Impanuka ya oximetry

Pulse oximetry nuburyo budashoboka bwo kugenzura ubwuzure bwa ogisijeni yumuntu (SO2).Nubwo isomwa ryayo ryuzuye rya ogisijeni ya periferique (SpO2) ntabwo rihora rihwanye nogusoma kwifuzwa cyane kwuzuza arterial ogisijeni (SaO2) uhereye kubisesengura rya gaz ya arterial, byombi bifitanye isano bihagije kuburyo uburyo bwizewe, bworoshye, budashoboka, buhendutse bwa pulse oximetry. ni ingirakamaro mu gupima kwiyuzuza ogisijeni mu gukoresha ivuriro.

Muburyo busanzwe bukoreshwa (transmissive), igikoresho cya sensor gishyirwa mugice gito cyumubiri wumurwayi, mubisanzwe urutoki cyangwa urutoki, cyangwa mugihe cyuruhinja, hejuru yamaguru.Igikoresho kinyuza imirongo ibiri yumucyo unyuze mugice cyumubiri kuri fotodetekeri.Ipima ihinduka ryimiterere kuri buri burebure bwumuraba, bikayemerera kumenya iyinjizwa ryatewe namaraso yimitsi ya arterial yonyine, ukuyemo amaraso yimitsi, uruhu, amagufwa, imitsi, ibinure, na (akenshi) imisumari yimisumari.

Impinduka ya pulse oximetry nuburyo busanzwe busanzwe bwo kwanduza impiswi.Ubu buryo ntabwo busaba igice cyoroshye cyumubiri wumuntu bityo rero kikaba gikwiranye no gukoreshwa kwisi yose nkibirenge, agahanga, nigituza, ariko kandi bifite aho bigarukira.Vasodilation hamwe no guhuriza hamwe amaraso yimitsi mumutwe kubera kugaruka kwimitsi yangiritse kumutima birashobora gutera guhuza imitsi ya arterial na venine mu karere ka ruhanga kandi biganisha kuri SpO2 ibisubizo bidasanzwe.Ibihe nkibi bibaho mugihe barimo gutera anesthesia hamwe na endotracheal intubation hamwe no guhumeka imashini cyangwa kubarwayi bari mumwanya wa Trendelenburg.
