Umgaqo osebenzayo we-nail oximeter: ngokuqhuba ngokulandelelana i-LED ebomvu (i-660nm) kunye ne-LED ye-infrared (910nm), umgca ohlaza okwesibhakabhaka ubonisa i-curve induction ye-tube yokufumana kwi-hemoglobin encitshisiweyo xa i-hemoglobin ingathwali i-oxygen molecules.
Kuya kubonakala ukuba ukufunxwa kwe-hemoglobin encitshisiweyo ukuya kwi-660nm yokukhanya okubomvu kunamandla, ngelixa ubude be-910nm bokukhanya kwe-infrared bubuthathaka.Umgca obomvu umele i-hemoglobin kunye neeseli ezibomvu zegazi ezineemolekyuli ze-oksijini xa ityhubhu efumanayo ivakalelwa kwi-oxyhemoglobin, ukuxutywa kokukhanya okubomvu kwe-660nm kubuthathaka, kwaye ukuxutywa kwe-910nm ukukhanya kwe-infrared kunamandla.Kumlinganiso we-oxygen yegazi, umahluko phakathi kwe-hemoglobin encitshisiweyo kunye ne-oksijini ene-oksijini ngokufumanisa umahluko phakathi kweentlobo ezimbini zokufunxa ukukhanya kumaza ohlukeneyo amaza yeyona datha isisiseko yokulinganisa ukugcwala kweoksijini egazini.Kuvavanyo lwe-oksijini yegazi, i-660nm kunye ne-910nm zezona ziqhelekileyo zamaza amaza.Ngapha koko, ukufezekisa ukuchaneka okuphezulu, ukongeza kumaza amabini, ukuya kuthi ga kwi-8 wavelengths, esona sizathu siphambili kukuba i-hemoglobin yomntu ayincitshiswanga kuphela kwi-hemoglobin.Ukongeza kwi-oxyhemoglobin, kukho ezinye ii-hemoglobins, sihlala sibona i-carboxyhemoglobin,
