Objectives
Narrative objectives1
By introducing continuous monitoring using laser Doppler flowmetry (LDF), abnormal physiological changes are possibly detected at the begining of VVR on blood donation. Suitable interventional procedure which is initialized by LDF information supposed to be effective to prevent severe reaction.

Results
Unpublished result
In the second series,204 subjects were studied, and 8 cases of VVR were observed. 6 of 8 cases were able to be analyzed without any abnormalities such as data interruption. In 4 VVR donors, the onset of VVR could be recognized by the alarm warning, and supposed to be succeeded in eraly detection. One of the other was assessed as VVR due to hypotention, although there were no symptoms.
