Abstract

A non-contact device for measuring oxygen saturation during wound healing was fabricated using a multi-spectral camera and LEDs of two different wavelengths (660 nm and 940 nm). The performance of the system was evaluated by creating a wound model and measuring oxygen saturation during the healing process. The results showed a decrease in oxygen saturation due to hypoxia immediately after wounding, which gradually returned to normal as the wound healed. Moreover, the accuracy of the system was compared with commercial veterinary oximeters, and the root mean square error (RMSE) was found to meet the clinical criteria (≤ 3.5%).
