ʻO ka saturation oxygen koko kekahi o nā hōʻailona koʻikoʻi o ke olakino kino.Pono e mālama ʻia ka saturation oxygen koko o nā kānaka olakino maʻamau ma waena o 95% a me 100%.Inā he haʻahaʻa ma lalo o 90%, ua komo i ka pae o ka hypoxia.He hypoxia ko'iko'i ka %, he mea ia e poino nui ai ke kino a e pilikia ai ke ola.
ʻO ka saturation oxygen koko he mea nui physiological parameter e hōʻike ana i ka hana hanu a me ke kahe.Wahi a nā helu helu ʻole, ʻo ka hapa nui o nā kumu no nā kūkākūkā pilikia me nā keʻena hanu i nā keʻena kūpono i nā halemai e pili ana i ka oxygen koko.Ua ʻike mākou a pau ʻaʻole hiki ke hoʻokaʻawale ʻia ka saturation oxygen haʻahaʻa mai nā maʻi hanu, akā ʻaʻole nā mea a pau e emi ai ka saturation oxygen koko ma muli o nā maʻi hanu.
He aha nā kumu o ke koko haʻahaʻa o ka oxygen saturation?
1. Inā haʻahaʻa loa ke kaomi ʻāpana o ka oxygen inhaled.Ke lawa ʻole ka ʻike o ka oxygen inhaled, hiki ke emi ka saturation oxygen.Hoʻohui pū ʻia me ka mōʻaukala olakino, pono e nīnau ʻia ka mea maʻi inā ua hele ʻo ia i kahi pāpū ma luna o 3000m, lele kiʻekiʻe, piʻi ma hope o ka luʻu ʻana, a me nā mines maikaʻi ʻole.
2. Ina paha he keakea ka ea.Pono e noʻonoʻo inā he obstructive hypoventilation i hoʻokumu ʻia e nā maʻi e like me ka hānō, COPD, kulu aʻa alelo, a me ke keakea ʻana o ke kino ʻē i nā mea huna hanu.
3. Ina paha he pilikia ka ea.Pono e noʻonoʻo inā loaʻa i ka mea maʻi ka maʻi maʻi maʻi, ka maʻi tuberculosis, ka diffuse pulmonary interstitial fibrosis, pulmonary edema, pulmonary embolism a me nā maʻi ʻē aʻe e pili ana i ka hana ventilation.
4. He aha ka maikaʻi a me ka nui o ka Hb e lawe i ka oxygen i loko o ke koko.ʻO ka hiʻohiʻona o nā mea ʻino, e like me ka make CO, ka nitrite poisoning, a me ka piʻi nui ʻana o ka hemoglobin abnormal, ʻaʻole pili wale i ka lawe ʻana o ka oxygen i loko o ke koko, akā pili pū kekahi i ka hoʻokuʻu ʻana o ka oxygen.
5. Inā loaʻa i ka mea maʻi ke kaomi colloid osmotic kūpono a me ka nui o ke koko.ʻO ke kaomi osmotic colloid kūpono a me ka nui o ke koko kekahi o nā kumu nui e mālama ai i ka saturation oxygen maʻamau.
6. He aha ka puka o ka naʻau o ka mea maʻi?ʻO ka mālama ʻana i ka hāʻawi ʻana i ka oxygen maʻamau i nā kino pono ke kākoʻo ʻia e ka lawa ʻana o ka naʻau.
7. Tissue a me ke kino microcirculation.ʻO ka hiki ke mālama i ka oxygen kūpono e pili pū ana me ka metabolism o ke kino.Ke nui loa ka metabolism o ke kino, e hoʻemi nui ʻia ka ʻike o ka oxygen koko venous, a e alakaʻi ke koko venous i ka hypoxia ʻoi aku ka koʻikoʻi ma hope o ka hele ʻana i ke kahe pulmonary shunted.
8. Ka hoʻohana ʻana i ka oxygen ma nā ʻiʻo a puni.Hiki ke hoʻohana wale i ka oxygen manuahi, a hiki ke hoʻohana ʻia ka oxygen i hui pū ʻia me Hb e nā ʻiʻo ke hoʻokuʻu ʻia.Hoʻololi nā hoʻololi i ka pH, 2,3-DPG, a pēlā aku i ka dissociation o ka oxygen mai Hb.
9. Ka ikaika o ka pulupulu.Ana ʻia ka saturation oxygen ma muli o ka hoʻololi ʻana o ka absorbance i hana ʻia e ka arterial pulsation, no laila pono ke kau ʻia ka transducer ma kahi pūnaewele me ke koko puʻupuʻu.ʻO nā mea e hoʻonāwaliwali ai i ke kahe o ke koko, e like me ka hoʻoulu ʻana i ke anuanu, ka hauʻoli o ke aʻalolo sympathetic, ka maʻi diabetes a me ka arteriosclerosis, e hōʻemi i ka hana ana o ka mea kani.ʻAʻole hiki ke ʻike ʻia ka SpO2 i nā poʻe maʻi me ka cardiopulmonary bypass a me ka hopu puʻuwai.
