Lub pulse oximeter ntau npaum li cas

Lub pulse oximeter feem ntau yog nruab nrab ntawm 60 thiab 100.

Lub ntsiab ntsuas ntsuas ntawm pulse oximeter yog pulse rate thiab ntshav oxygen saturation. Cov mem tes tuaj yeem sawv cev los ntawm P2, thiab tus nqi ib txwm muaj feem ntau yog nyob nruab nrab ntawm 60 thiab 100. Tau kawg, thaum tib neeg ntshai lossis tawm dag zog, lub plawv dhia yuav nce ntxiv. Lwm qhov taw qhia yog ntshav oxygen saturation, uas yog cim los ntawm SpO2. Cov ntshav oxygen saturation tsuas yog lub peev xwm ntawm cov pa oxygen thiab hemoglobin ua ke los ntawm cov pa oxygen hauv cov ntshav, suav txog feem pua ​​​​ntawm tag nrho cov hemoglobin uas tuaj yeem ua ke, uas yog, qhov concentration ntawm cov ntshav oxygen hauv cov ntshav, thiab nws yog qhov tseem ceeb ntawm lub cev tsis muaj zog. ua pa ncig. Nws yog qhov yooj yim heev los kuaj xyuas los ntawm tus ntiv tes clip txoj kev tsis muaj kev raug mob. Tus nqi ib txwm yog 95 feem pua ​​​​rau 98 feem pua. Tau kawg, qee qhov tuaj yeem ncav cuag 100 feem pua. Yog tias nws qis dua 95 feem pua, nws qhia tau tias muaj hypoxia. Rau cov kab mob ua pa ntev, xws li COPD, mob hawb pob, kab mob pulmonary interstitial, thiab kab mob plawv, hypoxia feem ntau tshwm sim. Lub oximeter tuaj yeem coj cov kev kho mob thiab ua tib zoo saib xyuas cov ntshav oxygen. Nws yog ib qho cuab yeej yooj yim heev.

Lub pulse oximeter muab ib txoj hauv kev uas tsis muaj kev cuam tshuam los ntsuas cov ntshav oxygen saturation lossis arterial heme saturation. Lub pulse oximeter tseem tuaj yeem ntes cov hlab ntsha ntawm lub plawv, yog li nws tuaj yeem suav thiab qhia tus neeg mob lub plawv dhia. Lub pulse oximeter yog cov cuab yeej kho mob uas ntsuas cov pa oxygen hauv cov neeg mob cov ntshav.

Ntxiv nrog rau lub plawv dhia, ntshav siab, lub ntsws ua pa thiab qhov kub thiab txias, pulse oxygen yog suav tias yog qhov thib tsib tseem ceeb tshaj plaws ntawm kev noj qab haus huv. Hemoglobin yog ib feem tseem ceeb ntawm cov qe ntshav thiab yog lub luag haujlwm thauj cov pa oxygen ntawm lub ntsws mus rau lwm cov ntaub so ntswg ntawm lub cev. Tus nqi ntawm cov pa oxygen muaj nyob rau hauv hemoglobin txhua lub sijhawm yog hu ua ntshav oxygen saturation, uas yog qhia raws li feem pua, uas yog, qhov piv ntawm cov pa oxygen ntawm hemoglobin mus rau oxygen nqa peev xwm ntawm hemoglobin. Ntshav oxygen saturation yog ib qho tseem ceeb physiological parameter xav txog seb tib neeg ua pa thiab oxygen cov ntsiab lus yog ib txwm, uas yog ib qho tseem ceeb physiological parameter, qhia seb tib neeg cov ntaub so ntswg noj qab nyob zoo.
