WebVessel baseline diameter is inversely proportional to the level of vasodilation obtained after reactive hyperemia stimulus (major arteries dilate less that smaller arteries) and there is variability in arterial diameter from individual to individual. Therefore, it is recommended that studies provide baseline and absolute diameter variability ... Webblood re-enters. This response is called reactive hyperemia. Depending on the length of occlusion, paracrine metabolites can accumulate at higher than normal levels, resulting in a significant trigger of vasodilation when blood flow resumes. This rapid increase can cause an inflammatory response that results in more cellular damage.
