Koj cov ntshav oxygen qib qhia li cas
Koj cov ntshav oxygen qib yog ntsuas seb koj cov ntshav liab nqa oxygen npaum li cas.Koj lub cev nruj tswj cov pa oxygen hauv koj cov ntshav.Ua kom muaj qhov sib npaug ntawm cov ntshav oxygen saturation 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, tshwj tsis yog tias koj pom cov teeb meem xws li ua tsis taus pa lossis mob hauv siab, ntau tus kws kho mob yuav tsis kuaj nws.
Txawm li cas los xij, ntau tus neeg uas muaj kab mob ntev 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 cov pa oxygen tuaj yeem pab txiav txim siab seb kev kho mob puas zoo lossis puas yuav tsum tau kho.
Nyeem rau kom paub seb qhov twg cov ntshav oxygen yuav tsum nyob, cov tsos mob dab tsi koj yuav pom yog tias cov ntshav oxygen qis qis, thiab yuav tshwm sim li cas ntxiv.
Arterial ntshav roj
Kev kuaj ntshav arterial blood gas (ABG) yog kuaj ntshav.Nws tuaj yeem ntsuas cov ntsiab lus oxygen hauv cov ntshav.Nws tseem tuaj yeem kuaj xyuas qib ntawm lwm cov pa roj hauv cov ntshav thiab pH (acid / base level).ABG yog qhov tseeb heev, tab sis nws yog invasive.
Yuav kom tau txais qhov ntsuas ABG, koj tus kws kho mob yuav kos cov ntshav los ntawm cov hlab ntsha es tsis txhob siv 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 oxidized.Ntshav tsis yog.
Cov hlab ntsha ntawm lub dab teg yog siv vim nws yooj yim rau kev xav piv rau lwm cov hlab ntsha hauv lub cev.
Lub dab teg yog qhov chaw rhiab heev uas ua rau cov ntshav nyob ntawd tsis xis nyob dua li cov leeg nyob ze ntawm lub luj tshib.Cov hlab ntsha kuj tseem tob dua cov hlab ntsha, uas ua rau muaj kev tsis xis nyob
Qhov twg cov ntshav oxygen qib yuav tsum poob
Tus nqi ntawm cov pa oxygen hauv cov ntshav yog hu ua oxygen saturation.Hauv kev kho mob luv luv, PaO 2 yuav hnov thaum siv cov roj ntshav, thiab O 2 zaum (SpO2) yuav hnov thaum siv nyuj pulsed.Cov lus qhia no yuav pab koj nkag siab tias cov txiaj ntsig yuav txhais li cas:
Ib txwm: Cov ntsiab lus ABG oxygen ib txwm ntawm lub ntsws noj qab haus huv yog nyob nruab nrab ntawm 80 mmHg thiab 100 mmHg.Yog tias tus nyuj pulse ntsuas koj cov ntshav oxygen (SpO2), qhov kev nyeem ntawv ib txwm nyob ntawm 95% thiab 100%.
Txawm li cas los xij, hauv COPD lossis lwm yam kab mob ntsws, cov kab no yuav tsis siv tau.Koj tus kws kho mob yuav qhia koj tias dab tsi yog qhov qub rau ib qho xwm txheej.Piv txwv li, nws tsis yog qhov tsis yooj yim rau cov neeg uas muaj COPD hnyav los tswj lawv cov qib pulse oxygen (SpO2) ntawm 88% thiab 92% kev ntseeg siab.
Tsawg dua li qub: Cov ntshav oxygen qis dua li qub yog hu ua hypoxemia.Hypoxemia feem ntau ua rau muaj kev txhawj xeeb.Qhov qis dua cov ntsiab lus oxygen, qhov hnyav dua qhov hypoxemia.Qhov no tuaj yeem ua rau muaj teeb meem hauv cov ntaub so ntswg hauv lub cev thiab lub cev.
Feem ntau, PaO 2 nyeem qis dua 80 mm Hg lossis pulse OX (SpO2) qis dua 95% yog suav tias yog qis.Nws yog ib qho tseem ceeb kom nkag siab txog koj tus mob ib txwm, tshwj xeeb tshaj yog tias koj muaj kab mob ntsws ntev.
Koj tus kws kho mob tuaj yeem qhia koj txog qhov ntau ntawm cov pa oxygen uas koj tuaj yeem txais.
Tshaj li qhov qub: Yog tias ua pa nyuaj, nws nyuaj rau muaj oxygen ntau dhau.Feem ntau, cov neeg uas muaj cov pa oxygen ntxiv yuav muaj cov pa oxygen siab.Yuav kuaj tau ntawm ABG.
