Ngasekupheleni kwe-1990, izifundo ezininzi zenziwa ukuvavanya ukuchaneka kwabangengabo abachwephesha, abaphenduli bokuqala, i-paramedics kunye noogqirha ekuhloleni kuphela ubukho be-pulse.Kwisifundo esinye, izinga lokuphumelela lokuqatshelwa kwe-pulse laliphantsi njenge-45%, ngelixa kwelinye uphando, oogqirha abancinci bachitha umyinge wemizuzwana ye-18 ukuqaphela i-pulse.
Kungenxa yezi zizathu ukuba ngokweengcebiso zeKomidi yokuvuselela i-International Resuscitation Committee, i-British Resuscitation Committee kunye ne-American Heart Association ikhansele isheke se-pulse rhoqo njengophawu lobomi ukusuka kuqeqesho lokuqala loncedo oluhlaziyiweyo kwi-2000.
Kodwa ukujonga ukubetha kwentliziyo kuxabiseke ngokwenene, Njengazo zonke iimpawu ezibalulekileyo, ukwazi ukuba ukubetha kwentliziyo yalowo wonzakeleyo kuluhlu oluqhelekileyo kunokudlulisela inkcazelo ebalulekileyo kuthi;
Ukuba i-pulse yabalimeleyo ayikho phakathi kolu luhlu, inokusikhokelela kwiingxaki ezithile.Ukuba umntu uyabaleka, silindele ukuba i-pulse yabo iphakame.Sikwafuna ukuba babe shushu, babebomvu kwaye baphefumle ngokukhawuleza.Ukuba abazange babaleke, kodwa bashushu, babomvu, baphefumula ngokukhawuleza kunye ne-pulse esheshayo, sinokuba nengxaki, enokuthi ibonise i-sepsis.Ukuba ngaba yingozi;i-pulse eshushu, ebomvu, ecothayo kwaye eyomeleleyo, oku kungabonisa ukulimala kwentloko yangaphakathi.Ukuba bonzakele, bayagodola, baphatshile kwaye bane-pulse ekhawulezayo, banokuba nomothuko we-hypovolemic.
Siza kusebenzisa i-pulse oximeter:I-oximeter ye-Pulsesisixhobo esincinci sokuxilonga esisetyenziswa ikakhulu ukuchonga ukugcwala kweoksijini yegazi kwabonzakeleyo, kodwa sinokubonisa nokubetha kwabalimeleyo.Ngomnye wabo, akufuneki sichithe ixesha ukuze sifikelele amaxhoba kwaye sizive ukubethelwa ngamandla.
Indlela ye-pulse oximetry ilinganisa ubungakanani beoksijini ethwalwa egazini njengepesenti.Sebenzisa i-pulse oximeter ukulinganisa umnwe wakho.Lo mlinganiselo ubizwa ngokuba yi-Sp02 (i-peripheral oxygen saturation), kwaye luqikelelo lwe-Sp02 (i-arterial oxygen saturation).
I-hemoglobin kwiiseli ezibomvu zegazi ithwala ioksijini (ixabiso elincinci liyanyibilika egazini).Imolekyuli nganye yehemoglobin inokuphatha iimolekyuli zeoksijini ezi-4.Ukuba yonke i-hemoglobin yakho iboshwe kwiimolekyuli ezine ze-oksijeni, ngoko igazi lakho liya "kuhluthwa" nge-oksijeni, kwaye i-SpO2 yakho iya kuba yi-100%.
Uninzi lwabantu alunayo i-100% ye-oxygen saturation, ngoko ke uluhlu lwe-95-99% lubhekwa njengesiqhelo.
Nasiphi na isalathisi esingaphantsi kwe-95% sinokubonisa i-oksijeni ye-hypoxia-hypoxic iya kungena kwizicubu.
Ukuncipha kwe-SpO2 lolona phawu luthembekileyo lwe-hypoxia yokwenzakala;ukunyuka kwezinga lokuphefumula kuhambelana ne-hypoxia, kodwa kukho ubungqina bokuba olu xhulumaniso alunamandla ngokwaneleyo (kwaye lukhona kuzo zonke iimeko) ukuba lube luphawu lwe-hypoxia.
Ii-pulse oximetersisixhobo esikhawulezayo sokuxilonga esikuvumela ukuba ulinganise kwaye ubeke iliso kwinqanaba le-oxygenation yexhoba.Ukwazi ukuba i-Sp02 eyenzakeleyo inokukwenza ukuba unikeze isixa esifanelekileyo se-oksijini ngaphakathi koluhlu lwezakhono.
Nangona i-oxygen saturation yegazi ingaphakathi kwinqanaba eliqhelekileyo, i-SpO2 iyancipha nge-3% okanye ngaphezulu, nto leyo isalathiso sovavanyo olubanzi lwesigulane (kunye nesignali ye-oximeter), kuba oku kunokuba bubungqina bokuqala besifo esibi.
