ʻO SpO2 ke kū nei no ka peripheral capillary oxygen saturation, kahi kuhi o ka nui o ka oxygen i loko o ke koko.ʻOi aku ka kikoʻī, ʻo ia ka pākēneka o ka hemoglobin i loaʻa i ka oxygen (haemoglobin i loko o ka oxygen) i hoʻohālikelike ʻia i ka huina o ka hemoglobin i loko o ke koko (oxygenated a me non-oxygenated haemoglobin).
ʻO SpO2 kahi koho o ka oxygen saturation arterial, a i ʻole SaO2, e pili ana i ka nui o ka hemoglobin oxygen i loko o ke koko.
ʻO ka Hemoglobin kahi pūmua e lawe i ka oxygen i loko o ke koko.Loaʻa ia i loko o ke koko ʻulaʻula a hāʻawi iā lākou i ko lākou ʻulaʻula.
Hiki ke ana ʻia ka SpO2 e ka pulse oximetry, kahi ala ʻole, ʻaʻole invasive (ʻo ia hoʻi, ʻaʻole ia e komo i ka hoʻokomo ʻana i nā mea kani i loko o ke kino).Hoʻohana ia ma ka hoʻokuʻu ʻana a hoʻopaʻa ʻia i kahi nalu māmā e hele ana ma nā kīʻaha koko (a i ʻole capillaries) ma ka manamana lima.ʻO ka hoʻololi ʻana o ka nalu māmā e hele ana ma ka manamana lima e hāʻawi i ka waiwai o ke ana SpO2 no ka mea ʻo ke degere o ka saturation oxygen e hoʻololi i ke kala o ke koko.
Hōʻike ʻia kēia waiwai e ka pākēneka.Inā ʻōlelo kāu Withings Pulse Ox™ he 98%, ʻo ia hoʻi, ua hana ʻia kēlā me kēia ʻāpana koko ʻulaʻula me 98% oxygenated a me 2% non-oxygenated hemoglobin.ʻOkoʻa nā waiwai SpO2 maʻamau ma waena o 95 a me 100%.
Pono ka oxygenation koko maikaʻi no ka hāʻawi ʻana i ka ikehu e pono ai kou mau ʻiʻo i mea e hana ai, e piʻi aʻe i ka wā o kahi haʻuki.Inā ʻoi aku ka nui o kāu SpO2 ma lalo o 95%, he hōʻailona paha ia o ka maikaʻi ʻole o ka oxygenation koko, i kapa ʻia ʻo hypoxia.
