Study Design

Intervention model single group assignment
Masking open label
Primary purpose diagnostic
Arm
(Experimental)
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.
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).

Primary Outcomes

Measure
microcirculatory response to local pressure. Measurements are made with the Imager SPECKLE imager (LSCI) give the microvascular perfusion data in arbitrary units called perfusion units (UP).
time frame: 2 hours

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - subjects without vascular pathology Exclusion Criteria: - pregnancy - allergy tape

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
