I-pulse oximeter sisixhobo esisetyenziselwa ukulinganisa i-arterial oxygen saturation kwisigulane.Isebenzisa umthombo wokukhanya obandayo okhanya ngencam yomnwe.Emva koko ihlalutya ukukhanya ukumisela ipesenteji yeoksijini kwiiseli ezibomvu zegazi.Isebenzisa olu lwazi ukubala ipesenti yeoksijini esegazini lomntu.Kukho iintlobo ezininzi ze-pulse oximeters.Nantsi inkcazo ekhawulezayo yeziseko ze-pulse oximeters.
I-Pulse oximeters isetyenziswa ngabasebenzi bezempilo ukujonga amanqanaba e-oxygen yesigulana.Xa inqanaba le-oksijini yesigulana lisezantsi, oko kuthetha ukuba izicubu kunye neeseli aziyifumani ioksijini eyaneleyo.Izigulana ezinamaqondo aphantsi oksijini zinokuphefumla kancinci, ukudinwa, okanye intloko ebuhlungu.Le meko iyingozi kwaye ifuna unyango.Inokwenzeka nakubantu abaneemeko zempilo eziphantsi.I-oximeter sisixhobo esibalulekileyo sokubeka iliso kumanqanaba akho oksijini kwaye uxele naluphi na utshintsho kugqirha wakho okanye kumboneleli wezempilo.
Enye into enokuchaphazela ukuchaneka kweziphumo ze-pulse oximeter ngumsebenzi womntu.Ukuzilolonga, ukuxhuzula, kunye nokungcangcazela konke kunokukhupha inzwa ekunyukeni kwayo.Ukufundwa okungalunganga kunokubangela amanqanaba aphantsi eoksijini emzimbeni anokuthi angabonakali ngoogqirha.Ngaloo ndlela, kubalulekile ukuqonda imida ye-pulse oximeter ngaphambi kokuba uyisebenzise.
Kukho iintlobo ezininzi ezahlukeneyo ze-pulse oximeters.Elungileyo yileyo ekulula ukuyisebenzisa kwaye inokubeka iliso kubantu abaninzi ekhaya.Xa ukhetha i-pulse oximeter, khangela umboniso "we-waveform", obonisa izinga lokubetha.Olu hlobo lokubonisa lunceda ukuqinisekisa ukuba iziphumo zichanekile kwaye zithembekile.Ezinye ii-oximeters ze-pulse nazo zinexesha elibonisa ukubetha kwentliziyo.Oku kuthetha ukuba unako ixesha lokufunda kwi-pulse yakho ukuze ufumane ezona ziphumo zichanekileyo.
Kukho nemida ekuchanekeni kwe-pulse oximeters kubantu bemibala.I-FDA ikhuphe isikhokelo malunga nokungeniswa kwangaphambili kwi-premarket yokusetyenziswa kwe-oximeters.I-arhente incoma ukuba iimvavanyo zeklinikhi kufuneka zibandakanye abathathi-nxaxheba abaneentlobo ezahlukeneyo ze-pigmentation yesikhumba.Umzekelo, ubuncinci abathathi-nxaxheba ababini kuphononongo lweklinikhi kufuneka babe nesikhumba esimnyama.Ukuba oku akunakwenzeka, ngoko ke uphononongo lunokufuneka luhlolwe kwakhona, kwaye umxholo woxwebhu lwesikhokelo unokutshintsha.
Ukongeza ekufumaneni i-COVID-19, i-pulse oximeters inokuchonga ezinye iimeko ezichaphazela amanqanaba eoksijini.Izigulana ezine-COVID-19 azikwazi ukuvavanya iimpawu zazo kwaye zinokuba ne-hypoxia ethe cwaka.Xa oku kusenzeka, amanqanaba eoksijini ehla ngokuyingozi kwaye isigulana asinakuxela ukuba sine-COVID.Le meko isenokufuna nesixhobo sokungenisa umoya ukuze siphile.Isigulana kufuneka sibekwe iliso elibukhali, njengoko i-hypoxia ethe cwaka inokukhokelela kwinyumoniya enxulumene ne-COVID-19.
Enye inzuzo ebalulekileyo ye-pulse oximeter yinto yokuba ayifuni iisampuli zegazi.Isixhobo sisebenzisa iiseli ezibomvu zegazi ukulinganisa i-oxygen saturation, ngoko ukufundwa kuya kuchaneka kakhulu kwaye ngokukhawuleza.Uphononongo oluqhutywe kwi-2016 lubonise ukuba izixhobo ezingabizi ziyakwazi ukubonelela ngeziphumo ezifanayo okanye ezingcono njengesixhobo esivunywe yi-FDA.Ngoko ukuba unenkxalabo malunga nokuchaneka kokufunda, unganqikazi ukubuza ugqirha wakho.Okwangoku, qiniseka ukusebenzisa i-pulse oximeter kwaye ufumane ulwazi oludingayo.Uya kuvuya ngokuba wenzile.
I-pulse oximeter ibaluleke kakhulu kubantu abane-COVID-19 kuba ibavumela ukuba babeke iliso kwimeko yabo kwaye baqinisekise ukuba bayalufuna na unyango.Nangona kunjalo, i-pulse oximeter ayithethi lonke ibali.Ayilinganisi inqanaba leoksijini egazini lomntu kuphela.Ngapha koko, inqanaba leoksijini elilinganiswe yi-pulse oximeter linokuba lisezantsi kwabanye abantu kodwa baziva beqhelekile ngokugqibeleleyo ngelixa amanqanaba eoksijini esezantsi.
Uphononongo lwafumanisa ukuba i-pulse oximeters enxibayo inokunceda izigulana ziqonde amanqanaba e-oxygen yegazi.Enyanisweni, zinengqondo kangangokuba zamkelwa ngokubanzi ngaphambi kokuba ulingo lwenziwe.Ziye zasetyenziswa kwiinkqubo ezahlukeneyo zempilo, kubandakanywa izibhedlele kunye neenkqubo zempilo kumazwe afana neVermont kunye ne-United Kingdom.Abanye bade baba zizixhobo zonyango ezisetyenziswa rhoqo kubaguli emakhayeni abo.Ziluncedo kuxilongo lwe-COVID-19 kwaye ziye zasetyenziswa kulawulo lokhathalelo lwasekhaya.
