An interventional study of Application of a Junctional Tourniquet in Bleeding, sponsored by Oregon Health and Science University. Completed at 1 site in United States. Open to participants aged 19 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2015-05-29.
Sponsored by Oregon Health and Science University · Not applicable, Interventional, and Treatment
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

Exclusion Criteria:
Normal subjects, all of whom undergo brief application of junctional tourniquet
Device: Application of a Junctional Tourniquet
All subjects will be studied at baseline and after placement of a junctional tourniquet to the femoral artery.
Muscle Perfusion
Contrast ultrasound perfusion imaging will be performed at baseline and 1 min after application of the JT.
