Abstract

This paper briefly reviews the feasibility of using multispectral imaging approach to noninvasively determine one's mean blood oxygen saturation, SmO2. We described the use of Extended Modified Lambert Beer (EMLB) model and a nonlinear fitting algorithm to quantitatively analyse the measured spectroscopic data over a wavelength range of 520-600 nm to give the best estimation of SmO2. The experimental work required spectroscopic images to be collected from the right index finger of four recruited volunteers at resting condition and after a pressure of 140 mmHg is applied on their upper right arm. The obtained results revealed a percent SmO2 of 77.5 ± 1.06% at resting condition and 54.3 ± 0.42% during blood flow occlusion. These results are also compared to that reported in previous works. The results show that these ranges and the drop in the mean percent SmO2 obtained for at rest compared to blood flow occlusion condition agreed considerably well with that reported in the literature. This work concluded that the developed multispectral imaging system could potentially be used as an alternative means to noninvasive monitoring and detection of changes in one's mean blood oxygen saturation with external interventions.
