Hiki i ka PULSE oximetry ke helu i ka hemoglobin oxygen saturation mai ka ratio o ka pulsatile a i ka huina kukui ʻulaʻula i hoʻoili ʻia e ka ratio like no ke kukui infrared transilluminating i kahi manamana lima, pepeiao, a i ʻole nā mea ʻē aʻe.Pono e kūʻokoʻa ka saturation i loaʻa mai ka pigmentation o ka ʻili, a me nā ʻano ʻē aʻe he nui, e like me ka hemoglobin concentration, nail polish, lepo, a me ka jaundice.ʻO kekahi mau haʻawina hoʻomalu nui e hoʻohālikelike ana i nā maʻiʻeleʻele a me ke keʻokeʻo (380 mau kumuhana) 1,2 i hōʻikeʻole i nā hewa pili i ka puaʻa i nā oximeters pulse i ka saturation maʻamau.
Eia naʻe, ua loiloi ʻo Severinghaus a me Kelleher3 i nā ʻikepili mai kekahi mau mea noiʻi i hōʻike i nā hewa anecdotal (+3 a + 5%) i nā maʻi ʻeleʻele.et al.8 Coteet al.Ua hōʻike ʻo 9 e hiki ke hana hewa ka poli kui a me ka ʻīnika ma ka ʻili, kahi ʻike i hōʻoia ʻia e nā poʻe ʻē aʻe mai ka inika manamana lima, 10 henna,11 a me ka meconium.et al.Ua ʻike ʻo 14 i ka overestimation o ka saturation, ʻoi loa i ka saturation haʻahaʻa i nā maʻi pigmented (Indian, Malayvs.Pākē).Ua hōʻike ka ʻenehana Subcommittee o ka Hui Hana ma ka mālama koʻikoʻi, ke Kuhina Ola ʻo Ontario, 15 i nā hewa i ʻae ʻole ʻia i ka pulse oximetry ma ka saturation haʻahaʻa i nā kumuhana pigmented.Ua hoʻohālikelike ʻo Zeballos lāua ʻo Weisman16 i ka pololei o ka Hewlett-Packard (Sunnyvale, CA) ear oximeter a me ka Biox II pulse oximeter (Ohmeda, Andover, MA) i loko o 33 mau ʻōpio ʻeleʻele e hoʻoikaika ana i ʻekolu mau kiʻekiʻe like ʻole.Ma kahi kiʻekiʻe o 4,000 m, kahi o ka oxygen saturation arterial (Sao2) mai 75 a 84%, ua hoʻohaʻahaʻa ka Hewlett-Packard iā Sao2by 4.8 ± 1.6%, aʻo ka Biox i hoʻonui i ka Sao2by 9.8 ± 1.8% (n = 22).Ua ʻōlelo ʻia ʻo kēia mau hewa, i hōʻike mua ʻia ma nā keʻokeʻo, ua hoʻonui ʻia i nā ʻeleʻele.
I loko o kā mākou mau makahiki he nui o ka hoʻāʻo ʻana i ka pololei o ka pulse oximeter i nā saturation oxygen ma lalo o 50%, ua ʻike mākou i kekahi manawa i ke kiʻekiʻe kiʻekiʻe maikaʻi ʻole, ʻoi aku ka haʻahaʻa haʻahaʻa haʻahaʻa, i kekahi akā ʻaʻole i nā kumuhana pigmented hohonu.No laila, ua hoʻolālā pono ʻia kēia noiʻi e hoʻoholo inā pili nā hewa ma Sao2 haʻahaʻa me ka waihoʻoluʻu ʻili.
ʻO nā pulse oximeters āpau i kūʻai ʻia ma ʻAmelika Hui Pū ʻIa e koi ʻia e ka US Food and Drug Administration e hoʻāʻo ʻia a hōʻoia ʻia he pololei i ka liʻiliʻi ma lalo o ± 3% root mean square error ma Sao2values ma waena o 70 a me 100%.ʻO ka hapa nui o ka calibration a me ka hōʻoia hōʻoia i mālama ʻia i nā kumuhana manawaleʻa me ka pigmentation ʻili māmā.
Ua ʻōlelo hou mai nei ka Food and Drug Administration i nā haʻawina no ka pololei o ka pulse oximeter i waiho ʻia no ka ʻae ʻana o ka meaʻai a me nā lāʻau lapaʻau i nā kumuhana me ka nui o ka ʻili o ka ʻili, ʻoiai ʻaʻole i hāʻawi ʻia kahi koi nui.ʻAʻole mākou ʻike i ka ʻikepili e kākoʻo ana i kēia hana.
Inā loaʻa ka manaʻo koʻikoʻi a reproducible maikaʻi i ka saturation haʻahaʻa i nā kumuhana ʻili ʻeleʻele, e hoʻonui ʻia ka hoʻokomo ʻana i nā kumuhana ʻili ʻeleʻele i ka hui hoʻāʻo mean root mean square errors, lawa paha e hōʻole ʻia e ka Food and Drug Administration.Inā ʻike ʻia ka manaʻo like ʻole ma ka saturation haʻahaʻa i nā mea ʻili ʻeleʻele ma nā oximeter pulse āpau, pono e hāʻawi ʻia nā lepili ʻōlelo aʻo i nā mea hoʻohana, me nā kumu hoʻoponopono i manaʻo ʻia.
