SpO2 imayimira peripheral capillary oxygen saturation, kuyerekezera kwa kuchuluka kwa okosijeni m'magazi.Makamaka, ndi kuchuluka kwa hemoglobin wokhala ndi okosijeni (hemoglobini yokhala ndi okosijeni) poyerekeza ndi kuchuluka kwa hemoglobini m'mwazi (oxygenated and non oxygenated haemoglobin).
SpO2 ndi chiŵerengero cha mpweya wabwino wa okosijeni, kapena SaO2, womwe umatanthawuza kuchuluka kwa hemoglobini ya okosijeni m'magazi.
Hemoglobin ndi puloteni yomwe imanyamula mpweya m'magazi.Amapezeka mkati mwa maselo ofiira a magazi ndipo amawapatsa mtundu wawo wofiira.
SpO2 ikhoza kuyesedwa ndi pulse oximetry, njira yosalunjika, yosasokoneza (kutanthauza kuti sichiphatikizapo kulowetsa zida m'thupi).Zimagwira ntchito potulutsa ndiyeno kutulutsa kuwala kodutsa m'mitsempha yamagazi (kapena ma capillaries) chala.Kusintha kwa kuwala komwe kumadutsa chala kudzapereka mtengo wa muyeso wa SpO2 chifukwa kuchuluka kwa machulukidwe a okosijeni kumayambitsa kusiyanasiyana kwamitundu yamagazi.
Mtengo uwu ukuimiridwa ndi peresenti.Ngati Withings Pulse Ox™ yanu ikuti 98%, izi zikutanthauza kuti selo lililonse lofiira lamagazi limapangidwa ndi 98% yokhala ndi okosijeni ndi 2% ya haemoglobin yopanda okosijeni.Makhalidwe abwinobwino a SpO2 amasiyana pakati pa 95 ndi 100%.
Mpweya wabwino wa oxygen m'magazi ndi wofunikira kuti upereke mphamvu zomwe minofu yanu imafunikira kuti igwire ntchito, zomwe zimawonjezeka panthawi yamasewera.Ngati mtengo wanu wa SpO2 uli pansi pa 95%, chimenecho chingakhale chizindikiro cha kuchepa kwa oxygen m'magazi, kumatchedwanso hypoxia.
