This work presents the development a portable optical system for telemonitoring of tissue oxygen status with unlimited skin access. The results showed that this system is able to detect comparable decrease in the βRG values following an interruption in the supply of oxygen carrying blood to the local tissues. This work observed an average difference in βRG for at rest and blood occlusion experiments calculated as 0.24 ± 0.01; this predicted value is also found to be relatively consistent for different experiments performed across the considered skin sites. It was found that the variability in βRG is associated with the differences in the light absorption of hemoglobin components across different color region following changes in the microcirculation activities. This study concluded that the employed system may be suitably used for non-invasive measurement of skin oxygen status.
