Post-occlusive reactive hyperemia variables can be used to diagnose vascular dysfunction in hemorrhagic shock.

Introduction: Laser doppler flowmetry (LDF) allows non-invasive assessment of microvascular functions. The combination of LDF with an occlusion functional test enables study of post-occlusive reactive hyperemia (PORH), providing additional information about vasomotor function, capillary blood flow reserve, and the overall reactivity of the microvascular system.

Aim: To identify early alterations of PORH variables in the skin of a rat in hemorrhagic shock (HS).
