WebVasodilation. Vasodilation is the medical term for when blood vessels in your body widen, allowing more blood to flow through them and lowering your blood pressure. This process happens normally in your body without you realizing it. It can be caused by things you … Flow-mediated dilation (FMD) refers to dilation (widening) of an artery when blood flow increases in that artery. The primary cause of FMD is release of nitric oxide by endothelial cells. To determine FMD, brachial artery dilation following a transient period of forearm ischemia is measured using ultrasound. Because the value of FMD can be compromised when improperly applied, attempts have been made to standardize the methodology for measuring FMD.
