Pulse oximetry yog ib qho kev sim uas tsis muaj kev cuam tshuam thiab tsis mob uas ntsuas cov pa oxygen (lossis qib oxygen saturation) hauv cov ntshav.Nws tuaj yeem tshawb xyuas sai npaum li cas cov pa oxygen xa mus rau cov ceg ceg (xws li ob txhais ceg thiab caj npab) nyob deb tshaj plaws ntawm lub plawv.
A mem tes oximeteryog ib qho khoom siv me me uas tuaj yeem txuas rau lub cev xws li ntiv tes, ntiv taw, pob ntseg thiab hauv pliaj.Nws feem ntau yog siv hauv chav xwm txheej ceev lossis cov chaw saib xyuas mob hnyav xws li tsev kho mob, thiab qee tus kws kho mob yuav siv nws los ua ib feem ntawm kev kuaj mob niaj hnub hauv chaw ua haujlwm.
Tom qab lub pulse oximeter tau teeb tsa rau ntawm lub cev, lub teeb me me ntawm lub teeb hla los ntawm cov ntshav los ntsuas cov ntsiab lus oxygen.Nws ua qhov no los ntawm kev ntsuas kev hloov pauv hauv lub teeb nqus hauv cov ntshav oxygenated lossis deoxygenated ntshav.Lub pulse oximeter yuav qhia koj txog koj cov ntshav oxygen saturation qib thiab lub plawv dhia.
Thaum ua pa nyuaj thaum pw tsaug zog (hu ua qhov tshwm sim apnea lossis SBE) (raws li tuaj yeem tshwm sim hauv obstructive pw tsaug zog apnea), qib oxygen hauv cov ntshav yuav poob ntau zaus.Raws li peb txhua tus paub, kev poob qis hauv cov pa oxygen mus sij hawm ntev thaum pw tsaug zog tuaj yeem ua rau muaj ntau yam teeb meem kev noj qab haus huv, xws li kev nyuaj siab, kab mob plawv, ntshav siab, ntshav qab zib, thiab lwm yam.
Feem ntau, koj tus kws kho mob yuav xav ntsuas koj cov ntshav oxygen qib nrog pulse oximeter,
1. Thaum lub sij hawm los yog tom qab phais los yog txheej txheem siv sedatives
2. Txheeb xyuas tus neeg lub peev xwm los tswj cov qib kev ua ub no ntxiv
3. Tshawb xyuas seb tus neeg twg tsis ua pa thaum pw tsaug zog (pw tsaug zog apnea)
Pulse oximetry kuj tseem siv los kuaj xyuas kev noj qab haus huv ntawm cov neeg muaj kab mob uas cuam tshuam rau cov ntshav oxygen, xws li mob plawv, plawv tsis ua hauj lwm, mob ntsws obstructive pulmonary disease (COPD), anemia, mob ntsws cancer thiab mob hawb pob.
Yog tias koj tab tom kuaj pw tsaug zog apnea, koj tus kws kho mob pw tsaug zog yuav siv pulse oximetry los ntsuas seb koj nres ua pa li cas thaum kawm pw tsaug zog.Covmem tes oximetermuaj lub teeb liab sensor uas tawm lub teeb hla ntawm daim tawv nqaij los ntsuas koj lub plawv dhia (lossis lub plawv dhia) thiab cov pa oxygen hauv koj cov ntshav.Qib ntawm cov pa oxygen hauv cov ntshav yog ntsuas los ntawm cov xim.Cov ntshav oxidized heev yog redder, thaum cov ntshav uas tsis muaj oxygen cov ntsiab lus yog bluer.Qhov no yuav hloov qhov zaus ntawm lub wavelength ntawm lub teeb rov qab mus rau lub sensor.Cov ntaub ntawv no tau sau tseg thoob plaws ib hmos ntawm kev sim pw tsaug zog thiab sau rau hauv daim ntawv.Koj tus kws kho mob pw tsaug zog yuav tshawb xyuas daim ntawv kawg ntawm koj qhov kev ntsuam xyuas pw tsaug zog los txiav txim seb koj cov pa oxygen tau poob qis npaum li cas thaum koj kuaj pw tsaug zog.
Ib qho oxygen saturation ntau dua 95% yog suav tias yog qhov qub.Cov ntshav cov pa oxygen tsawg dua 92% tuaj yeem qhia tau tias koj muaj teeb meem ua pa thaum pw tsaug zog, uas txhais tau hais tias koj pw tsaug zog apnea lossis lwm yam kab mob, xws li snoring hnyav, COPD lossis mob hawb pob.Txawm li cas los xij, nws yog ib qho tseem ceeb rau koj tus kws kho mob kom nkag siab lub sij hawm nws yuav siv sij hawm rau koj cov pa oxygen kom poob qis dua 92%.Cov pa oxygen yuav tsis poob rau ntev txaus lossis tsis txaus ua rau koj lub cev tsis zoo lossis tsis zoo.
Yog tias koj xav paub txog cov ntsiab lus ntawm cov pa oxygen hauv koj cov ntshav thaum pw tsaug zog, koj tuaj yeem mus rau lub chaw pw tsaug zog rau kev kawm pw tsaug zog thaum hmo ntuj, lossis koj tuaj yeem siv lubmem tes oximetersaib xyuas koj pw hauv tsev.
Pulse oximeter tuaj yeem yog ib qho khoom siv kho mob zoo heev rau cov neeg mob pw tsaug zog apnea.Nws yog pheej yig dua li kev tshawb fawb txog kev pw tsaug zog thiab tuaj yeem nthuav qhia cov ntaub ntawv tseem ceeb ntawm koj txoj kev pw tsaug zog zoo lossis kev kho mob pw tsaug zog apnea.
