Kutshanje, i-pulse oximetry (SpO2) ifumene ingqwalasela eyongeziweyo eluntwini kuba abanye oogqirha bacebisa ukuba abaguli abafunyenwe bene-COVID-19 bajonge amanqanaba abo e-SpO2 ekhaya.Ke ngoko, iyavakala ukuba abantu abaninzi bazibuze "Yintoni i-SpO2?"okokuqala.Ungakhathazeki, nceda ufunde kwaye siya kukukhokela ukuba yintoni iSpO2 kunye nendlela yokulinganisa.
I-SpO2 imele i-blood oxygen saturation.Abantu abadala abaphilileyo badla ngokuba ne-95% -99% ye-saturation yegazi, kwaye naluphi na ukufundwa ngaphantsi kwe-89% ngokuqhelekileyo kubangele ukukhathazeka.
I-pulse oximeter isebenzisa isixhobo esibizwa ngokuba yi-pulse oximeter ukulinganisa ubungakanani beoksijini kwiiseli ezibomvu zegazi.Isixhobo siya kubonisa eyakhoSpO2njengepesenti.Abantu abanezifo zemiphunga ezifana nesifo esingapheliyo semiphunga (COPD), isifuba okanye inyumoniya, okanye abantu abayeka ukuphefumla okwexeshana ngexesha lokulala (i-apnea yokulala) banokuba namanqanaba asezantsi e-SpO2.I-Pulse oximetry inokubonelela ngesilumkiso sakwangoko kwiingxaki ezininzi ezinxulumene nemiphunga, yiyo loo nto abanye oogqirha becebisa ukuba izigulana zabo ze-COVID-19 zibeke iliso rhoqo kwi-SpO2 yazo.Ngokuqhelekileyo, oogqirha bahlala belinganisa i-SpO2 kwizigulana ngexesha lovavanyo olulula, kuba le yindlela ekhawulezayo nelula yokufaka iflegi yeengxaki zempilo okanye ukukhupha ezinye izifo.
Nangona ukususela ngeminyaka yee-1860 bekusaziwa ukuba ihemoglobin yinxalenye yegazi elithwala ioksijini liwuse umzimba wonke, kuya kuthabatha iminyaka engama-70 ukuze olu lwazi lusetyenziswe ngokuthe ngqo kumzimba womntu.Ngowe-1939, uKarl Matthes wavelisa uvulindlela we-pulse oximeters yanamhlanje.Wenza isixhobo esisebenzisa ukukhanya okubomvu kunye ne-infrared ukulinganisa ngokuqhubekayo ukugcwala kweoksijini endlebeni yomntu.Ngexesha leMfazwe Yehlabathi yesiBini, uGlenn Millikan wavelisa isicelo sokuqala esisebenzayo sale teknoloji.Ukuze acombulule ingxaki yokumka kombane komqhubi wenqwelo-moya ngexesha lokuqhuba kwindawo ephakamileyo, wadibanisa i-ear oximeter (igama awaliqambayo) kwinkqubo ehambisa ioksijini ngokuthe ngqo kwisigqubuthelo sobuso somqhubi wenqwelo-moya xa ufundo lweoksijini lwehla kakhulu .
Injineli yebhayoloji kaNihon Kohden uTakuo Aoyagi wenza i-oximeter yokuqala yokwenyani yepulse ngo-1972, xa wayezama ukusebenzisa i-ear oximeter ukulandelela ukuhlanjululwa kwedayi ukulinganisa isiphumo sesantya sentliziyo.Xa uzama ukufumana indlela yokulwa neempawu zesignali ezibangelwa yi-pulse yesifundo, waqaphela ukuba ingxolo ebangelwa yi-pulse yayibangelwa ngokupheleleyo utshintsho kwi-blood flow flow.Emva kweminyaka emininzi yomsebenzi, wakwazi ukuphuhlisa isixhobo esinamaza amabini esisebenzisa utshintsho kwi-arterial blood flow ukulinganisa ngokuchanekileyo izinga lokufunxa ioksijini egazini.U-Susumu Nakajima wasebenzisa le teknoloji ukuphuhlisa inguqulelo yokuqala yeklinikhi ekhoyo, kwaye waqala ukuvavanywa kwizigulane ngo-1975. Kwakungekho kwasekuqaleni kwe-1980 apho i-Biox yakhupha i-pulse oximeter yokuqala eyimpumelelo yorhwebo kwimarike yokhathalelo lokuphefumla.Ngo-1982, i-Biox yafumana iingxelo zokuba izixhobo zabo zisetyenziselwe ukulinganisa i-oxygen saturation yegazi yezigulane ezine-anesthetized ngexesha lotyando.Inkampani ngokukhawuleza yaqala umsebenzi kwaye yaqala ukuphuhlisa iimveliso ezilungiselelwe ngokukodwa ii-anesthesiologists.Ukusebenza kokulinganisa i-SpO2 ngexesha lotyando kwaqatshelwa ngokukhawuleza.Ngo-1986, i-American Society of Anesthesiologists yamkela i-intraoperative pulse oximetry njengenxalenye yomgangatho wayo wokunyamekela.Ngolu phuhliso, i-pulse oximeters isetyenziswe ngokubanzi kwamanye amasebe esibhedlele, ngakumbi emva kokukhululwa kwe-fingertip pulse oximeter yokuqala yokuzimela ngo-1995.
Ngokuqhelekileyo, iingcali zonyango zingasebenzisa iintlobo ezintathu zezixhobo ukulinganisaSpO2yesigulane: i-multi-function okanye i-multi-parameter, i-monitor yesigulane, i-bedside okanye i-oximeter ye-pulse ebanjwe ngesandla okanye i-fingertip pulse oximeter.Iindidi ezimbini zokuqala zabagadi ziyakwazi ukulinganisa izigulane ngokuqhubekayo, kwaye ziyakwazi ukubonisa okanye ukuprinta igrafu yeenguqu kwi-oxygen saturation ngexesha.I-Spot-check oximeters isetyenziselwa ikakhulu ukurekhoda kwe-snapshot ye-saturation yesigulane ngexesha elithile, ngoko ke ezi zisetyenziselwa iimviwo kwiikliniki okanye kwiiofisi zoogqirha.
