i-oxygen saturation (i-SaO2) yipesenti yomthamo we-oxyhemoglobin (HbO2) eboshwe yi-oksijini egazini ukuya kumthamo opheleleyo we-hemoglobin (Hb, i-hemoglobin) enokuthi iboshwe yi-oxygen, oko kukuthi, ukuxinwa kwe-oksijini yegazi igazi.iiparamitha ezibalulekileyo zefiziyoloji.
I-blood oxygen saturation imele impilo yomzimba womntu kwaye inokubonisa impilo yenkqubo yokuphefumla yomntu kunye nenkqubo ye-cardiovascular system.Idlala indima ebalulekileyo ekuthinteleni nasekuxilongweni kwezifo zabantu.Ngoko ke, ukubeka iliso kwi-oksijeni yegazi kubaluleke kakhulu.intsingiselo yempilo.
Indlela yeklinikhi engabonakaliyo yokulinganisa i-oxygen saturation kukusebenzisa i-finger-cuff type photoelectric sensor, kunye ne-oxygen saturation ye-arterial blood saturation isetyenziselwa ukubuyisela i-oxygen saturation yezicubu zomntu.Ukubeka iliso kwi-arterial saturation ye-oksijini yegazi kunokuthwala ioksijini iye kwi-oxyhemoglobin emiphungeni.Ingabonakalisa ngokuthe ngqo umsebenzi wokuphefumula wemiphunga.Ixabiso lomlinganiselo wabantu abasempilweni kufuneka libe ngaphezulu kwama-95%, kwaye linokuba ngaphantsi kwabatshayayo.Ngokuqhelekileyo kuqwalaselwa ukuba ngaphantsi kwe-90% luphawu lwengozi.
Ukuba umthamo weoksijini wegazi womzimba womntu uyancitshiswa, kulula ukubangela iimpawu ezinjengokudinwa nokulala, ukungabikho kwamandla, nokulahlekelwa yinkumbulo.Isiqulatho se-oksijini yegazi ixesha elide siya kubangela umonakalo kwingqondo, intliziyo kunye namanye amalungu.
Ingqondo yeyona ndawo ibuthathaka kakhulu kwi-hypoxia.I-hypoxia ebuchotsheni iya kubangela iimpawu ezifana nokudinwa kwengqondo, ukungakwazi ukugxila, kunye nokulahlekelwa yinkumbulo.Ukuba ingqondo iyaqhubeka ingenayo ioksijini, iya kukhokelela ekufeni kweeseli zemithambo-luvo, kwaye kulula ukuchaphazela ukusebenza kwezinye iinkqubo, ezibeka ubomi esichengeni.Ukuba i-hypoxia iyancipha, okanye i-hypoxia ebukhali, ingqiqo yabantu yendlela kunye nokulungelelaniswa kwemoto iya kulahleka ngokuthe ngcembe, kwaye kwiimeko ezinzima, ukuphazamiseka kwengqondo, i-coma, kunye nokufa kuya kwenzeka.
Njengengqondo, intliziyo lilungu elisebenzisa ioksijini eninzi kwaye linesantya esiphezulu sokutya ukutya.Xa intliziyo iphantsi kwe-hypoxic, izinga lentliziyo elihlawulelwayo liyenyuka kuqala, ukubetha kwentliziyo kunye nokuphuma kwentliziyo kuyanda, inkqubo yokujikeleza kwegazi ihlawulela ukungabikho komxholo we-oksijini kwimeko ye-hyperdynamic, kwaye kwangaxeshanye ivelisa ukuhanjiswa kwegazi kwakhona, i-cerebral and coronary .Ukwandiswa okukhethiweyo ukuqinisekisa ukunikezelwa kwegazi okwaneleyo kuya kubangela iimpawu ezinjengokuphazamiseka kwesigqi sentliziyo kunye nokubetha kwentliziyo.Xa intliziyo iqhubeka ne-hypoxia engapheliyo, ngenxa yokuqokelelwa kwe-subendocardial lactic acid, i-ATP synthesis iyancipha, ibangele ukudakumba kwe-myocardial, okukhokelela kwi-bradycardia, ukuqina kwangaphambi kwexesha, ukuhla koxinzelelo lwegazi kunye nokuphuma kwentliziyo, kunye ne-arrhythmias efana ne-ventricular fibrillation kunye ne-ventricular. iFibrillation.i-asystole.Xa intliziyo i-hypoxic kakhulu, iya kukhokelela kwi-hypertrophy ye-myocardial kunye ne-cardiac volume hypertrophy, ukusebenza kwentliziyo kuya kuncipha, kwaye ukungaphumeleli kwentliziyo kuya kwenzeka lula..
Ukongezelela, uphando oluhambelanayo ngaphandle kwecandelo lezonyango luye lwaqinisekisa ukuba ukubeka iliso kwi-oksijini ye-oksijini yegazi kunokubaluleka okubalulekileyo okukhokelayo ekukhokeleni unyango lwe-cardiovascular disease kunye nokuqikelelwa kwe-prognosis.
Ukuze ugweme ngokufanelekileyo umonakalo ohlukeneyo womzimba obangelwa yi-hypoxia, kubaluleke kakhulu ukubeka iliso kwi-oksijini yegazi kubomi bemihla ngemihla.Ukususela ekuveleni kwendlela yokubeka iliso kwi-oxygen saturation yegazi ukuza kuthi ga ngoku, i-pulse oximeter isetyenziswe ngokubanzi kwi-clinical practice ngenxa yeenzuzo zayo ezingabonakaliyo, ezikhuselekileyo kwaye ezinokwethenjelwa, ezilula ukuyisebenzisa, ezisebenzayo, eziqhubekayo kunye nexesha, kunye nexabiso eliphantsi.Kuye kwaba sisixhobo esibaluleke kakhulu sokuxilongwa kwezonyango kwigumbi likaxakeka, igumbi lokusebenza kunye negumbi lokunyamekela kakhulu esibhedlele.
Ngokomzekelo, kwigumbi likaxakeka, i-monitor ye-oksijeni yegazi inokuqhubeka iliso kwi-oksijini yegazi yesigulane, kwaye emva koko inqume ukunikezelwa kwe-oksijini ngokwexabiso lokuzaliswa kwe-oksijini yegazi, ukwenzela ukuba kuqinisekiswe ukuhanjiswa okukhuselekileyo kunye nempumelelo ye-oksijeni.
Kwigumbi lokusebenza, i-monitor ye-oksijeni yegazi ingakwazi ukulinganisa ngokuqhubekayo i-oxygen saturation, ngokukodwa kwizigulane ezigula kakhulu kunye nokusebenza ngokungena komoya ophantsi, unokukhawuleza ukubonelela nge-oxygen yegazi lomguli ngokukhawuleza, ukwenzela ukuba oogqirha bathathe amanyathelo okuhlangula ahambelanayo ngokukhawuleza.Kwigumbi lokubeka iliso, i-monitor ye-oksijeni yegazi inokuseta izinto ze-alamu ezihambelanayo ngokwemeko ehambelana nayo.Xa isigulane sifunyenwe ukuba sine-apnea, ixabiso eliphantsi le-oxygen saturation yegazi, ukukhawuleza kwentliziyo, ukubetha kwentliziyo ecothayo, njl njl.
Ukongeza, kubaluleke kakhulu ekubekeni iliso kumntwana osanda kuzalwa, ngakumbi ubuthathaka ekuchongweni kwe-hyperoxia okanye i-hypoxemia kwiintsana ezisanda kuzalwa kunye neentsana ezizelwe ngaphambi kwexesha, kwaye emva koko uhlengahlengise ubonelelo lwe-oksijini yezixhobo zobonelelo lweoksijini ngexesha lokwenyani ngokweziphumo zokubeka iliso ukunqanda inkathazo usana olusanda kuzalwa.umonakalo engqondweni, emehlweni, kunye nemiphunga yabantwana.Kwangaxeshanye, ngakumbi nangakumbi ii-oximeters ezinxitywayo zasekhaya ziye zafika kwingqalelo yabantu, kwaye zisetyenziswa ngokubanzi kuxilongo, ukukhangela, ukuzilawula njalo njalo.
Ngokomzekelo, ukubeka esweni imeko ye-oxygen saturation yegazi ngexesha lokuqonda inkqubo yokuphefumla kunye nempilo ye-cardiovascular health, ukwenzela ukufumanisa ukuba banayo i-hypoxemia ngokukhawuleza, ukuze kuthintelwe okanye kuncitshiswe ukufa ngengozi okubangelwa yi-hypoxia.
Ukongezelela, i-oximeter ingasetyenziselwa ukuhlolwa kweengxaki zokugwinya, ukuhlolwa kwe-syndrome ye-apnea yokulala, kunye nokuhlolwa komlinganiselo wegesi yegazi.Okokugqibela, i-oximeter yasekhaya ikwanayo le misebenzi ilandelayo yokuzilawula-efana nesikhokelo sonyango lwe-oksijini, kwaye izigulana ezineengxaki zokuphefumla ezingapheliyo zihlala zikwazi ukuzilawula ekhaya.
Ukongeza, iimonitha ze-oxygen yegazi zikwasetyenziswa ngokubanzi kuphando lwezonyango kunye nezinye iinkalo.Ngokomzekelo, kwisifundo sokulala ukuphefumula i-oxygen saturation, ukubeka iliso kwi-oxygen saturation yegazi kusetyenziselwa ukuxilonga ukuba isigulane sine-apnea syndrome yokulala okanye i-oxygen saturation ebusuku.Ukuhluthwa okuphantsi kunye nezinye iimeko, ukuxilongwa kokugqibela kwesifo esingapheliyo se-tracheal obstructive.
Isenokusetyenziswa kuphando lwempilo yabantu yezemidlalo kwaye idlala indima ebalulekileyo kwezinye iinkalo ezininzi ezifana: nomkhosi, i-aerospace kunye nokunye.Kwixesha elizayo, iimonitha ze-oxygen saturation eziphathwayo ziya kusetyenziswa ngokubanzi kukhathalelo lwempilo yasekhaya kunye nokhathalelo lwempilo yoluntu, oluya kuba lubaluleke kakhulu ekuthinteleni nasekuxilongweni kwezifo zabantu.Kwisicwangciso sophando kunye nophuhliso lwe-oximeter, i-Narigmed, izinikele ekuphuculeni ngokuqhubekayo ukuchaneka komlinganiselo we-oximeter, ngokuqhubekayo ukuphucula ukusebenza okubuthathaka kwe-perfusion kunye nokusebenza okuchasene nokuzivocavoca, kunye nokulindela ukuzisa iindaba ezilungileyo kubantu abaninzi, iteknoloji ye-oksijini yegazi ye-Narigmed inokuzimela. Amalungelo epropathi yobukrelekrele, kunye ne-perfusion ebuthathaka PI = 0.025 % Isenakho ukugcina ukuchaneka kweoksijini yegazi kunye nomlinganiselo wesantya sokubetha kwentliziyo phantsi kwe-ultra-low i-perfusion ebuthathaka kunye nezihlandlo ezithile zentshukumo esisigxina kunye nentshukumo engahleliweyo, ngokungathandabuzekiyo inkokeli phakathi kwezonyango zaseTshayina. iinkampani zezixhobo.
