SpO2 sawv cev rau peripheral capillary oxygen saturation, kev kwv yees ntawm cov pa oxygen hauv cov ntshav.Tshwj xeeb tshaj yog, nws yog qhov feem pua ntawm cov pa oxygenated hemoglobin (haemoglobin uas muaj oxygen) piv rau tag nrho cov hemoglobin hauv cov ntshav (oxygenated thiab non-oxygenated hemoglobin).
SpO2 yog ib qho kev kwv yees ntawm arterial oxygen saturation, los yog SaO2, uas yog hais txog cov pa oxygenated hemoglobin hauv cov ntshav.
Hemoglobin yog cov protein uas nqa oxygen hauv cov ntshav.Nws muaj nyob rau hauv cov qe ntshav liab thiab muab lawv cov xim liab.
SpO2 tuaj yeem ntsuas tau los ntawm pulse oximetry, ib qho kev tsis ncaj, tsis muaj kev cuam tshuam (lub ntsiab lus nws tsis koom nrog kev qhia txog cov cuab yeej rau hauv lub cev).Nws ua hauj lwm los ntawm emitting thiab ces nqus ib lub teeb yoj dhau los ntawm cov hlab ntsha (los yog capillaries) nyob rau hauv lub ntsis ntiv tes.Ib qho kev hloov pauv ntawm lub teeb nthwv dej dhau los ntawm tus ntiv tes yuav muab qhov txiaj ntsig ntawm SpO2 ntsuas vim tias qib ntawm oxygen saturation ua rau muaj kev hloov pauv hauv cov ntshav xim.
Tus nqi no sawv cev los ntawm ib feem pua.Yog tias koj Withings Pulse Ox ™ hais tias 98%, qhov no txhais tau tias txhua lub qe ntshav liab yog tsim los ntawm 98% oxygenated thiab 2% non-oxygenated hemoglobin.Ib txwm SpO2 tus nqi sib txawv ntawm 95 thiab 100%.
Cov ntshav oxygenation zoo yog qhov tsim nyog los muab lub zog koj cov leeg xav tau txhawm rau ua haujlwm, uas nce ntxiv thaum lub sijhawm ua kis las.Yog tias koj tus nqi SpO2 qis dua 95%, qhov ntawd tuaj yeem yog lub cim ntawm cov ntshav oxygenation tsis zoo, tseem hu ua hypoxia.
