I-oximeter yewotshi ye-Narigmed ikulungele ngakumbi ukunxiba kunye nokulinganisa.Ngokukodwa, iteknoloji ye-oksijeni yegazi kwimveliso ingasetyenziselwa iimeko ezahlukeneyo kunye nabantu bazo zonke iithoni zesikhumba, kwaye isetyenziswe ngoogqirha ukulinganisa i-oxygen yegazi, izinga lokubetha, izinga lokuphefumula kunye ne-perfusion index.Ilungiselelwe ngokuthe ngqo kwaye iphuculwe kwi-anti-motion kunye nokusebenza kwe-perfusion ephantsi.Ngokomzekelo, phantsi kokunyakaza okungahleliwe okanye okuqhelekileyo kwe-0-4Hz, i-0-3cm, ukuchaneka kwe-pulse oximetry (SpO2) yi-± 3%, kunye nokuchaneka komlinganiselo wesantya se-pulse ± 4bpm.Xa isalathisi se-hypoperfusion sikhulu okanye silingana ne-0.025%, ukuchaneka kwe-pulse oximetry (SpO2) yi-± 2%, kwaye ukuchaneka komlinganiselo we-pulse ± 2bpm.
