ʻOi aku ka maʻalahi o ka wati oximeter o Narigmed e ʻaʻahu a ana.Ma keʻano kūikawā, hiki ke hoʻohanaʻia kaʻenehana oxygen koko i loko o ka huahana no nāʻano likeʻole a me nā kānaka o nāʻili a pau, a hoʻohanaʻia e nā kauka e ana i ka oxygen koko, ka pulse rate, ka hanu hanu a me ka helu perfusion.Hoʻopili pono ʻia a hoʻomaikaʻi ʻia no ka hana anti-motion a me ka haʻahaʻa perfusion.No ka laʻana, ma lalo o ka neʻe ʻana a i ʻole ka neʻe maʻamau o 0-4Hz, 0-3cm, ʻo ka pololei o ka pulse oximetry (SpO2) ʻo ± 3%, a ʻo ka pololei o ke ana ʻana o ka pulse rate he ± 4bpm.Ke ʻoi aku ka nui o ka helu hypoperfusion ma mua a i ʻole like me 0.025%, ʻo ka pololei o ka pulse oximetry (SpO2) ʻo ± 2%, a ʻo ka pololei o ke ana ʻana o ka pulse he ± 2bpm.
