Clinical Trial 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.

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.
