Assessment of Limb Perfusion During Junctional Tourniquet

May 8, 2015 updated by: Jonathan R. Lindner, MD, Oregon Health and Science University
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
