Abstract

A presente invenção refere-se uma sonda de oxímetro que leva em consideração a cor de tecido (por exemplo, cor de pele ou conteúdo de melanina) para aperfeiçoar a precisão quando determinando a saturação de oxigênio do tecido. Uma luz é transmitida de uma fonte de luz para dentro do tecido que tem melanina (por exemplo, eumelanina ou feomelanina). A luz refletida do tecido é recebida por um detector. Um fator de compensação é determinado para levar em conta a absorção devido à melanina. O oxímetro utiliza este fator de compensação e determina um valor de saturação de oxigênio corrigido em melanina.
