Pulse oximetry yog tshwj xeeb tshaj yog yooj yim rau noninvasive nruam ntsuas ntawm cov ntshav oxygen saturation.Hauv qhov sib piv, cov ntshav ntshav yuav tsum tau txiav txim siab hauv chav kuaj ntawm cov ntshav kos.Pulse oximetry yog qhov muaj txiaj ntsig zoo rau txhua qhov chaw uas tus neeg mob cov pa oxygenation tsis ruaj khov, suav nrog kev saib xyuas hnyav, kev ua haujlwm, kev rov qab los, kev kub ntxhov thiab tsev kho mob hauv tsev kho mob, cov kws tsav dav hlau hauv lub dav hlau tsis muaj zog, rau kev ntsuam xyuas ntawm ib tus neeg mob cov pa oxygenation, thiab txiav txim siab qhov ua tau zoo ntawm lossis xav tau cov pa oxygen ntxiv. .Txawm hais tias lub pulse oximeter yog siv los saib xyuas cov pa oxygenation, nws tsis tuaj yeem txiav txim siab cov metabolism ntawm oxygen, lossis cov pa oxygen siv los ntawm tus neeg mob.Rau lub hom phiaj no, nws yog ib qho tsim nyog los ntsuas cov pa roj carbon dioxide (CO2) qib.Nws muaj peev xwm kuj siv tau los xyuas qhov txawv txav hauv qhov cua.Txawm li cas los xij, kev siv lub tshuab pulse oximeter txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua pa yog cuam tshuam nrog kev siv cov pa oxygen ntxiv.Yog li, niaj hnub kev tswj hwm ntawm cov pa oxygen ntxiv tuaj yeem ua tsis tau yog tias tus neeg mob muaj peev xwm tswj tau cov pa oxygen txaus hauv chav cua, vim nws tuaj yeem ua rau hypoventilation mus tsis pom.
Vim tias lawv txoj kev yooj yim ntawm kev siv thiab muaj peev xwm muab qhov tseem ceeb ntawm cov pa oxygen saturation tas li thiab tam sim ntawd, pulse oximeters yog qhov tseem ceeb hauv cov tshuaj thaum muaj xwm txheej ceev thiab tseem muaj txiaj ntsig zoo rau cov neeg mob uas muaj teeb meem ua pa lossis mob plawv, tshwj xeeb tshaj yog COPD, lossis rau kev kuaj mob ntawm qee qhov kev pw tsaug zog. xws li apnea thiab hypopnea.Rau cov neeg mob uas muaj obstructive pw tsaug zog apnea, pulse oximetry nyeem yuav nyob rau hauv 70% 90% ntau ntawm cov sij hawm siv sim pw.
Portable roj teeb ua haujlwm pulse oximeters muaj txiaj ntsig zoo rau cov kws tsav dav hlau ua haujlwm hauv cov dav hlau tsis muaj zog siab tshaj 10,000 ko taw (3,000 m) lossis 12 ,500 ko taw (3 ,800 m) hauv Teb Chaws Asmeskas qhov twg yuav tsum muaj oxygen ntxiv.Portable pulse oximeters kuj tseem siv tau rau cov neeg nce toj thiab cov neeg ncaws pob uas nws cov pa oxygen tuaj yeem txo qis ntawm qhov siab lossis nrog kev tawm dag zog.Qee lub tshuab pulse oximeters siv cov khoom siv uas ntsuas tus neeg mob cov ntshav oxygen thiab mem tes, ua kev ceeb toom kom kuaj ntshav cov pa oxygen.
Kev sib txuas ua ntej tau ua rau cov neeg mob muaj lawv cov ntshav oxygen saturation tsis tu ncua saib xyuas yam tsis muaj kev sib txuas nrog lub tsev kho mob saib xyuas, yam tsis muaj kev cuam tshuam cov ntaub ntawv ntawm tus neeg mob rov qab mus rau cov saib hauv txaj thiab lub hauv paus ntawm cov neeg mob nyob hauv nruab nrab.
Rau cov neeg mob nrog KEVID-19, pulse oximetry pab nrog kev tshawb pom ntxov ntawm qhov ntsiag to hypoxia, uas cov neeg mob tseem saib thiab xis nyob, tab sis lawv cov SpO2 yog qhov txaus ntshai heev.Qhov no tshwm sim rau cov neeg mob hauv tsev kho mob lossis hauv tsev.Tsawg SpO2 tej zaum yuav qhia tau tias muaj mob hnyav rau COVID-19, uas yuav tsum tau muaj lub tshuab ua pa.
