SPO2hiki ke hoʻokaʻawale ʻia i nā ʻāpana penei: "S" ʻo ia ka saturation, "P" ʻo ia ka pulse, a ʻo "O2" ʻo ia ka oxygen.ʻO kēia acronym e ana i ka nui o ka oxygen i hoʻopili ʻia i nā sela hemoglobin i loko o ka ʻōnaehana kahe koko.I ka pōkole, pili kēia waiwai i ka nui o ka oxygen i lawe ʻia e nā ʻulaʻula ʻulaʻula.Hōʻike kēia ana i ka maikaʻi o ka hanu ʻana o ka mea maʻi a me ka maikaʻi o ke kahe koko ma ke kino.Hoʻohana ʻia ka saturation oxygen e hōʻike i ka hopena o kēia ana.ʻO ka awelika heluhelu no ke kanaka makua olakino maʻamau he 96%.
Hoʻohana ʻia ka saturation o ka oxygen koko me ka pulse oximeter, e komo pū ana me kahi mea nānā kamepiula a me nā lima lima.Hiki ke hoʻopaʻa ʻia nā moena lima ma nā manamana lima, manamana wāwae, puka ihu a i ʻole nā pepeiao pepeiao.Hōʻike ka mea nānā i kahi heluhelu e hōʻike ana i ka nui o ka oxygen i loko o ke koko o ka mea maʻi.Hana ʻia kēia me ka hoʻohana ʻana i nā nalu hiki ke wehewehe ʻia a me nā hōʻailona lohe ʻia, e pili ana i ka pulse o ka mea maʻi.E like me ka hāʻule o ka oxygen i loko o ke koko, e emi ana ka ikaika hōʻailona.Hōʻike pū ka mea nānā i ka puʻuwai puʻuwai a loaʻa iā ia kahi puʻupuʻu, ke wikiwiki / lohi ka pulse a kiʻekiʻe loa / haʻahaʻa ka saturation, hoʻopuka ʻia kahi hōʻailona alarm.
ʻO kamea hoʻonaʻauao kokoana i ke koko oxygenated a me ke koko hypoxic.Hoʻohana ʻia ʻelua alapine like ʻole e ana i kēia mau ʻano koko ʻelua: nā alapine ʻulaʻula a me ka infrared.Kapa ʻia kēia ʻano hana spectrophotometry.Hoʻohana ʻia ke alapine ʻulaʻula e ana i ka hemoglobin desaturated, a hoʻohana ʻia ke alapine infrared e ana i ke koko oxygenated.Inā hōʻike ia i ka absorption nui loa i ka hui infrared, hōʻike kēia i ka saturation kiʻekiʻe.ʻO ka mea ʻē aʻe, inā hōʻike ʻia ka absorption kiʻekiʻe i ka ʻulaʻula, hōʻike kēia i ka saturation haʻahaʻa.
Hoʻouna ʻia ke kukui ma o ka manamana lima, a nānā ʻia nā kukuna i hoʻouna ʻia e ka mea hoʻokipa.Hoʻopili ʻia kekahi o kēia kukui e nā ʻiʻo a me ke koko, a ke hoʻopiha ʻia nā aʻa i ke koko, piʻi ka absorption.Pēlā nō, i ka wā ʻole o nā aʻa, hāʻule ka pae o ka absorption.No ka mea i loko o kēia noi, ʻo ka mea hoʻololi wale nō ka pulsating flow, hiki ke unuhi ʻia ka ʻāpana static (ʻo ia hoʻi ka ʻili a me ka ʻiʻo) mai ka helu ʻana.No laila, me ka hoʻohana ʻana i nā lōʻihi hawewe ʻelua o ka mālamalama i hōʻiliʻili ʻia i ke ana, e helu ana ka pulse oximeter i ka saturation o ka hemoglobin oxygenated.
97% hoʻonaʻauao=97% ʻāpana ʻāpana oxygen (maʻamau)
90% saturation = 60% oxygen hapa puʻe (pilikia)
80% saturation = 45% ʻāpana ʻāpana o ke koko (hypoxia koʻikoʻi)
