Ko te kaupapa mahi o te oximeter nail: na roto i te taraiwa i te LED whero (660nm) me te LED infrared (910nm), ko te raina puru e tohu ana i te pihi whakauru o te ngongo whiwhi ki te hemoglobin iti ka kore te hemoglobin e kawe ngota ngota hāora.
Ka kitea he kaha te kaha o te whakauru o te hemoglobin whakaheke ki te 660nm rama whero, i te mea he ngoikore te roa o te whakauru o te rama infrared 910nm.Ko te raina whero e tohu ana i te pihi whakauru o te oxyhemoglobin ina he hemoglobin me nga toto toto whero me nga ngota ngota hāora te ngongo whiwhi.Ko te whakauru o te rama whero i te 660 nm he ngoikore, me te kaha o te whakauru o te rama infrared i te 910 nm.I roto i te inenga hāora toto, ko te rerekētanga i waenga i te hemoglobin whakaheke me te hemoglobin hāora mā te kite i te rerekētanga i waenga i ngā momo whakaurunga marama e rua i ngā roangaru rerekē, ko te tino raraunga taketake mo te ine i te toto hāora hāora.I roto i te whakamatautau toto hāora, ko te 660nm me te 910nm nga roangaru e rua.Ko te mea pono, ki te whakatutuki i te tika teitei ake, i tua atu i nga roangaru e rua, tae noa ki te 8 nga roangaru, ko te take nui ko te hemoglobin tangata kaore i te whakaheke noa ki te hemoglobin.I tua atu i te oxyhemoglobin, tera ano etahi atu hemoglobin, he maha nga wa ka kite tatou i te carboxyhemoglobin,
