I-PI elinganiswa ngeminwe ehlukene nge-pulse oximeter yasendlini inganikeza ukufundwa okuhlukile.Inani eliphakeme kakhulu le-PI lisemunweni ophakathi nendawo.Odokotela kanye nodokotela bokunakekelwa okuyisisekelo kufanele baqaphele umehluko ezilinganisweni ze-PI phakathi kweminwe futhi basebenzise ukufundwa ngokuqapha kunoma yiziphi izinjongo zokuxilonga.
I-Pulse oximetry iyindlela elula kakhulu engahlaseli yokulinganisa ukugcwala komoyampilo wegazi [1].Ama-pulse oximeters aphathekayo, abathengi futhi athengekayo asevele emakethe njengamadivayisi okuqapha impilo yasekhaya [2].Esimweni sasekhaya nasesibhedlela, ama-pulse oximeters avame ukunamathiselwa eminweni futhi ngezinye izikhathi ezindlebeni noma ezinzwaneni.I-probe yemitha iqukethe inzwa ye-photoplethysmographic esiza ukuhlaziya ukumuncwa okuhlobene kwamagagasi abomvu ne-infrared ngokugeleza kwegazi okufakwe umoya-mpilo kanye ne-deoxygenated pulsatile [3].
Ngaphezu kokulinganisa ukugcwala komoyampilo, ama-pulse oximeter ahlinzeka nge-perfusion index (PI).I-PI ingummeleli wesimo se-peripheral perfusion.Isignali ye-pulsatile (ekhiqizwe ukugeleza kwe-arterial) ivezwa njengephesenti lesiginali engaguquki (i-blood stasis) ukubala i-PI [4].Ama-PI asetshenziswa kuzilungiselelo ezihlukahlukene zomtholampilo, okuhlanganisa amayunithi okunakekelwa okujulile, ukuqapha isikhathi sokuhlinzwa ngesikhathi sokuhlinzwa, kanye nokuvinjelwa kwe-stellate ganglion ukukala ukusebenza kwabo [5-7].
Ucwaningo lwangaphambili olwenziwa nguSapra et al.Phakathi kwabasebenzi bezokwelapha, i-PI ephakeme kakhulu umunwe wendandatho yesandla sokudla, futhi ephansi kunazo zonke isithupha sesandla sokudla [8].Ngokuphambene, i-Tripathy et al.Kuye kwaboniswa ukuthi i-PI elinganiswa eminweni ehlukene ihlukile, inenani eliphakeme kakhulu lomunwe ophakathi nendawo kanye nenani eliphansi kakhulu lomunwe omncane [9].Kodwa-ke, ngokwazi kwethu, azikho izifundo ezithole ubuqiniso bezilinganiso ze-PI ngeminwe yonke.
Kulo mongo, lolu cwaningo lwaluhlose ukuqhathanisa i-PI yeminwe yezandla zombili kubantu ngokusobala abanempilo.Imiphumela yalolu cwaningo izosiza ukuthola ukuhlukahluka nokuba semthethweni kwamanani e-PI akalwa phakathi kweminwe ehlukene kusetshenziswa i-pulse oximetry.Ngokusekelwe emiphumeleni, odokotela bokunakekelwa okuyinhloko banganquma ukuthi i-PI elinganiswa nge-oximeter ephathekayo ingasetshenziswa yini ukuthola ukuchithwa okungalungile.

Ukuhlobana phakathi kweminwe emaphakathi kwesokunxele nakwesokudla bekungu-0.287 (CI 0.193 kuya ku-0.375; p<0.0001).Ukuhlobana nomugqa wethrendi kuboniswa esakhiweni sokuhlakazeka kuMfanekiso 5.
I-ICC yabo bonke, iminwe yesokudla nesobunxele yayingu-0.474, 0.368, kanye no-0.635 (Ithebula 4), ebonisa ukwethembeka kwesilinganiso "sokumpofu", "esimpofu", kanye "nokulinganisela", ngokulandelana.
Ngokusho kwedatha, i-ICC Model 3 isetshenziswe nokokufaka kwe-SPSS njengemodeli "ehlangene ezinhlangothini ezimbili" kanye nohlobo "oluhambisana ngokuphelele".
Ngokuphathelene nokulingana phakathi kwama-PI akalwa ngeminwe engu-10, sithole umehluko omkhulu phakathi kwezilinganiso.Umunwe ophakathi ubonisa i-PI ephezulu kakhulu elinganiswa phakathi kweminwe yesandla.Nakuba ukuhlobana phakathi kwe-PI yeminwe emaphakathi nesobunxele nekwesokudla kwakubalulekile ngokwezibalo, i-coefficient of determination (r2) ibonise ukuthi cishe u-8% wezinguquko ku-PI yomunwe ophakathi kwesokunxele zingabikezelwa kusukela kumunwe ophakathi kwesokudla futhi ngokuphambene nalokho [ 16].
I-PI ibalwa kusukela kusignali ye-photoplethysmography ngokuqhathanisa ukujikeleza kwe-peripheral okunamaphaphu nokungaphumi.Izici ezimbili ezinkulu zingathonya i-PI, ukuphuma kwenhliziyo, kanye nebhalansi phakathi kwesistimu yezinzwa ezinozwela kanye ne-parasympathetic.
I-PI iphezulu uma ukuphuma kwenhliziyo kuphezulu kanye/noma i-parasympathetic igcwele.Ngokuphambene, i-PI iphansi lapho ukuphuma kwenhliziyo kuphansi futhi/noma ukuzwela kugcwele.Ibanga elijwayelekile le-PI lithathwa njengelisuka ku-0.2% liye ku-20% [17].Ocwaningweni lwethu, sithole i-PI engu-4.37 ± 2.07% yomunwe omaphakathi kwesokunxele kanye no-4.66 ± 2.18% womunwe ophakathi kwesokudla.Kodwa-ke, asizange silinganise ukukhishwa kwenhliziyo kanye nesistimu yezinzwa ezizimele ukuze siphawule ngezimo ezifanele zenhliziyo nesistimu yezinzwa.Imiphumela yethu iqinisekisa idatha ye-Savastan et al.Ngokusobala abantu abaphilile abaneminyaka yobudala engama-42 (ububanzi be-interquartile = 33-47) babene-PI ye-4.3 (ububanzi be-interquartile = 2.9-6.2) [18].
Esimeni sokuphila, ukuma kuthinta i-PI elinganisiwe, etholakale iphansi kakhulu endaweni yokuhlala futhi ephakeme kakhulu endaweni ye-Tendelenburg [11].Esifundweni sethu, sisebenzise indawo yokuhlala kubo bonke ababambiqhaza.Ngakho-ke, uma siqhathanisa eminwe, sicabanga ukuthi i-PI isezingeni eliphansi kakhulu.Ngenxa yokuthi i-PI iyisilinganiso sokugeleza kwegazi okuphuphumayo nokungashunqisi, noma yisiphi isifo esiphazamisa ukugeleza kwegazi okuzungezile sithinta i-PI [19].I-PI emnyangweni ophuthumayo isiza ukucacisa isidingo sokumpontshelwa igazi [20].Kuyasiza futhi ukuhlola ingozi yokufa ezigulini ezinokopha okuphezulu kwamathumbu kanye neziguli ezinomshini wokuphefumula [21,22].Ngaphezu kwalokho, kusiza ukuthola i-hypotension ngesikhathi sokubulala izinzwa futhi kunqume ukusebenza kwe-ganglionic blockades [6,7].Esimweni sokunakekelwa okujulile, i-pulse oximeter iyingxenye ebalulekile yokuqapha amanye amapharamitha endaweni eyodwa yezinga lesibhedlela.Kodwa-ke, kulolu cwaningo, sisebenzise amadivayisi asezingeni lomthengi.Ngakho-ke, imiphumela yalolu cwaningo ingase ingafaniswa nezifundo ezisebenzisa ama-oximeter ebanga lasesibhedlela.
I-Consumer grade pulse oximeters ingasetshenziswa odokotela abanakekela okuyinhloko kanye nabelaphi abavamile ekuvakasheni kwasekhaya ukukala ukugcwala komoyampilo wesiguli (SpO2) kanye ne-PI.Kufanele bathathe izinyathelo zokuphepha ukuze banciphise ukudluliswa kwalesi sifo phakathi kweziguli zisebenzisa ama-probe noma iminwe [23].Kodwa-ke, kufanele baqaphele njengoba i-PI ilinganiswa ngeminwe ehlukene inganikeza ukufundwa okuhlukile.Ucwaningo lwangaphambilini lubonise ukuthi umunwe ophakathi ubonisa amazinga aphezulu e-SpO2 uma kuqhathaniswa neminye iminwe [24,25].Kulolu cwaningo, sithole ukuthi i-PI iphinde yakhombisa amaphuzu aphezulu emunweni ophakathi nazo zombili izitho.
Lolu cwaningo lunokulinganiselwa okuthile.Saqoqa amasampula ukuze senze ucwaningo esibhedlela.Amasampula alula amasampula anethuba eliphansi.Ngakho-ke, akunakwenzeka ukuhlola ukuthi umele kahle kangakanani abantu.Ngaphezu kwalokho, siqoqe kuphela amasampula kubantu ababonakala bephilile ukuze sinqume i-PI ngaphansi kwezimo ezijwayelekile zomzimba.Ngakho-ke, imiphumela ingase ingasebenzi kubantu abananoma yisiphi isimo sezokwelapha.
Ama-oximeter we-pulse ephathekayo nasendlini angakala i-PI ngendlela ehlukile eminweni ehlukene yesandla sobunxele nakwesokudla.Amanani aphezulu we-PI atholwe emunweni ophakathi wesandla ngasinye.Ukuthembeka kwe-PI kukalwa nge-pulse oximeter eminweni ehlukene kuphansi.Ngakho-ke, i-PI etholwe nge-oximeter kufanele ihunyushwe ngokuqapha nganoma iyiphi injongo yokuxilonga.Ucwaningo olwengeziwe luyadingeka ukuze kuqhathaniswe ukwethembeka kwesibhedlela kanye nama-oximeter omthengi ekulinganiseni i-PI yeminwe ehlukene.
