Inqaku loMhleli: Eli nqaku, libhalwe ngo-2015, liyaqhubeka nokuba lelona lifundwa kakhulu24×7indawo.Siyathemba ukuba ingakunika ulwazi oludingayo njengoko uvavanya iSpO2abenzi boluvo.
Ukubeka iliso SpO2, ipesenti yokuzalisa ioksijini egazini, iye yaba ngumgangatho wokunyamekela abaguli ehlabathini lonke.Phantse wonke umntu obeka iliso kwisigulane unesakhono esakhelwe ngaphakathi okanye esincamathelayo sokubeka iliso olu phawu lubalulekileyo.SPO2yindlela engathanga ngqo nengaphazamisiyo yokulinganisa ukugcwala kweoksijini egazini.Kufuneka ivavanywe kunye nazo zonke ezinye iiparamitha ze-physiological ngexesha lokukhusela okanye ukulungiswa kokulungiswa kwi-monitor yesigulane, okanye isixhobo esizimeleyo.
IThekhinoloji
SpO2ilinganiswa kwiperiphery, ngokuqhelekileyo umnwe, kwaye ngumlinganiselo omnye wempilo ye-cardiovascular and respiration systems.I-pulse oximeter ilinganisa ngokungaqhelekanga ukugcwala kweoksijini egazini lesigulana.Esi sixhobo siqulathe umthombo wokukhanya obomvu kunye ne-infrared, izikhangeli zeefoto, kunye neprobe yokuhambisa ukukhanya kwi-translucent, pulsating arterial bed, ngokwesiqhelo yincam yomnwe okanye indlebe.Ihemoglobin eneoksijini (O2Hb) kunye ne-deoxygenated hemoglobin (HHb) ifunxa ukukhanya okubomvu kunye ne-infrared ngokwahlukileyo.Ipesenti ye-saturation ye-hemoglobin egazini le-arterial ingabalwa ngokulinganisa utshintsho lokufunxa ukukhanya okubangelwa yi-arterial blood flow pulsations.
Izinto ezahlukeneyo zinokuchaphazela ukuchaneka kwe-SPO2umlinganiselo, kubandakanywa iimeko zolusu, umbala, amanxeba, izicubu ezibomvu, iitattoos, i-nail polish, i-hypothermia, i-anemia, amayeza, ukuphazamiseka kokukhanya kunye nokuhamba.
SPO2kulinganiswa kusetyenziswa isixhobo soluvo, esidla ngokubotshelelwa emnweni womguli.Kukho iindlela ezimbini ze-SpO2ubuchwepheshe: transmissive and reflective.Indlela yokudlulisela yeyona isetyenziswa kakhulu kwezi zimbini.Njengoko kubonisiwe kumfanekiso woku-1, itekhnoloji ye-transmissive transmissive ihambisa ukukhanya okubomvu kunye ne-infrared ngomnwe kwisixhobo sefoto.
Umzobo 1: Itekhnoloji yokudlulisa, eyona ndlela isetyenziswa ngokuqhelekileyo yeklinikhi ye-pulse oximetry.Cofa ukwandisa.Enye indlela esetyenziswa kwi-SPO2ithembele kwitekhnoloji yokubonakalisa.Njengoko kubonisiwe kuMfanekiso 2, le ndlela ine-transmitter kunye nomamkeli kwinqwelomoya efanayo.I-SPO ebonakalisayo2abenzi boluvo banokubekwa kwezinye iindawo ze-anatomy kunomnwe, njengebunzi.
Umzobo 2: Itekhnoloji ebonakalisayo, enye indlela kwimilinganiselo yokudlulisa.Cofa ukwandisa
Uvavanyo
Umenzi wesixhobo se-pulse oximetry ngamnye kufuneka aqinisekise ukuchaneka kwesixhobo sakhe ngokuqhuba uvavanyo lomntu.Njengoko uDennis J. McMahon echaza kwiphepha lakhe elimhlophe, "Ayikho into efana ne-SpO2Isifanisi,”1"kuphononongo olulawulwayo lokuchithwa kwe-desaturation, abantu abavolontiya baphefumla ulandelelwano lwemixube yegesi yokunciphisa umxholo we-oksijini ngelixa beqhagamshelwe kwi-monitor prototype."Iisampulu zegazi ze-Arterial zithathwa kwizifundo ukulinganisa ukugcwala kweoksijini kwilabhoratri yeklinikhi.
Isiphumo solu vavanyo yigrafu yaloo modeli ithile ye-SPO2inzwa kunye nokubeka iliso.Le grafu kubhekiselwa kuyo njenge-R-curve.Njengoko kubonisiwe kwi-Figure 3, i-R-curve ichaza ubudlelwane phakathi komlinganiselo othile wokukhanya obomvu kunye ne-infrared ngokubhekiselele kwi-oksijini ebonwayo njengoko iqokelelwe ngexesha lovavanyo lomntu.I-R-curve isetyenziswa kwi-firmware yesixhobo esithile kunye ne-SPO2abavavanyi.
Umzobo 3: Umzekelo we-R-curve, ehambelana ne-O2 saturation kunye nexabiso le-R.Cofa ukuze ukhulise iiSimulators, ii-calibrators, kunye nabavavanyi abasebenzayo bee-pulse oximeters zichazwe kumgangatho we-ISO 80601-2-61.Ngokungafaniyo nezinye iintlobo zezixhobo zonyango, i-pulse oximeters ayenzelwanga ukuba ilinganiswe ngaphandle komzi-mveliso.Azikho iindlela ezamkelweyo zokuqinisekisa ulungelelwaniso oluchanekileyo lwe-pulse oximeter ngaphandle kovavanyo lomntu.Uninzi lwe-SpO2izixhobo zovavanyo kwimarike zikudidi umvavanyi olusebenzayo.
Ngokutsho kukaTobey Clarke kwincwadi yakheUQinisekiso loMgangatho weZixhobo zoNyango, abahloli bezigulane kufuneka bavavanywe ukusebenza ubuncinane ngonyaka.2Uninzi lwabavavanyi abasebenzayo bavavanya i-SPO2isivamvo sokujonga.Oku kuvumela uvavanyo lwenzwa, intambo, kunye nokubeka iliso.Abanye abavavanyi abasebenzayo bafaka umqondiso ngqo kwimonitha, ukuvavanya kuphela imonitha.Abanye banokuvavanya intambo ngokuqhubekayo.Uninzi lwabavavanyi abasebenzayo bavavanya kuphela itekhnoloji yokuhambisa, hayi ukubonakalisa.
Ukuhamba komsebenzi oqhelekileyo wokuvavanya imonitha yesigulane okanye i-SPO ezimeleyo2iliso libandakanya ukujonga imeko yomzimba, ukwenza iimvavanyo zokhuseleko lombane, ukwenza nayiphi na imveliso ecetyisiweyo yokugcinwa kokuthintela, ukwenza uvavanyo lokusebenza (kubandakanywa i-alamu kunye nezinye iimvavanyo ezithile), kwaye, ekugqibeleni, ukubhala iziphumo zovavanyo.
