WebMar 11, 2024 · Given that NO is a key determinant of flow-mediated dilation (42, 106), which peaks within ~45–90 s after cuff deflation (10, 21, 37, 106), it is likely that the role of NO in the sustained hyperemic response is dependent on shear-stimulated activation of eNOS following cuff deflation, and not synthesis of NO during the ischemic period. WebFeb 1, 2024 · These observations prompted introduction of the “flow-mediated dilation (FMD)” approach as an in vivo bioassay of endothelium-dependent vascular relaxation in humans.
