyhemoglobin, uhlalutyo lwesiginali luya kuvumela ukugcwala kwe-oxygen kunye ne-pulse ukuba ilinganiswe.Ngokutsho koogqirha imida eqhelekileyo eyamkelekileyo inokusuka kuma-95 ekhulwini, nangona ixabiso ukuya kutsho kuma-90 ekhulwini liqhelekileyo.
Xa iimbaleki zizilolonga ngamandla okanye ngamandla, kukho ukuthambekela kokuba amanqanaba e-oksijini egazi ehle.Nangona kunjalo isicwangciso esiyimpumelelo sokuzilolonga okanye irejimeni ihambelana nokuba nezihlunu ezityebileyo ngeoksijini ziphucula ukusebenza kwemisipha kunye nokusebenza ngokubanzi.Ukongeza, i-pulse oximeters inokuphinda kabini njengesixhobo sovavanyo kubathengi babaqeqeshi bobuqu abanokuphazamiseka kwemiphunga okanye ukusebenza kwentliziyo.Oku kubenza babe sisixhobo esihle sokuhlola ukukhokela uqeqesho kunye nokwandisa amandla.
I-Finger pulse oximeters zizixhobo zoqeqesho eziluncedo.Kulula ukuzisebenzisa kwaye zihlangene ukuze zingachaphazeli ukuzilolonga koqeqesho.Zikwayindlela ebalaseleyo yokuba wena okanye umntu omqeqeshayo akhulule amandla akhe angasetyenziswanga.
