Résumé
Pulsatile blood oxygen saturation ( We developed an optical pulse oximetry method based on dual-ratio (DR) measurements to suppress individual anatomical confounds on We designed a DR-based finger pulse oximeter, hypothesizing that DR would suppress confounds from optical coupling and superficial tissue absorption. This method is tested using Monte Carlo simulations and Different melanosome volume fractions in the epidermis, a surrogate for skin tone, cause changes in the recovered For the models and methods considered here,
