Puas yog pulse oximeters txhim khu kev qha ntau dua li SpO2 smartwatches thiab qoj bands? Nov yog qhov kws txawj xav.
Kev saib xyuas koj cov ntshav cov pa oxygen yog ib qho tseem ceeb tshaj plaws uas yuav tsum tau ua thaum lub sij hawm Covid kis kab mob, thiab tuaj yeem pab txiav txim seb koj puas xav tau kev kho mob. Thaum lub pulse oximeter yog lub cuab yeej mus rau kev tshuaj xyuas koj cov ntshav oxygen qib hauv tsev, koj tuaj yeem pom ntau lub smartwatches niaj hnub no uas muaj cov khoom siv hauv SpO2 sensor, kuj tau thov kom muaj peev xwm zoo ib yam, nrog rau ntxiv perks ntawm smartwatches.
Txawm li cas los xij, puas yog qhov ntawd txhais tau hais tias tus hnav khaub ncaws tshiab uas koj tau pom zoo li oximeter? Dr Zakia Khan, Senior Consultant-Interventional Cardiology ntawm Fortis Hospital, Kalyan, qhia lwm yam.
Khan piav qhia tias cov pa pulse oximeters yog qhov tseeb dua li SpO2 smartwatches. Thaum lub smartwatch lossis lub cev qoj ib ce tuaj yeem ua haujlwm ib yam li pulse oximeter, cov neeg siv feem ntau tuaj yeem xav tias yuav muaj qhov sib txawv ntawm kev nyeem ntawv vim qhov txawv ntawm qhov raug.
Qhov sib txawv no tuaj yeem tshwm sim los ntawm qhov ua li cas ob lub cuab yeej ntsuas koj cov qib oxygen. Raws li Khan piav qhia, "smartwatches siv qhov cuam tshuam oximetry thiab oximeters siv cov kev xa tawm oximetry."
Transmittance thiab reflectance oximetry yog dab tsi?
Transmittance thiab reflectance oximetry yog ob feem ntau siv cov txheej txheem uas tsis cuam tshuam los ntsuas ntshav oxygen. Lawv ob leeg siv ob lub teeb ci (infrared thiab teeb liab) thiab photodetector. Qhov sib txawv ntawm kev ua haujlwm yog nyob ntawm qhov chaw ntawm cov khoom.
Hauv kev xa tawm oximetry, lub teeb pom kev zoo thiab photodetector yog qhov sib txawv rau ib leeg, thaum lub xaib raug kuaj (nyob rau hauv cov ntaub ntawv ntawm pulse oximeter, koj tus ntiv tes ntsuas) nyob hauv nruab nrab. Thaum lub teeb dhau los ntawm lub hom phiaj ntawm qhov chaw, lub photodetector ntawm lwm qhov kawg ntsuas lub teeb uas tau dhau los ntawm koj tus ntiv tes kom tau txais kev nyeem ntawv qib siab oxygen hauv cov ntshav.
Txawm li cas los xij, vim lawv ua haujlwm, kev xa tawm oximetry yog qhov ua tau zoo tshaj plaws hauv qhov chaw ntsuas thinner, zoo li koj tus ntiv tes.
Nyob rau hauv reflectance oximetry, lub teeb qhov chaw thiab lub photodetector yog positioned nyob rau tib sab, thiab lub diode captures lub teeb reflected tawm ntawm lub hom phiaj ntsuas qhov chaw (nyob rau hauv cov ntaub ntawv ntawm ib tug smartwatch, koj lub dab teg). Lub teeb uas cuam tshuam los ntawm cov pob txha hauv qab yog tom qab ntawd kuaj pom los ntawm diode, uas yuav siv sij hawm nyeem ntawv. Yog vim li cas reflectance oximetry feem ntau yog siv hauv smartwatches thiab qoj trackers yog vim nws tsis xav tau ib qho chaw nyias rau kev ntsuas.
Vim li cas koj thiaj li yuav tsum xaiv lub pulse oximeter rau kev nyeem kom raug
Fingertip pulse oximeters kuj tau nruab los them nyiaj rau lwm yam xws li ambient lub teeb, qhov loj ntawm tus ntiv tes thiab lub teeb absorbed los ntawm cov ntaub so ntswg hauv koj tus ntiv tes. Khan kuj taw qhia tias "pulse oximeters yog qhov tseeb dua vim tias lawv muaj dual sensors," ib yam dab tsi txhua lub smartwatches yuav tsis tuaj nrog.
"Pulse oximeters kuj tseem pheej yig dua," Khan taw qhia, ua rau lawv siv tau ntau dua rau cov neeg uas tsis tuaj yeem them taus lub smartwatch. Txawm hais tias ntau lub pulse oximeters raug nqi qis dua Rs 2,000, SpO2-pab smartwatch tuaj yeem raug nqi nyob qhov twg ntawm Rs 3,000 txog Rs 50,000, thiab tseem tuaj yeem tsis tuaj yeem muab rau koj tib qhov kev ntseeg siab hauv kev nyeem ntawv.
Cov neeg yuav khoom kuj tuaj yeem nqis peev hauv pulse oximeters uas tseem muab kev nyeem ntawv hauv lub waveform, uas Khan hais tias feem ntau zoo dua rau oximeters uas tsuas yog muab cov ntaub ntawv lej xwb.
Yuav ua li cas txog thaum koj nrhiav tsis tau ib qho oximeter?
Yog tias koj pom koj tus kheej tsis tuaj yeem yuav lub oximeter vim kev lag luam tsis txaus, raws li tau pom thaum lub sijhawm Covid thib ob hauv ntau thaj tsam xyoo tas los, koj tuaj yeem siv SpO2 smartwatch, hais Khan.
Txawm li cas los xij, nco ntsoov tias smartwatches zoo dua rau kev siv lub cev thiab tsis siv kho mob. Tsis tas li ntawd, txhua lub smartwatches uas muaj SpO2 sensors yuav tsis muab rau koj nyeem tib yam. Khan taw qhia tias cov sensors siv los ntawm Apple hauv nws cov khoom siv tau zoo dua li lwm cov smartwatches. Tab sis tom qab ntawd nws tsis yog qhov kev xaiv pheej yig tshaj plaws hauv khw Indian.
Khan hais ntxiv tias muaj lub ntsuas pulse oximeter hauv tsev, nrog rau lub ntsuas ntshav siab digital thiab ntsuas ntshav qab zib yog qhov yuav tsum tau ua thaum lub sijhawm no. Cov cuab yeej no tuaj yeem yog qhov tseem ceeb thaum koj xav tau saib xyuas koj cov khoom tseem ceeb sai. Lawv kuj yog ib qho yooj yim-rau-siv thiab Khan hais tias kev tshawb nrhiav ceev hauv YouTube tuaj yeem pab cov neeg siv tawm nrog ntau hom pulse oximeters thiab lwm yam kev saib xyuas kev noj qab haus huv thiab siv lawv li cas.
