Yuav ua li cas lub cev tswj cov qib SpO2 li qub?Kev tswj cov ntshav oxygen saturation yog qhov tseem ceeb los tiv thaiv hypoxia.Hmoov zoo, lub cev feem ntau ua qhov no ntawm nws tus kheej.Txoj kev tseem ceeb tshaj plaws rau lub cev kom noj qab haus huvSpO2theem yog los ntawm kev ua pa.Lub ntsws nqus cov pa oxygen uas tau nqus tau thiab khi rau hemoglobin, thiab tom qab ntawd hemoglobin kis tau los ntawm lub cev nrog oxygen.Thaum lub cev muaj zog siab (xws li nqa qhov hnyav lossis khiav) thiab qhov siab dua, lub cev xav tau oxygen nce ntxiv.Tsuav lawv tsis dhau heev, lub cev feem ntau tuaj yeem hloov kho rau cov kev nce no.
Ntsuas cov ntshav oxygen saturation
Muaj ntau txoj hauv kev los kuaj ntshav kom paub tseeb tias nws muaj cov pa oxygen li qub.Txoj kev siv ntau tshaj plaws yog siv lub pulse oximeter los ntsuas SpO2 qib hauv cov ntshav.Pulse oximeters yog ib qho yooj yim siv thiab muaj nyob rau hauv cov tsev kho mob thiab tsev neeg.Txawm hais tias lawv cov nqi qis, lawv yog qhov tseeb heev.Txhawm rau siv lub pulse oximeter, cia li tso rau ntawm koj tus ntiv tes.Ib feem pua yuav tshwm rau ntawm qhov screen.Qhov feem pua yuav tsum nyob nruab nrab ntawm 94% thiab 100%, uas qhia tau tias hemoglobin uas thauj cov pa oxygen los ntawm cov ntshav yog nyob rau theem noj qab haus huv.Yog tias nws tsawg dua 90%, koj yuav tsum mus ntsib kws kho mob.
Lub pulse oximeter ntsuas cov pa oxygen hauv cov ntshav li cas
Lub pulse oximeter siv lub teeb sensor los sau cov ntshav nqa oxygen ntau npaum li cas thiab cov ntshav tsis nqa oxygen.Oxygen-saturated hemoglobin zoo li liab qab rau qhov muag liab qab dua li cov tsis muaj oxygen-saturated hemoglobin.Qhov tshwm sim no ua rau lub siab rhiab heev ntawm pulse oximeter txhawm rau txheeb xyuas cov kev hloov pauv me me hauv cov ntshav thiab hloov mus rau hauv kev nyeem ntawv.
Muaj ntau ntau cov tsos mob ntawm hypoxemia.Tus naj npawb thiab qhov hnyav ntawm cov tsos mob no nyob ntawm qib ntawmSpO2.Tsawg hypoxemia tuaj yeem ua rau qaug zog, kiv taub hau, loog, thiab tingling hnov hauv cov ceg thiab xeev siab.Tshaj li qhov no, hypoxemia feem ntau ua hypoxic.
Cov qib SpO2 li qub yog qhov tseem ceeb rau kev tswj xyuas kev noj qab haus huv ntawm txhua cov ntaub so ntswg hauv lub cev.Raws li tau hais ua ntej, hypoxemia yog qis oxygen saturation hauv cov ntshav.Hypoxemia yog ncaj qha ntsig txog hypoxia, uas yog qhov tsis tshua muaj oxygen saturation hauv tib neeg cov ntaub so ntswg.Yog tias cov ntsiab lus oxygen tsawg heev, hypoxemia feem ntau ua rau hypoxia, thiab nws tseem nyob hauv lub xeev no.Ntshav liab-liab yog qhov qhia tau zoo ntawm hypoxemia ua hypoxic.Txawm li cas los xij, nws tsis yog kev ntseeg siab kiag li.Piv txwv li, cov neeg uas muaj tawv nqaij tawv yuav tsis muaj qhov pom tseeb ntshav osis.Thaum hypoxia ua hnyav dua, ntshav yan syndrome feem ntau tsis ua kom pom kev zoo.Txawm li cas los xij, lwm cov tsos mob ntawm hypoxia ua hnyav dua.Kev mob hypoxia tuaj yeem ua rau qaug zog, tsis meej pem, hnov lus, pallor, lub plawv dhia tsis xwm yeem thiab tuag thaum kawg.Hypoxia feem ntau ua rau cov nyhuv snowball, vim hais tias ib zaug cov txheej txheem pib, nws nrawm dua thiab mob hnyav dua.Ib txoj cai zoo ntawm tus ntiv tes xoo yog tias sai li sai tau thaum koj cov tawv nqaij pib ua xim xiav, koj yuav tsum nrhiav kev pab tam sim ntawd.
