Approximately 34% of people with diabetes will experience a diabetic foot ulcer (DFU) at some point throughout their lifetime. The perfusion of oxygen to the DFU is critical for promoting wound healing and closure. However, complications from diabetes can compromise the oxygenated flow to the wound site. Techniques such as transcutaneous oximetry and laser Doppler imaging have been used to assess perfusion to DFUs at discrete point-locations in the peri-wound. Widearea measurements of temporal oxygenation changes, as an indirect measure of perfusion, can provide additional insight of the oxygenated flow in the (peri-)wound and background tissue. Herein, our objective is to assess the differences in oxygenation flow patterns in and around the DFU regions and in the feet of control subjects as a potential biomarker for monitoring wound healing … read more
