microcirculatory responses

Experimental group

Description:

Measure microcirculatory responses after localized ischemia obtained by local application of pressure (laser speckle). A pressure is applied to the subject's arm. this causes a localized ischemia. the measures responses to this ischemia will be made by the imager speckle (LSCI) give the microvascular perfusion data.

Treatment:

Other: microcirculatory responses
