Abstract

We investigated a method to perform measurements of tissue oxygen saturation (StO₂) in real-time, using a digital red– green–blue (RGB) camera. Concentrations of oxygenated hemoglobin (C_HbO) and deoxygenated hemoglobin (C_HbR) were estimated from videos of the human face using a method based on a tissue-like light transport model of the skin. StO₂ was calculated from the values of C_HbO and C_HbR. In vivo experiments with human volunteers while varying the fraction of inspired oxygen were performed to evaluate the comparability of the proposed method with a commercially available device for StO₂ measurement.
