Abstract
An apparatus and method for evaluating perfusion adjacent a skin surface includes the steps of measuring a reference rate of perfusion of the skin surface, storing the reference rate of perfusion, and applying a positive force to the skin surface. The apparatus and method also includes the steps of measuring a second rate of perfusion adjacent the skin surface after the positive force is applied, and calculating a differential rate of perfusion between the reference rate of perfusion and the second rate of perfusion after positive force is applied to provide an indication of perfusion adjacent the skin surface. The apparatus and method further includes the step of displaying the indication of perfusion.
