Use of Laser Speckle to Study Post Occlusive Reactive Hyperhemia in Healthy Subjects

Completed

• Conditions: Microcirculation
• Interventions: Other: tourniquet ischemia

• Registration Number: NCT01169974
• Lead Sponsor: University Hospital, Angers

Brief Summary

The investigators aim to test the hypothesis that Laser speckle contrast imaging allows for the measurement of cutaneous blood flow following various durations of tourniquet ischemia.

Detailed Description

Ischemia and post occlusive reactive hyperemia in the skin is tested in healthy normal subjects for tourniquet ischemias of 1, 2 \& 3 minutes at rest.
