The advent of tourniquets employing digital technology has led to significant improvements in the safety and accuracy of surgical procedures performed with an occlusive cuff applied proximally on a limb. This article describes the evaluation of new cuffs used on fingers that may permit significantly lower pressures to be more safely and consistently employed. Our experimental studies would suggest that finger occlusion pressure is a function of cuff design, cuff width, finger circumference, and systolic blood pressure.
