Detailed Description

Measure microcirculatory responses after localized ischemia obtained by local application of pressure (laser speckle). The purpose of this study is to perform measurements of the methodological points made.

The study will investigate :

  • The effect of the duration and intensity of the pressure
  • The reproducibility of measurements
  • The correlation with ischemic hyperemia post

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: microcirculatory responses

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.
Other: microcirculatory responses

The effect of the duration and intensity of the pressure; reproducibility and correlation with ischemic hyperemia post.

measurements are made with the Imager SPECKLE imager (LSCI) give the microvascular perfusion data in arbitrary units called perfusion units (UP).
