“Peripheral Blood Flow Responses to Electromagnetic Energy”
This study evaluates 670 nm energy in the form of red light to stimulate blood flow changes in healthy adults. All participants will receive red light to their leg. They will also receive a continuous infusion of Definity (octafluoropropane) ultrasound contrast.
Device - 670 nm light
670 nm light emitting diode will be placed 1 cm above the gastrocnemius muscle. The diode will not be in direct contact with the skin. Subjects will be exposed to 75 mW/cm2.
Drug - octafluropropane
Octofluoropropane will be administered as a continuous infusion prior to the initiation of 670 nm light in order to measure skeletal muscle blood flow.
