Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to use contrast enhanced ultrasound to determine the degree to which flow is reduced during application of a junctional tourniquet (JT). Contrast enhanced ultrasound is performed to quantify thigh and calf perfusion at baseline and during application of the JT
