Amaraso yuzuye ya ogisijeni (SpO2)

SPO2irashobora gucikamo ibice bikurikira: “S” bisobanura kwiyuzuzamo, “P” bisobanura impiswi, naho “O2” bisobanura ogisijeni.Iyi magambo ahinnye yerekana urugero rwa ogisijeni ifatanye na selile ya hemoglobine muri sisitemu yo gutembera kw'amaraso.Muri make, agaciro kerekana urugero rwa ogisijeni itwarwa na selile zitukura.Iki gipimo cyerekana imikorere yumwuka wumurwayi nuburyo bwiza bwo gutembera kwamaraso mumubiri.Umwuka wa ogisijeni ukoreshwa nkijanisha kugirango werekane ibisubizo byiki gipimo.Impuzandengo yo gusoma kubantu basanzwe bafite ubuzima bwiza ni 96%.

Amaraso ya ogisijeni yamaraso apimwa hifashishijwe pulse oximeter, ikubiyemo monitor ya mudasobwa hamwe no gutunga urutoki.Urutoki rushobora gufatirwa ku ntoki z'umurwayi, amano, izuru cyangwa ugutwi.Monitor irerekana isoma ryerekana urugero rwa ogisijeni mumaraso yumurwayi.Ibi bikorwa hakoreshejwe imiraba isobanurwa neza nibimenyetso byumvikana, bihuye numutima wumurwayi.Iyo umwuka wa ogisijeni uri mu maraso ugabanuka, imbaraga z'ikimenyetso ziragabanuka.Monitor irerekana kandi umuvuduko wumutima kandi ifite impuruza, mugihe impiswi yihuta / itinda kandi kwiyuzuza ni hejuru / hasi, ikimenyetso cyo gutabaza gitangwa.

Uwitekaigikoresho cyo kuzuza amaraso ya ogisijeniapima amaraso ya ogisijeni n'amaraso ya hypoxic.Imirongo ibiri itandukanye ikoreshwa mugupima ubu bwoko bubiri bwamaraso: umutuku na infragre.Ubu buryo bwitwa spectrophotometrie.Umuyoboro utukura ukoreshwa mu gupima hemoglobine yanduye, naho inshuro ya infragre ikoreshwa mu gupima amaraso ya ogisijeni.Niba yerekana kwinjiza kwinshi muri bande ya infragre, ibi byerekana kwiyuzuza cyane.Ibinyuranye, niba kwinjirira kwinshi kwerekanwe mumurongo utukura, ibi byerekana kwiyuzuza gake.

Umucyo woherezwa mu rutoki, kandi imirasire yanduye ikurikiranwa nuwakira.Bimwe murumuri byinjizwa nuduce namaraso, kandi iyo imiyoboro yuzuyemo amaraso, iyinjira ryiyongera.Mu buryo nk'ubwo, iyo imiyoboro irimo ubusa, urwego rwo kwinjiza rugabanuka.Kuberako muriyi porogaramu, impinduka yonyine ni pulsating flow, igice gihamye (ni ukuvuga uruhu na tissue) birashobora gukurwa mubarwa.Kubwibyo, ukoresheje uburebure bubiri bwumucyo wakusanyirijwe mu gupima, oximeter ya pulse ibara ubwuzure bwa ogisijeni ya hemoglobine.

Kwiyuzuzamo 97% = 97% umwuka wa ogisijeni igice (gisanzwe)

Kwiyuzuza 90% = 60% umwuka wa ogisijeni igice (akaga)

Kwiyuzuza 80% = 45% byamaraso ya ogisijeni yumuvuduko wigice (hypoxia ikabije)
