PULSE oximetry mubyukuri irashobora kubara arterial hemoglobine ya ogisijeni yuzuye kuva ku kigereranyo cya pulsatile n'umucyo utukura wose wanduye ugabanijwe ku kigereranyo kimwe cy'urumuri rutagira ingano rutanga urutoki, ugutwi, cyangwa izindi ngingo.Kwiyuzuza gukomokaho bigomba kuba bitiganjemo pigmentation yuruhu, nibindi byinshi bihinduka, urugero nka hemoglobine yibanze, imisumari yimisumari, umwanda, na jaundice.Ubushakashatsi bwinshi bunini bwagenzuwe bugereranya abarwayi b'abirabura n'abazungu (amasomo 380) 1,2 bavuze ko nta makosa akomeye ajyanye na pigment muri oximeter ya pulse yuzuye.
Icyakora, Severinghaus na Kelleher3 basuzumye amakuru yakozwe nabashakashatsi benshi bari baragaragaje amakosa ya anecdotal (+3 kugeza + 5%) ku barwayi b'abirabura.4–7 Icyitegererezo cy'amakosa kubera pigment zitandukanye cyasuzumwe na Ralston.n'abandi.8 Coten'abandi.9 yatangaje ko imisumari na wino hejuru yuruhu bishobora gutera amakosa, ubushakashatsi bwashimangiwe nabandi bivuye kuri wino yo gutunga urutoki, hina 10, 11 na meconium.12 Irangi ryatewe mumitsi ritera amakosa yinzibacyuho.13 Leen'abandi.14 basanze gukabya guhaga, cyane cyane ku kwiyuzuza gake ku barwayi bafite pigment (Umuhinde, Maleziyav.Igishinwa).Komite ishinzwe ikoranabuhanga mu itsinda ry’imirimo ishinzwe ubuvuzi bukomeye, Minisiteri y’ubuzima ya Ontario, 15 yatangaje ko amakosa atemerwa muri pulse oximetry yuzuye yuzuye mu masomo ya pigment.Zeballos na Weisman16 bagereranije ukuri kwa oximeter ya Hewlett-Packard (Sunnyvale, CA) na oximeter ya Biox II (Ohmeda, Andover, MA) mu basore 33 b'abirabura bakora imyitozo ku butumburuke butatu butandukanye.Ku butumburuke bwa m 4000, aho kwiyuzuza ogisijeni ya arterial (Sao2) kuva kuri 75 kugeza kuri 84%, Hewlett-Packard yasuzuguye Sao2by 4.8 ± 1,6%, mu gihe Biox yasuzuguye Sao2by 9.8 ± 1.8% (n = 22).Byavuzwe ko aya makosa, yavuzwe mbere mu bazungu, bombi bakabije mu birabura.
Mugihe cyimyaka myinshi yo kugerageza impiswi ya oxyde yuzuye kuri ogisijeni yuzuye munsi ya 50%, twagiye tubona rimwe na rimwe kubogama kwiza bidasanzwe, cyane cyane kurwego rwo kwiyuzuzamo cyane, muri bimwe ariko ntabwo biri mubindi bintu byimbitse.Iperereza rero ryakozwe kuburyo bwihariye kugirango hamenyekane niba amakosa kuri Sao2correlate nkeya afite ibara ryuruhu.
Imisemburo ya oxyde yose yagurishijwe muri Reta zunzubumwe zamerika irasabwa n’ubuyobozi bushinzwe ibiryo n’ibiyobyabwenge muri Amerika ko byapimwe kandi bikemezwa ko ari ukuri kugeza munsi ya ± 3% umuzi bivuze ikosa rya kare kuri Sao2values hagati ya 70 na 100%.Umubare munini wibizamini bya kalibrasi no kwemeza byakorewe mubukorerabushake bafite uruhu rworoshye.
Ubuyobozi bushinzwe ibiryo n'ibiyobyabwenge buherutse gutanga igitekerezo ko ubushakashatsi bwakozwe na pulse oximeter yukuri yatanzwe kugirango yemererwe kugenzura ibikoresho by’ibiribwa n’ibiyobyabwenge birimo ingingo zifite ibara ryinshi ry’uruhu, nubwo nta bisabwa bitangwa.Ntabwo tuzi ko nta makuru ashyigikira iki gikorwa.
Niba haribintu byiza kandi byororoka bibogamye kubwuzuye bwuzuye mubintu byijimye byijimye, gushyiramo amasomo yijimye yijimye bizongera itsinda ryibizamini bivuze imizi bivuze amakosa ya kare, wenda bihagije kugirango banze kwangwa nubuyobozi bushinzwe ibiryo nibiyobyabwenge.Niba kubogama kubyara biboneka kubwuzuye mukintu cyijimye cyijimye muri oximeter zose, ibimenyetso byo kuburira bigomba guhabwa abakoresha, byashoboka nibitekerezo byo gukosora.
