Endothelial function is measured by detecting transient increases in blood flow, a marker known as the reactive hyperemia index (RHI).
Finally, the cuff was rapidly deflated to induce a reactive hyperemia, and the above-mentioned values were recorded within one minute.
Studies in patients with SCI showed the following alterations in skin perfusion: the skin oxygenation uncompressed zone is lower in patients with SCI than in people without SCI [22-23]; the resistance of the microcirculation to external pressure, defined as the pressure caused by the closure of the capillaries, is impaired in patients with SCI [24]; the vasomotor response to a direct or alternating pressure and reactive hyperemia are impaired in people with SCI and predispose them to ischemia of the skin [25]; and finally, venous compliance is lower in people with SCI than in people without SCI [26].
