Qhov koj cov ntshav oxygen qib qhia tau li cas
Ntshav oxygen yog ib qho kev ntsuas seb cov qe ntshav liab nqa oxygen ntau npaum li cas. Koj lub cev zoo tswj cov pa oxygen hauv koj cov ntshav. Kev tswj hwm qhov sib npaug ntawm cov pa oxygen txaus hauv koj cov ntshav yog qhov tseem ceeb rau koj txoj kev noj qab haus huv.
Cov menyuam yaus thiab cov neeg laus feem ntau tsis tas yuav saib xyuas lawv cov ntshav oxygen. Qhov tseeb, ntau tus kws kho mob yuav tsis kuaj nws tshwj tsis yog tias koj tab tom pom cov tsos mob ntawm qhov teeb meem, xws li ua pa luv lossis mob hauv siab.
Txawm li cas los xij, cov neeg uas muaj mob ntev ntau yuav tsum tau saib xyuas lawv cov ntshav oxygen. Qhov no suav nrog mob hawb pob, kab mob plawv, thiab mob ntsws obstructive pulmonary (COPD).
Hauv cov xwm txheej no, kev saib xyuas koj cov ntshav oxygen tuaj yeem pab txiav txim siab seb cov kev kho mob puas ua haujlwm, lossis lawv yuav tsum tau kho.
Kev ntsuas koj cov ntshav oxygen npaum li cas
Koj cov ntshav oxygen qib tuaj yeem ntsuas nrog ob qhov kev ntsuas sib txawv:
Arterial ntshav roj
Kev kuaj ntshav ntshav ntshav (ABG) yog kuaj ntshav. Nws ntsuas koj cov ntshav qib oxygen. Nws kuj tuaj yeem kuaj xyuas qib ntawm lwm cov roj hauv koj cov ntshav, nrog rau pH (acid / base level). Ib qho ABG yog qhov tseeb heev, tab sis nws yog invasive.
Yuav kom tau txais kev ntsuas ABG, koj tus kws kho mob yuav kos cov ntshav los ntawm cov hlab ntsha es tsis yog cov hlab ntsha. Tsis zoo li cov hlab ntsha, cov hlab ntsha muaj cov mem tes uas tuaj yeem hnov. Tsis tas li ntawd, cov ntshav los ntawm cov hlab ntsha yog oxygenated. Ntshav hauv koj cov leeg tsis yog.
Cov hlab ntsha hauv koj lub dab teg yog siv vim nws yooj yim xav piv rau lwm tus hauv koj lub cev.
Lub dab teg yog ib qho chaw rhiab heev, ua rau cov ntshav ntws tsis zoo dua piv rau cov leeg nyob ze koj lub luj tshib. Cov hlab ntsha kuj tseem tob dua cov hlab ntsha, ntxiv rau qhov tsis xis nyob.
Pulse oximeter
A pulse oximeter (mem tes ox) yog ib yam khoom uas tsis muaj kev cuam tshuam uas kwv yees cov pa oxygen hauv koj cov ntshav. Nws ua li ntawd los ntawm kev xa lub teeb infrared mus rau hauv capillaries hauv koj tus ntiv tes, ntiv taw, lossis pob ntseg. Tom qab ntawd nws ntsuas ntau npaum li cas lub teeb pom kev tawm ntawm cov pa roj.
Kev nyeem ntawv qhia tias feem pua ntawm koj cov ntshav yog saturated, hu ua SpO2 qib. Qhov kev sim no muaj 2 feem pua qhov yuam kev. Qhov ntawd txhais tau hais tias kev nyeem ntawv yuav ntau npaum li 2 feem pua siab dua lossis qis dua koj cov ntshav oxygen.
Qhov kev sim no yuav tsis tshua muaj tseeb, tab sis nws yooj yim heev rau cov kws kho mob ua. Yog li cov kws kho mob tso siab rau nws rau kev nyeem ntawv ceev.
Vim hais tias ib tug pulse ox yog noninvasive, koj tuaj yeem ua qhov kev sim no koj tus kheej. Koj tuaj yeem yuav cov khoom siv pulse ox ntawm ntau lub khw muag khoom uas nqa cov khoom lag luam ntsig txog kev noj qab haus huv lossis hauv online.
