ʻO ke kumu hana o ka nail oximeter: ma ka hoʻokele ʻana i kahi LED ʻulaʻula (660nm) a me kahi LED infrared (910nm), hōʻike ka laina polū i ka pihi induction o ka pahu e loaʻa ana i ka hemoglobin i hoʻemi ʻia ke lawe ʻole ka hemoglobin i nā molekele oxygen.
Hiki ke ʻike ʻia he ikaika loa ka absorption o ka hemoglobin emi i 660nm ʻulaʻula, ʻoiai ʻo ka lōʻihi o ka absorption o 910nm infrared light he palupalu.ʻO ka laina ʻulaʻula e hōʻike ana i ka hemoglobin a me nā ʻulaʻula ʻulaʻula me nā molekole oxygen i ka wā e paʻa ai ka paipu e loaʻa ana i ka oxyhemoglobin, ʻoi aku ka nāwaliwali o ke kukui ʻulaʻula 660nm, a ʻoi aku ka ikaika o ka absorption o 910nm infrared light.Ma ke ana o ka oxygen koko, ʻo ka ʻokoʻa ma waena o ka hemoglobin liʻiliʻi a me ka hemoglobin oxygenated ma o ka ʻike ʻana i ka ʻokoʻa ma waena o nā ʻano ʻelua o ka lawe māmā ʻana i nā lōʻihi hawewe like ʻole ka ʻikepili kumu loa no ke ana ʻana i ka saturation oxygen koko.I ka ho'āʻo oxygen koko, ʻo 660nm a me 910nm nā nalu maʻamau ʻelua.ʻO kaʻoiaʻiʻo, no ka loaʻaʻana o ka pololei kiʻekiʻe, me ka hoʻohuiʻana iʻelua mau nalu, a hiki i ka 8 mau nalu,ʻo ke kumu nuiʻaʻole i emi wale ka hemoglobin kanaka i ka hemoglobin.Ma waho aʻe o ka oxyhemoglobin, aia kekahi mau hemoglobins, ʻike pinepine mākou i ka carboxyhemoglobin,
