SpO2 yana nufin jikewar iskar oxygen jikewa, kimanta adadin iskar oxygen a cikin jini.Musamman ma, shine kashi na haemoglobin oxygenated (haemoglobin mai ɗauke da oxygen) idan aka kwatanta da jimlar adadin haemoglobin a cikin jini (oxygenated haemoglobin da ba oxygenated).
SpO2 kimantawa ne na jikewar iskar oxygen jijiya, ko SaO2, wanda ke nufin adadin haemoglobin oxygenated a cikin jini.
Haemoglobin furotin ne wanda ke ɗaukar iskar oxygen a cikin jini.Ana samunsa a cikin jajayen ƙwayoyin jini kuma yana ba su launin ja.
Ana iya auna SpO2 ta hanyar oximetry pulse, hanya kai tsaye, ba ta da ƙarfi (ma'ana ba ta haɗa da shigar da kayan aiki a cikin jiki ba).Yana aiki ta hanyar fiddawa sannan kuma yana ɗaukar haske mai ratsawa ta hanyoyin jini (ko capillaries) a cikin yatsa.Bambance-bambancen kalaman haske da ke wucewa ta cikin yatsa zai ba da ƙimar ma'aunin SpO2 saboda ƙimar saturation na iskar oxygen yana haifar da bambancin launin jini.
Wannan kimar tana wakilta da kashi.Idan Withings Pulse Ox™ ya ce kashi 98%, wannan yana nufin kowane jan jini ya ƙunshi 98% oxygenated da 2% na haemoglobin mara iskar oxygen.Ƙimar SpO2 ta al'ada ta bambanta tsakanin 95 zuwa 100%.
Kyakkyawan oxygenation na jini ya zama dole don samar da makamashin da tsokoki ke buƙata don yin aiki, wanda ke ƙaruwa yayin ayyukan wasanni.Idan ƙimar SpO2 ɗinku tana ƙasa da 95%, wannan na iya zama alamar rashin isashshen iskar oxygen na jini, wanda kuma ake kira hypoxia.
